這篇文章主要為大家詳細(xì)介紹了Android仿QQ長按彈出刪除、復(fù)制、轉(zhuǎn)發(fā)框，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了Android仿QQ長按刪除彈出框的具體代碼，供大家參考，具體內(nèi)容如下

廢話不說，先看一下效果圖：

對于列表來說，如果想操作某個列表項，一般會采用長按彈出菜單的形式，默認(rèn)的上下文菜單比較難看，而QQ的上下文菜單就人性化多了，整個菜單給用戶一種氣泡彈出的感覺，而且會顯示在手指按下的位置，而技術(shù)實現(xiàn)我之前是使用popupWindow和RecyclerView實現(xiàn)的，上面一個RecyclerView，下面一個小箭頭ImageView，但后來發(fā)現(xiàn)沒有必要，而且可定制化也不高，還是使用多個TextView更好一點。

我封裝了一下，只需要一個PopupList.java文件。源碼放在了git上，git地址     

使用方式，很簡單：

只需要一個PopupList.java文件和幾行代碼，你就可以為ListView，GridView，甚至任意View綁定一個長按彈出的水平氣泡式菜單。
你可以這樣使用：

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監(jiān)聽，因為`bind()`方法會主動給anchorView設(shè)置監(jiān)聽器：

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;
   }
  });
 }

這就限制了anchorView不能再添加touch監(jiān)聽，不能添加longClick監(jiān)聽，如果你需要添加監(jiān)聽可以使用`showPopupListWindow`方法主動來顯示彈出框，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();
 }
 
 
}

更詳細(xì)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)
