PopupWindow 属性用来设置视图的位置
主java写
package com.example.popupwindow;
import com.example.popupwindow.R.drawable;
import android.app.Activity;
import android.graphics.drawable.BitmapDrawable;
import android.os.Bundle;
import android.view.Gravity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.ListAdapter;
import android.widget.PopupWindow;
import android.widget.TextView;
public class MainActivity extends Activity {
public PopupWindow pw;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void dian(View v){//点击事件
View view = View.inflate(this, R.layout.popup_window, null);
GridView viewById = (GridView) view.findViewById(R.id.gv);
viewById.setAdapter(new MyActivity());//设置九宫格
//设置冒泡
pw=new PopupWindow(view,
ViewGroup.LayoutParams.MATCH_PARENT,//填充宽度
ViewGroup.LayoutParams.WRAP_CONTENT);//包裹内容填充(内容是View的match填充父窗体,填充父窗体就是包裹内容,包裹内容-->View的填充父窗体--->(两个结合父类的wrap_..)--->GridView的包裹内容)
pw.setBackgroundDrawable(new BitmapDrawable());//可绘制的位图
pw.setFocusable(true);//设置可聚焦的 //显示/消失
// pw.showAsDropDown(v);//指定在控件上的按钮的下方出现
//显示在屏幕下方 (v是按钮v.getparent()是父布局,显示在什么位置,x水平的偏移量,y是垂直的偏移量)
pw.showAtLocation((View) v.getParent(), Gravity.BOTTOM, 0, 0);
}
class MyActivity extends BaseAdapter{
int[] images={
R.drawable.i1,R.drawable.i2,
R.drawable.i3,R.drawable.i4,
R.drawable.i5,R.drawable.i6,
R.drawable.i7,R.drawable.i8,
};
String []names={
"1","2","3","4","5","6","7","8",
};
@Override
public int getCount() {
// TODO Auto-generated method stub
return names.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return names[position];
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
shuju shju=null;
if(convertView==null){
convertView=View.inflate(MainActivity.this, R.layout.item, null);
shju=new shuju();
shju.iv_icon=(ImageView) convertView.findViewById(R.id.iv_icon);
shju.text=(TextView) convertView.findViewById(R.id.text);
convertView.setTag(shju);
}else{
shju=(shuju) convertView.getTag();
}
shju.iv_icon.setImageResource(images[position]);
shju.text.setText(names[position]);
return convertView;
}
class shuju{
ImageView iv_icon;
TextView text;
}
}
}
主xml写
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="冒泡"
android:onClick="dian"
/>
</RelativeLayout>
弹出的布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/back" >//设置了渐变背景
<GridView
android:id="@+id/gv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numColumns="5"
></GridView>
</LinearLayout>
加载布局控件GridView网格布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/iv_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

/>
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"

显示在右下
int[] location = new int[2];
view.getLocationOnScreen(location);
mPw.showAtLocation(view, Gravity.NO_GRAVITY, location[0]+view.getWidth(), location[1]+view.getHeight());
动画

显示在右下也可以用包含自带的点击效果(动画)
// 通过WindowManager获取
mDm = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(mDm);
// System.out.println("width-display :" + dm.widthPixels);
// System.out.println("heigth-display :" + dm.heightPixels);
//设置冒泡
mPw = new PopupWindow(view,
ViewGroup.LayoutParams.WRAP_CONTENT,//填充宽度
ViewGroup.LayoutParams.WRAP_CONTENT);//包裹内容填充(内容是View的match填充父窗体,填充父窗体就是包裹内容,包裹内容-->View的填充父窗体--->(两个结合父类的wrap_..)--->GridView的包裹内容)
mPw.setBackgroundDrawable(new BitmapDrawable());//可绘制的位图
mPw.setFocusable(true);//设置可聚焦的 //显示/消失
lv.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) {
mContent = list.get(i-1).get("content");//一共有几条
delete=i-1;//从集合中删除
mPw.showAsDropDown(view, mDm.widthPixels,0);//他不会把自己挤没
