public void onClick(View v) { String key = inflate.messageEdit.getText().toString(); if (TextUtils.isEmpty(key)){ homeAdapter.clear(); homeAdapter.addAll(goodsTbList); return; } List<GoodsTb> tempList = new ArrayList<>(); for (int i = 0; i < goodsTbList.size(); i++) { if (goodsTbList.get(i).getBook_names().contains(key)){ tempList.add(goodsTbList.get(i)); } }

这段代码是一个点击事件的监听器，在用户点击某个控件时执行。当用户点击时，它会获取一个输入框中的字符串，并判断是否为空。如果字符串为空，则清空 `homeAdapter` 中的数据，然后将 `goodsTbList` 中的所有数据添加到 `homeAdapter` 中。如果字符串不为空，则遍历 `goodsTbList` 列表，查找其中 `book_names` 字段包含该字符串的所有数据，然后将它们添加到 `tempList` 中。最后将 `tempList` 中的数据添加到 `homeAdapter` 中。这段代码的作用是根据用户输入的关键字，动态过滤出符合条件的数据并显示在列表中。

    }
}

这个程序实现了以下功能：

1. 用户可以通过输入中英文来添加单词；
2. 用户可以随意开关某个单词的中文释义；
3. 用户可以删除已经添加的单词；
4. 用户关机或者退出应用不会导致单词本内的单词丢失；
5. 用户可以自定义单词本中单词的顺序；
6. 用户可以选择自己喜欢的界面风格；
7. 用户可以快捷的查找某个单词在有道上的详细信息；
8. 用户可以查找某个单词。

如何写一个安卓开发跑步运动程序功能包括闪烁页面登录，主页面包括开始运动(计步)、结束运动(计步)、查看记录；开始打卡(上传数据)、GPS定位、查看GPS、查询打卡、设置路径、打卡页面、GPS轨迹、自我定位、路径规划、计步查询，还有运动打卡功能写出代码和过程

由于这是一个比较复杂的安卓应用程序，下面我只能为您提供大致的思路和代码框架，您需要根据自己的需求和实际情况进行具体的代码实现。

1. 创建闪烁页面和登录页面

闪烁页面可以使用Handler实现，代码如下：

public class SplashActivity extends AppCompatActivity {
    private static final int DELAY_TIME = 2000;
    private boolean isFinish = false;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                if (!isFinish) {
                    Intent intent = new Intent(SplashActivity.this, LoginActivity.class);
                    startActivity(intent);
                    finish();
                }
            }
        }, DELAY_TIME);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        isFinish = true;
    }
}

登录页面可以通过EditText和Button控件实现用户输入和登录验证，代码如下：

public class LoginActivity extends AppCompatActivity {
    private EditText mEtUserName;
    private EditText mEtPassword;
    private Button mBtnLogin;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        mEtUserName = findViewById(R.id.et_user_name);
        mEtPassword = findViewById(R.id.et_password);
        mBtnLogin = findViewById(R.id.btn_login);

        mBtnLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String userName = mEtUserName.getText().toString().trim();
                String password = mEtPassword.getText().toString().trim();
                if (TextUtils.isEmpty(userName) || TextUtils.isEmpty(password)) {
                    Toast.makeText(LoginActivity.this, "请输入用户名和密码", Toast.LENGTH_SHORT).show();
                } else {
                    // TODO: 进行登录验证
                }
            }
        });
    }
}

2. 创建主页面

主页面可以通过TabLayout和ViewPager实现多个功能模块的切换，代码如下：

public class MainActivity extends AppCompatActivity {
    private TabLayout mTabLayout;
    private ViewPager mViewPager;
    private List<String> mTitleList = new ArrayList<>();
    private List<Fragment> mFragmentList = new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTabLayout = findViewById(R.id.tab_layout);
        mViewPager = findViewById(R.id.view_pager);

        mTitleList.add("开始运动");
        mTitleList.add("打卡");
        mTitleList.add("GPS定位");
        mTitleList.add("路径规划");
        mTitleList.add("计步查询");

        mFragmentList.add(new StartRunFragment());
        mFragmentList.add(new PunchFragment());
        mFragmentList.add(new GPSFragment());
        mFragmentList.add(new PathFragment());
        mFragmentList.add(new StepFragment());

        mViewPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
        mTabLayout.setupWithViewPager(mViewPager);
    }

    class MyPagerAdapter extends FragmentPagerAdapter {

        public MyPagerAdapter(@NonNull FragmentManager fm) {
            super(fm);
        }

        @NonNull
        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        @Nullable
        @Override
        public CharSequence getPageTitle(int position) {
            return mTitleList.get(position);
        }
    }
}

3. 实现开始运动和结束运动的计步功能

可以通过SensorManager和SensorEventListener实现计步功能，代码如下：

public class StartRunFragment extends Fragment implements SensorEventListener {
    private SensorManager mSensorManager;
    private Sensor mStepSensor;
    private TextView mTvStepCount;
    private Button mBtnStartRun;
    private Button mBtnStopRun;
    private int mStepCount = 0;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_start_run, container, false);
        mTvStepCount = view.findViewById(R.id.tv_step_count);
        mBtnStartRun = view.findViewById(R.id.btn_start_run);
        mBtnStopRun = view.findViewById(R.id.btn_stop_run);

        mSensorManager = (SensorManager) getActivity().getSystemService(Context.SENSOR_SERVICE);
        if (mSensorManager != null) {
            mStepSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER);
            if (mStepSensor == null) {
                Toast.makeText(getActivity(), "设备不支持计步器", Toast.LENGTH_SHORT).show();
            }
        }

        mBtnStartRun.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (mStepSensor != null) {
                    mSensorManager.registerListener(StartRunFragment.this, mStepSensor, SensorManager.SENSOR_DELAY_UI);
                    Toast.makeText(getActivity(), "开始计步", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getActivity(), "设备不支持计步器", Toast.LENGTH_SHORT).show();
                }
            }
        });

        mBtnStopRun.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mSensorManager.unregisterListener(StartRunFragment.this);
                Toast.makeText(getActivity(), "停止计步", Toast.LENGTH_SHORT).show();
            }
        });

        return view;
    }

    @Override
    public void onSensorChanged(SensorEvent event) {
        if (event.sensor.getType() == Sensor.TYPE_STEP_COUNTER) {
            int step = (int) event.values[0];
            if (mStepCount == 0) {
                mStepCount = step;
            }
            int count = step - mStepCount;
            mTvStepCount.setText("步数：" + count);
        }
    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {

    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        mSensorManager.unregisterListener(this);
    }
}

4. 实现打卡功能

可以通过网络请求和数据库操作实现打卡功能，代码如下：

public class PunchFragment extends Fragment {
    private EditText mEtPunchContent;
    private Button mBtnPunch;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_punch, container, false);
        mEtPunchContent = view.findViewById(R.id.et_punch_content);
        mBtnPunch = view.findViewById(R.id.btn_punch);

        mBtnPunch.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String content = mEtPunchContent.getText().toString().trim();
                if (TextUtils.isEmpty(content)) {
                    Toast.makeText(getActivity(), "请输入打卡内容", Toast.LENGTH_SHORT).show();
                } else {
                    // TODO: 进行打卡上传和数据库操作
                }
            }
        });

        return view;
    }
}

5. 实现GPS定位功能

可以通过LocationManager和LocationListener实现GPS定位功能，代码如下：

public class GPSFragment extends Fragment implements LocationListener {
    private LocationManager mLocationManager;
    private TextView mTvLocationInfo;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_gps, container, false);
        mTvLocationInfo = view.findViewById(R.id.tv_location_info);

        mLocationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
        if (mLocationManager != null) {
            if (ActivityCompat.checkSelfPermission(getActivity(),
                    Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(getActivity(),
                        new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
            } else {
                mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
                        1000, 1, this);
            }
        }

        return view;
    }

    @Override
    public void onLocationChanged(Location location) {
        String info = "经度：" + location.getLongitude() + "\n纬度：" + location.getLatitude();
        mTvLocationInfo.setText(info);
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {

    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onProviderDisabled(String provider) {

    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        mLocationManager.removeUpdates(this);
    }
}

6. 实现GPS轨迹功能

可以通过MapView和BaiduMap实现GPS轨迹功能，代码如下：

public class TrackFragment extends Fragment implements OnMapReadyCallback {
    private MapView mMapView;
    private BaiduMap mBaiduMap;
    private PolylineOptions mPolylineOptions;
    private List<LatLng> mLatLngList = new ArrayList<>();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_track, container, false);
        mMapView = view.findViewById(R.id.map_view);
        mMapView.onCreate(savedInstanceState);
        mMapView.getMapAsync(this);

        return view;
    }

    @Override
    public void onMapReady(BaiduMap baiduMap) {
        mBaiduMap = baiduMap;
        mBaiduMap.setMyLocationEnabled(true);
        mBaiduMap.setMapStatus(MapStatusUpdateFactory.zoomTo(18));
    }

    private void addLatLng(LatLng latLng) {
        if (mPolylineOptions == null) {
            mPolylineOptions = new PolylineOptions();
            mPolylineOptions.width(10);
            mPolylineOptions.color(Color.BLUE);
            mPolylineOptions.points(mLatLngList);
            mBaiduMap.addOverlay(mPolylineOptions);
        } else {
            mLatLngList.add(latLng);
            mPolylineOptions.points(mLatLngList);
        }
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        mMapView.onDestroy();
    }
}

7. 实现路径规划功能

可以通过BaiduMapRoutePlan和RoutePlanSearch实现路径规划功能，代码如下：

public class PathFragment extends Fragment implements OnGetRoutePlanResultListener {
    private MapView mMapView;
    private BaiduMap mBaiduMap;
    private EditText mEtStart;
    private EditText mEtEnd;
    private Button mBtnSearch;
    private RoutePlanSearch mRoutePlanSearch;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_path, container, false);
        mMapView = view.findViewById(R.id.map_view);
        mMapView.onCreate(savedInstanceState);
        mBaiduMap = mMapView.getMap();
        mEtStart = view.findViewById(R.id.et_start);
        mEtEnd = view.findViewById(R.id.et_end);
        mBtnSearch = view.findViewById(R.id.btn_search);

        mRoutePlanSearch = RoutePlanSearch.newInstance();
        mRoutePlanSearch.setOnGetRoutePlanResultListener(this);

        mBtnSearch.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String start = mEtStart.getText().toString().trim();
                String end = mEtEnd.getText().toString().trim();
                PlanNode startNode = PlanNode.withCityNameAndPlaceName("北京", start);
                PlanNode endNode = PlanNode.withCityNameAndPlaceName("北京", end);
                mRoutePlanSearch.drivingSearch(new DrivingRoutePlanOption().from(startNode).to(endNode));
            }
        });

        return view;
    }

    @Override
    public void onGetDrivingRoutePlanResult(DrivingRoutePlanResult drivingRoutePlanResult) {
        if (drivingRoutePlanResult != null && drivingRoutePlanResult.getRouteLines() != null
                && drivingRoutePlanResult.getRouteLines().size() > 0) {
            DrivingRouteOverlay overlay = new DrivingRouteOverlay(mBaiduMap);
            overlay.setData(drivingRoutePlanResult.getRouteLines().get(0));
            overlay.addToMap();
            overlay.zoomToSpan();
        } else {
            Toast.makeText(getActivity(), "未搜索到结果", Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void onGetWalkingRoutePlanResult(WalkingRoutePlanResult walkingRoutePlanResult) {

    }

    @Override
    public void onGetTransitRoutePlanResult(TransitRoutePlanResult transitRoutePlanResult) {

    }

    @Override
    public void onGetMassTransitRoutePlanResult(MassTransitRoutePlanResult massTransitRoutePlanResult) {

    }

    @Override
    public void onGetBikingRoutePlanResult(BikingRoutePlanResult bikingRoutePlanResult) {

    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        mMapView.onDestroy();
        mRoutePlanSearch.destroy();
    }
}

8. 实现计步查询功能

可以通过SQLiteOpenHelper和Cursor实现计步查询功能，代码如下：

public class StepFragment extends Fragment {
    private StepDatabaseHelper mDatabaseHelper;
    private ListView mLvStepRecord;
    private List<StepRecord> mStepRecordList = new ArrayList<>();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_step, container, false);
        mLvStepRecord = view.findViewById(R.id.lv_step_record);

        mDatabaseHelper = new StepDatabaseHelper(getActivity());
        SQLiteDatabase db = mDatabaseHelper.getWritableDatabase();
        Cursor cursor = db.query(StepDatabaseHelper.TABLE_NAME, null, null, null, null, null, null);
        while (cursor.moveToNext()) {
            int id = cursor.getInt(cursor.getColumnIndex("_id"));
            String date = cursor.getString(cursor.getColumnIndex("date"));
            int stepCount = cursor.getInt(cursor.getColumnIndex("step_count"));
            StepRecord stepRecord = new StepRecord(id, date, stepCount);
            mStepRecordList.add(stepRecord);
        }
        cursor.close();

        StepRecordAdapter adapter = new StepRecordAdapter(getActivity(), mStepRecordList);
        mLvStepRecord.setAdapter(adapter);

        return view;
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        mDatabaseHelper.close();
    }
}
