日常开发过程中对于PopupWindown的使用也是比较多的。这里给大家展示一下PopupWindow的使用。

修改activity_main.xml布局：

<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}" > 
 
 <RelativeLayout 
 android:layout_width="match_parent" 
 android:layout_height="50dip" 
 android:background="@android:color/holo_blue_dark"> 
 
 <ImageView 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:layout_centerVertical="true" 
 android:layout_marginLeft="10dip" 
 android:background="@drawable/ic_launcher" /> 
 
 <ImageView 
 android:id="@+id/rl_more" 
 android:layout_width="wrap_content" 
 android:layout_height="match_parent" 
 android:background="@drawable/ability_show_item_bg" 
 android:paddingLeft="15dp" 
 android:paddingRight="5dp" 
 android:layout_alignParentRight="true" 
 android:src="@drawable/actionbar_more_icon" /> 
 
 </RelativeLayout> 
 
</RelativeLayout>

新建popup_window.xml布局文件

<?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:background="@android:color/white" 
 android:gravity="center_horizontal" 
 android:orientation="vertical" > 
 
 <TextView 
 android:id="@+id/settings" 
 android:layout_width="match_parent" 
 android:layout_height="45dp" 
 android:gravity="center" 
 android:padding="12dp" 
 android:text="设置" 
 android:textSize="16sp" /> 
 
 <View 
 android:layout_width="match_parent" 
 android:layout_height="1dp" 
 android:background="#BDBDBD" /> 
 
 <TextView 
 android:id="@+id/about" 
 android:layout_width="match_parent" 
 android:layout_height="45dp" 
 android:gravity="center" 
 android:padding="12dp" 
 android:text="关于" 
 android:textSize="16sp" /> 
 
 <View 
 android:layout_width="match_parent" 
 android:layout_height="1dp" 
 android:background="#BDBDBD" /> 
 
 <TextView 
 android:id="@+id/ability_logout" 
 android:layout_width="match_parent" 
 android:layout_height="45dp" 
 android:gravity="center" 
 android:padding="12dp" 
 android:text="退出" 
 android:textSize="16sp" /> 
 
</LinearLayout>

自定义PopupWindow类PopWindow

package com.syz.mypopupwindow; 
 
import android.app.Activity; 
import android.content.Context; 
import android.graphics.drawable.ColorDrawable; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.ViewGroup.LayoutParams; 
import android.widget.PopupWindow; 
 
/** 
 * <p>Title:PopWindow</p> 
 * <p>Description: 自定义PopupWindow</p> 
 * @author syz 
 * @date 2016-3-14 
 */ 
public class PopWindow extends PopupWindow{ 
 private View conentView; 
 public PopWindow(final Activity context){ 
 LayoutInflater inflater = (LayoutInflater) context 
 .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
 conentView = inflater.inflate(R.layout.popup_window, null); 
 int h = context.getWindowManager().getDefaultDisplay().getHeight(); 
 int w = context.getWindowManager().getDefaultDisplay().getWidth(); 
 // 设置SelectPicPopupWindow的View 
 this.setContentView(conentView); 
 // 设置SelectPicPopupWindow弹出窗体的宽 
 this.setWidth(w / 2 + 40); 
 // 设置SelectPicPopupWindow弹出窗体的高 
 this.setHeight(LayoutParams.WRAP_CONTENT); 
 // 设置SelectPicPopupWindow弹出窗体可点击 
 this.setFocusable(true); 
 this.setOutsideTouchable(true); 
 // 刷新状态 
 this.update(); 
 // 实例化一个ColorDrawable颜色为半透明 
 ColorDrawable dw = new ColorDrawable(0000000000); 
 // 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作 
 this.setBackgroundDrawable(dw); 
 // mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog); 
 // 设置SelectPicPopupWindow弹出窗体动画效果 
 this.setAnimationStyle(R.style.AnimationPreview); 
 
 conentView.findViewById(R.id.about).setOnClickListener(new OnClickListener() { 
 
 @Override 
 public void onClick(View arg0) { 
 //do something you need here 
 PopWindow.this.dismiss(); 
 } 
 }); 
 conentView.findViewById(R.id.ability_logout).setOnClickListener(new OnClickListener() { 
 
 @Override 
 public void onClick(View arg0) { 
 // do something before signing out 
 context.finish(); 
 PopWindow.this.dismiss(); 
 } 
 }); 
 conentView.findViewById(R.id.settings).setOnClickListener(new OnClickListener() { 
 
 @Override 
 public void onClick(View arg0) { 
 // do something you need here 
  
 PopWindow.this.dismiss(); 
 } 
 }); 
 } 
 
 /** 
 * 显示popupWindow 
 * 
 * @param parent 
 */ 
 public void showPopupWindow(View parent) { 
 if (!this.isShowing()) { 
 // 以下拉方式显示popupwindow 
 this.showAsDropDown(parent, parent.getLayoutParams().width / 2, 5); 
 } else { 
 this.dismiss(); 
 } 
 } 
}

添加自定义PopupWindow所需的style

AnimationPreview

<style name="AnimationPreview"> 
 <item name="android:windowEnterAnimation">@anim/fade_in</item> 
 <item name="android:windowExitAnimation">@anim/fade_out</item> 
 </style>

添加style所需的动画

fade_in.xml

<?xml version="1.0" encoding="utf-8"?> 
<!-- 左上角扩大--> 
 <scale xmlns:android="http://schemas.android.com/apk/res/android" 
 android:interpolator="@android:anim/accelerate_decelerate_interpolator" 
 android:fromXScale="0.001" 
 android:toXScale="1.0" 
 android:fromYScale="0.001" 
 android:toYScale="1.0" 
 android:pivotX="100%" 
 android:pivotY="10%" 
 android:duration="200" />

fade_out.xml

<?xml version="1.0" encoding="utf-8"?> 
<!-- 左上角缩小 --> 
 <scale xmlns:android="http://schemas.android.com/apk/res/android" 
 android:interpolator="@android:anim/accelerate_decelerate_interpolator" 
 android:fromXScale="1.0" 
 android:toXScale="0.001" 
 android:fromYScale="1.0" 
 android:toYScale="0.001" 
 android:pivotX="100%" 
 android:pivotY="10%" 
 android:duration="200" />

最后在MainActivity类中使用

package com.syz.mypopupwindow; 
 
import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
 
public class MainActivity extends Activity implements OnClickListener { 
 
 @Override 
 protected void onCreate(Bundle savedInstanceState) { 
 super.onCreate(savedInstanceState); 
 setContentView(R.layout.activity_main); 
 findViewById(R.id.rl_more).setOnClickListener(this); 
 } 
 
 @Override 
 public void onClick(View v) { 
 if(v.getId() == R.id.rl_more){ 
 PopWindow popWindow = new PopWindow(this); 
 popWindow.showPopupWindow(findViewById(R.id.rl_more)); 
 } 
 } 
}
