Android仿QQ长按弹出删除复制框 Android仿QQ长按弹出删除复制框

废话不说，先看一下效果图：

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();
 }
 
 
}

更详细的配置：

popupList.setIndicatorView(View)
popupList.setIndicatorSize(int, int)
popupList.setNormalBackgroundColor(int)
popupList.setPressedBackgroundColor(int)
popupList.setNormalTextColor(int)
popupList.setPressedTextColor(int)
popupList.setDividerColor(int)
popupList.setTextSize(float)
popupList.setTextPadding(int, int, int, int)
popupList.setTextPaddingLeft(int)
popupList.setTextPaddingTop(int)
popupList.setTextPaddingRight(int)
popupList.setTextPaddingBottom(int)
popupList.setBackgroundCornerRadius(int)
popupList.setDividerWidth(int)
popupList.setDividerHeight(int)
