Android仿QQ長按彈出刪除復(fù)制框
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)
