用android studio写带定位的打卡软件

好的，下面是一个简单的带定位的打卡软件的实现步骤：

1. 创建一个新的Android Studio项目，添加所需的依赖库。
2. 在AndroidManifest.xml文件中添加以下权限：

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

3. 在布局文件中添加一个按钮和一个TextView，用于显示定位信息。
4. 在MainActivity.java中，添加以下代码：

public class MainActivity extends AppCompatActivity implements LocationListener {

    private Button mButton;
    private TextView mTextView;
    private LocationManager mLocationManager;

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

        mButton = findViewById(R.id.button);
        mTextView = findViewById(R.id.textview);

        mLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        mButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getLocation();
            }
        });
    }

    private void getLocation() {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
                ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
        } else {
            Location location = mLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
            if (location != null) {
                double latitude = location.getLatitude();
                double longitude = location.getLongitude();
                mTextView.setText("Latitude: " + latitude + "\nLongitude: " + longitude);
            } else {
                mTextView.setText("Unable to get location.");
            }
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == 1) {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                getLocation();
            } else {
                mTextView.setText("Permission denied.");
            }
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
                ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
        } else {
            mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
        }
    }

    @Override
    protected void onPause() {
        super.onPause();
        mLocationManager.removeUpdates(this);
    }

    @Override
    public void onLocationChanged(Location location) {
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
        mTextView.setText("Latitude: " + latitude + "\nLongitude: " + longitude);
    }

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

    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onProviderDisabled(String provider) {

    }
}

5. 运行程序，点击按钮即可获取当前位置信息。

请注意，此代码仅提供了一个基本的示例，需要根据实际需求进行进一步的开发和调整。
