本文实例为大家分享了Android仿QQ长按删除弹出框的具体代码，供大家参考，具体内容如下

废话不说，先看一下效果图：

Android,QQ,删除,复制框

对于列表来说，如果想操作某个列表项，一般会采用长按弹出菜单的形式，默认的上下文菜单比较难看，而QQ的上下文菜单就人性化多了，整个菜单给用户一种气泡弹出的感觉，而且会显示在手指按下的位置，而技术实现我之前是使用popupWindow和RecyclerView实现的，上面一个RecyclerView，下面一个小箭头ImageView，但后来发现没有必要，而且可定制化也不高，还是使用多个TextView更好一点。

我封装了一下，只需要一个PopupList.java文件。源码放在了git上，git地址

使用方式，很简单：

只需要一个PopupList.java文件和几行代码，你就可以为ListView，GridView，甚至任意View绑定一个长按弹出的水平气泡式菜单。
你可以这样使用：

public class MainActivity extends AppCompatActivity {   private Button btn_long_click; private ListView lv_main; private List<String> mDataList = new ArrayList<>(); private ArrayAdapter<String> mDataAdapter; private List<String> popupMenuItemList = new ArrayList<>();   @Override protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.activity_main);  btn_long_click = (Button) findViewById(R.id.btn_long_click);  lv_main = (ListView) findViewById(R.id.lv_main);  mDataAdapter = new ArrayAdapter<>(this, android.R.layout.simple_expandable_list_item_1, mDataList);  lv_main.setAdapter(mDataAdapter);    popupMenuItemList.add(getString(R.string.copy));  popupMenuItemList.add(getString(R.string.delete));  popupMenuItemList.add(getString(R.string.share));  popupMenuItemList.add(getString(R.string.more));  PopupList popupList = new PopupList(this);  popupList.bind(lv_main, popupMenuItemList, new PopupList.PopupListListener() {   @Override   public boolean showPopupList(View adapterView, View contextView, int contextPosition) {    return true;   }     @Override   public void onPopupListClick(View contextView, int contextPosition, int position) {    Toast.makeText(MainActivity.this, contextPosition + "," + position, Toast.LENGTH_SHORT).show();   }  });    PopupList normalViewPopupList = new PopupList(this);  normalViewPopupList.bind(btn_long_click, popupMenuItemList, new PopupList.PopupListListener() {   @Override   public boolean showPopupList(View adapterView, View contextView, int contextPosition) {    return true;   }     @Override   public void onPopupListClick(View contextView, int contextPosition, int position) {    Toast.makeText(MainActivity.this, contextPosition + "," + position, Toast.LENGTH_SHORT).show();   }  });    lv_main.setOnItemClickListener(new AdapterView.OnItemClickListener() {   @Override   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {    Toast.makeText(MainActivity.this, "onItemClicked:" + position, Toast.LENGTH_SHORT).show();   }  });  btn_long_click.setOnClickListener(new View.OnClickListener() {   @Override   public void onClick(View v) {    startActivity(new Intent(MainActivity.this, SecondaryActivity.class));   }  });  getData(); }   private void getData() {  for (int i = 0; i < 40; i++) {   mDataList.add("No." + i);  }  mDataAdapter.notifyDataSetChanged(); }  }

注意：`bind()`方法要求你的anchorView不能有touch和longClick/itemLongClick监听，因为`bind()`方法会主动给anchorView设置监听器：

mAnchorView.setOnTouchListener(new View.OnTouchListener() {  @Override  public boolean onTouch(View v, MotionEvent event) {   mRawX = event.getRawX();   mRawY = event.getRawY();   return false;  } }); if (mAnchorView instanceof AbsListView) {  ((AbsListView) mAnchorView).setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {   @Override   public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {    if (mPopupListListener != null      && !mPopupListListener.showPopupList(parent, view, position)) {     return false;    }    mAdapterView = parent;    mContextView = view;    mContextPosition = position;    showPopupListWindow();    return true;   }  }); } else {  mAnchorView.setOnLongClickListener(new View.OnLongClickListener() {   @Override   public boolean onLongClick(View v) {    if (mPopupListListener != null      && !mPopupListListener.showPopupList(v, v, 0)) {     return false;    }    mContextView = v;    mContextPosition = 0;    showPopupListWindow();    return true;   }  }); }

这就限制了anchorView不能再添加touch监听，不能添加longClick监听，如果你需要添加监听可以使用`showPopupListWindow`方法主动来显示弹出框，而不是使用`bind()`方法：

public class SecondaryActivity extends AppCompatActivity {   private ListView lv_main; private List<String> mDataList = new ArrayList<>(); private ArrayAdapter<String> mDataAdapter; private List<String> popupMenuItemList = new ArrayList<>(); private float mRawX; private float mRawY;   @Override protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.activity_secondary);  lv_main = (ListView) findViewById(R.id.lv_main);  mDataAdapter = new ArrayAdapter<>(this, android.R.layout.simple_expandable_list_item_1, mDataList);  lv_main.setAdapter(mDataAdapter);    popupMenuItemList.add(getString(R.string.copy));  popupMenuItemList.add(getString(R.string.delete));  popupMenuItemList.add(getString(R.string.share));  popupMenuItemList.add(getString(R.string.more));    lv_main.setOnTouchListener(new View.OnTouchListener() {   @Override   public boolean onTouch(View v, MotionEvent event) {    mRawX = event.getRawX();    mRawY = event.getRawY();    return false;   }  });  lv_main.setOnItemClickListener(new AdapterView.OnItemClickListener() {   @Override   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {    Toast.makeText(SecondaryActivity.this, "onItemClicked:" + position, Toast.LENGTH_SHORT).show();   }  });  lv_main.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {   @Override   public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {    PopupList popupList = new PopupList(view.getContext());    popupList.showPopupListWindow(view, position, mRawX, mRawY, popupMenuItemList, new PopupList.PopupListListener() {     @Override     public boolean showPopupList(View adapterView, View contextView, int contextPosition) {      return true;     }       @Override     public void onPopupListClick(View contextView, int contextPosition, int position) {      Toast.makeText(contextView.getContext(), contextPosition + "," + position, Toast.LENGTH_SHORT).show();     }    });    return true;   }  });  getData(); }   private void getData() {  for (int i = 0; i < 40; i++) {   mDataList.add("No." + i);  }  mDataAdapter.notifyDataSetChanged(); }  }
