Androidlistview 的侧滑删除仿的QQ效果的几种实现方式

1 自定义view继承自ListView的实现方法

1）主要核心代码

package com.example.listviewitemslidedeletebtnshow;

import android.content.Context;
import android.util.AttributeSet;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewConfiguration;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.PopupWindow;

public class QQListView extends ListView {

private static final String TAG = "QQlistView";

// private static final int VELOCITY_SANP = 200;
// private VelocityTracker mVelocityTracker;
/**
* 用户滑动的最小距离
*/
private int touchSlop;

/**
* 是否响应滑动
*/
private boolean isSliding;

/**
* 手指按下时的x坐标
*/
private int xDown;
/**
* 手指按下时的y坐标
*/
private int yDown;
/**
* 手指移动时的x坐标
*/
private int xMove;
/**
* 手指移动时的y坐标
*/
private int yMove;

private LayoutInflater mInflater;

private PopupWindow mPopupWindow;
private int mPopupWindowHeight;
private int mPopupWindowWidth;

private Button mDelBtn;
/**
* 为删除按钮提供一个回调接口
*/
private DelButtonClickListener mListener;

/**
* 当前手指触摸的View
*/
private View mCurrentView;

/**
* 当前手指触摸的位置
*/
private int mCurrentViewPos;

/**
* 必要的一些初始化
*
* @param context
* @param attrs
*/
public QQListView(Context context, AttributeSet attrs) {
super(context, attrs);

mInflater = LayoutInflater.from(context);
touchSlop = ViewConfiguration.get(context).getScaledTouchSlop();

View view = mInflater.inflate(R.layout.delete_btn, null);
mDelBtn = (Button) view.findViewById(R.id.id_item_btn);
mPopupWindow = new PopupWindow(view, LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
/**
* 先调用下measure,否则拿不到宽和高
*/
mPopupWindow.getContentView().measure(0, 0);
mPopupWindowHeight = mPopupWindow.getContentView().getMeasuredHeight();
mPopupWindowWidth = mPopupWindow.getContentView().getMeasuredWidth();
}

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
int action = ev.getAction();
int x = (int) ev.getX();
int y = (int) ev.getY();
switch (action) {

case MotionEvent.ACTION_DOWN:
xDown = x;
yDown = y;
/**
* 如果当前popupWindow显示，则直接隐藏，然后屏蔽ListView的touch事件的下传
*/
if (mPopupWindow.isShowing()) {
dismissPopWindow();
return false;
}
// 获得当前手指按下时的item的位置
mCurrentViewPos = pointToPosition(xDown, yDown);
// 获得当前手指按下时的item
View view = getChildAt(mCurrentViewPos - getFirstVisiblePosition());
mCurrentView = view;
break;
case MotionEvent.ACTION_MOVE:
xMove = x;
yMove = y;
int dx = xMove - xDown;
int dy = yMove - yDown;
/**
* 判断是否是从右到左的滑动
*/
if (xMove < xDown && Math.abs(dx) > touchSlop && Math.abs(dy) < touchSlop) {
// Log.e(TAG, "touchslop = " + touchSlop + " , dx = " + dx +
// " , dy = " + dy);
isSliding = true;
}
break;
}
return super.dispatchTouchEvent(ev);
}

@Override
public boolean onTouchEvent(MotionEvent ev) {
int action = ev.getAction();
/**
* 如果是从右到左的滑动才相应
*/
if (isSliding) {
switch (action) {
case MotionEvent.ACTION_MOVE:

int[] location = new int[2];
// 获得当前item的位置x与y
mCurrentView.getLocationOnScreen(location);
// 设置popupWindow的动画
mPopupWindow.setAnimationStyle(R.style.popwindow_delete_btn_anim_style);
mPopupWindow.update();
mPopupWindow.showAtLocation(mCurrentView, Gravity.LEFT | Gravity.TOP,
location[0] + mCurrentView.getWidth(),
location[1] + mCurrentView.getHeight() / 2 - mPopupWindowHeight / 2);
// 设置删除按钮的回调
mDelBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (mListener != null) {
mListener.clickHappend(mCurrentViewPos);
mPopupWindow.dismiss();
}
}
});
// Log.e(TAG, "mPopupWindow.getHeight()=" + mPopupWindowHeight);

break;
case MotionEvent.ACTION_UP:
isSliding = false;

}
// 相应滑动期间屏幕itemClick事件，避免发生冲突
return true;
}

return super.onTouchEvent(ev);
}

/**
* 隐藏popupWindow
*/
private void dismissPopWindow() {
if (mPopupWindow != null && mPopupWindow.isShowing()) {
mPopupWindow.dismiss();
}
}

public void setDelButtonClickListener(DelButtonClickListener listener) {
mListener = listener;
}

interface DelButtonClickListener {
public void clickHappend(int position);
}

}
2）使用自定义view方法
package com.example.listviewitemslidedeletebtnshow;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.Toast;

import com.example.listviewitemslidedeletebtnshow.QQListView.DelButtonClickListener;

public class MainActivity extends Activity
{
private QQListView mListView;
private ArrayAdapter<String> mAdapter;
private List<String> mDatas;

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

mListView = (QQListView) findViewById(R.id.id_listview);
// 不要直接Arrays.asList
mDatas = new ArrayList<String>(Arrays.asList("HelloWorld", "Welcome", "Java", "Android", "Servlet", "Struts",
"Hibernate", "Spring", "HTML5", "Javascript", "Lucene"));
mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mDatas);
mListView.setAdapter(mAdapter);

mListView.setDelButtonClickListener(new DelButtonClickListener()
{
@Override
public void clickHappend(final int position)
{
Toast.makeText(MainActivity.this, position + " : " + mAdapter.getItem(position), 1).show();
mAdapter.remove(mAdapter.getItem(position));
}
});

mListView.setOnItemClickListener(new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
Toast.makeText(MainActivity.this, position + " : " + mAdapter.getItem(position), 1).show();
}
});
}
}

mAdapter = new AppAdapter();
listView.setAdapter(mAdapter);

// step 1. create a MenuCreator
SwipeMenuCreator creator = new SwipeMenuCreator() {

// set a icon
deleteItem.setIcon(R.drawable.ic_delete);
// add to menu
menu.addMenuItem(deleteItem);
}
};
// set creator
listView.setMenuCreator(creator);

// step 2. listener item click event
listView.setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public void onMenuItemClick(int position, SwipeMenu menu, int index) {
ApplicationInfo item = mAppList.get(position);
switch (index) {
case 0:
// open
open(item);
break;
case 1:
// delete
// delete(item);
mAppList.remove(position);
mAdapter.notifyDataSetChanged();
break;
}
}
});

// set SwipeListener
listView.setOnSwipeListener(new OnSwipeListener() {

@Override

});

// other setting
// listView.setCloseInterpolator(new BounceInterpolator());

// test item long click
listView.setOnItemLongClickListener(new OnItemLongClickListener() {

@Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {

}
}

private void open(ApplicationInfo item) {
// open app
Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);
resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);
resolveIntent.setPackage(item.packageName);
List<ResolveInfo> resolveInfoList = getPackageManager()
.queryIntentActivities(resolveIntent, 0);

}
}

class AppAdapter extends BaseAdapter {

@Override
public int getCount() {

}
}

private int dp2px(int dp) {
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp,
getResources().getDisplayMetrics());
