- **在Activity布局中添加Fragment**：在activity_main.xml中，使用<fragment>标签将Fragment添加到Activity布局中，指定Fragment的ID和对应的类名。 xml <LinearLayout ...> <fragment android:id="@+id/...

Android Fragment的静态注册和动态注册创建步骤

3. 在 StaticFragment.java 中重载 onCreateView() 方法，通过调用 inflater.inflate() 方法并传入布局资源 ID 生成 Fragment 的视图资源。 4. 在 static_fragment.xml 中定义 Fragment 的视图资源，例如 Button、...

package com.example.dzy; import android.app.Dialog; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.drawable.BitmapDrawable; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import android.widget.LinearLayout; import androidx.annotation.NonNull; import androidx.annotation.Nullable; import androidx.fragment.app.Fragment; import java.io.InputStream; public class Fragment_1 extends Fragment { private ImageView imageView_1,imageView_2; @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.activity_shouye, container, false); imageView_1=(ImageView)view.findViewById(R.id.image_show1); imageView_1.setImageBitmap(bitmap); return view; } Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.show1); bigImageLoader(bitmap); //方法里直接实例化一个imageView不用xml文件，传入bitmap设置图片 private void bigImageLoader(Bitmap bitmap){ final Dialog dialog = new Dialog(getActivity()); ImageView image = new ImageView(getContext()); image.setImageBitmap(bitmap); dialog.setContentView(image); //将dialog周围的白块设置为透明 dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent); //显示 dialog.show(); //点击图片取消 image.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View v){ dialog.cancel(); } }); } }这段代码应如何修改

public class Fragment_1 extends Fragment { private ImageView imageView_1,imageView_2; @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup ...

public class ThreeFragment extends Fragment { public ThreeFragment() { // Required empty public constructor } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment return inflater.inflate(R.layout.fragment_three, container, false); } }

这是一个使用了 Android Fragment 的代码。Fragment 可以看作是 Activity 内部的模块，可以被动态添加到 Activity 中...在该方法中，使用了 LayoutInflater 对象将布局文件解析为 View 对象，并将其返回，供系统使用。

public class HomeFragment extends Fragment { private Context mContext; private HomeViewModel homeViewModel; private RollPagerView mRollPagerView; String data; private EditText serachinput; private Button serach; private ListView componlist; private Handler handler = null; public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { homeViewModel = ViewModelProviders.of(this).get(HomeViewModel.class); final View root = inflater.inflate(R.layout.fragment_home, container, false); mContext = getContext(); handler = new Handler(); serachinput = root.findViewById(R.id.componserachinput); serach = root.findViewById(R.id.serachcompon); componlist = root.findViewById(R.id.componlist); mRollPagerView = root.findViewById(R.id.roll_view_pager); //设置播放时间间隔 mRollPagerView.setPlayDelay(3000); //设置透明度 mRollPagerView.setAnimationDurtion(500); //设置适配器 mRollPagerView.setAdapter(new TestNormalAdapter()); //设置圆点指示器颜色 mRollPagerView.setHintView(new ColorPointHintView(getContext(), Color.YELLOW, Color.WHITE)); serach.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { serach(serachinput.getText().toString()); } }); load(); return root;

在 onCreateView() 方法中，首先通过 ViewModelProviders 获取 HomeViewModel 实例，然后使用 inflater 对布局文件 R.layout.fragment_home 进行解析，并将解析的视图返回。在视图中，分别获取了 componserachinput...

package com.example.reciteword; import android.content.Context; import android.content.SharedPreferences; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button; import android.widget.ImageButton; import android.widget.ListView; import android.widget.TextView; import androidx.fragment.app.Fragment; import java.util.ArrayList; import java.util.List; import java.util.Random; public class wrongFragment extends Fragment { private List<Word> wordList = new ArrayList<>(); @Override public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_wrong, container, false); } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); final SharedPreferences sharedPre = getActivity().getSharedPreferences("t",Context.MODE_PRIVATE); final int[] wrongNum = {sharedPre.getInt("wrongNum", 0)}; System.out.println(wrongNum[0]); wordList.clear(); for(int i = 1;i<=wrongNum[0];i++){ int temp = sharedPre.getInt("wrong"+i, 0); Word word = new Word(Data.getWord(temp),Data.getPron(temp),Data.getwordDefine(temp),sharedPre.getInt("word"+temp,1),0); System.out.println(Data.getRandNum()+":"+sharedPre.getInt("word"+temp,9)); wordList.add(word); } WordAdapter adapter = new WordAdapter(getActivity(),R.layout.word_item,wordList); ListView listView = (ListView) getActivity().findViewById(R.id.wrong_list_view); listView.setAdapter(adapter); } }这段代码有什么用

1. 从布局文件 R.layout.fragment_wrong 中获取界面布局，即 onCreateView 方法。 2. 从 SharedPreferences 中获取用户答错的单词列表，然后将这些单词封装成 Word 对象并添加到 wordList 中，即 onActivityCreated ...

以下代码中,如何把参数String message修改为 SpannableStringBuilder message;public class FragmentJiaoBanDay0 extends Fragment { private static final String ARG_NAME = "name"; private static final String ARG_MESSAGE = "message"; private String mName; private String mMessage; /** * 这个程序其实不作修改时是可以不用的;因为目前调用的是相同的一个 * @param name * @param message * @return */ public static com.example.zhgw.DanWeiXinXi.FragmentDanWeiXinXi newInstance(String name, String message) { com.example.zhgw.DanWeiXinXi.FragmentDanWeiXinXi fragment = new com.example.zhgw.DanWeiXinXi.FragmentDanWeiXinXi(); Bundle args = new Bundle(); args.putString(ARG_NAME, name); args.putString(ARG_MESSAGE, message); fragment.setArguments(args); return fragment; } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (getArguments() != null) { mName = getArguments().getString(ARG_NAME); mMessage = getArguments().getString(ARG_MESSAGE); } } @SuppressLint("MissingInflatedId") @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_jiao_ban_day0, container, false); TextView messageTextView = view.findViewById(R.id.messageTextView); messageTextView.setText(mMessage); return view; } }

你可以将参数 String message 修改为 SpannableStringBuilder message，并相应...最后，在 onCreateView() 方法中，我们将 SpannableStringBuilder 对象设置到 TextView 控件上，同样使用 setText() 方法。

public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); setContentView(R.layout.fragment_main); TypedValue typedValue = new TypedValue(); context.getTheme().resolveAttribute(R.attr.lvBackground, typedValue, true); Log.d(TAG, "onCreate: " + typedValue.data + " " + typedValue.resourceId); Log.d(TAG, "onCreate: " + getActivity().getTheme().toString()); btn = (FloatingActionButton) findViewById(R.id.fab); lv = findViewById(R.id.lv); myToolbar = findViewById(R.id.myToolbar); adapter = new NoteAdapter(getApplicationContext(), noteList); refreshListView(); lv.setAdapter(adapter); setSupportActionBar(myToolbar); getSupportActionBar().setHomeButtonEnabled(true); getSupportActionBar().setDisplayHomeAsUpEnabled(true); //设置toolbar取代actionBar initPopUpView(); myToolbar.setNavigationIcon(R.drawable.ic_menu_black_24dp); myToolbar.setNavigationOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Log.d(TAG, "onClick: shit"); showPopUpView(); } });怎么修改

1. 将继承关系由Activity改为Fragment，即将类声明改为public class MainFragment extends Fragment { 2. 修改onActivityCreated()方法，重写onCreateView()方法，用LayoutInflater.inflate()方法加载布局文件，...

3. 在Activity中加载一个Fragment的基本流程，CrimeFragment代码package com.example.ciriminalintent; import android.os.Bundle; import android.text.Editable; import android.text.TextWatcher; import android.view.LayoutInflater; import android.view.View; import android.view.
