Android 中PopupWindow使用-白红宇

Android 中PopupWindow使用。

PopupWindow会阻塞对话框，要在外部线程或者 PopupWindow本身做退出才行。

mypopWindow.xml的Layout设计如下。

                
<?xml version=
"1.0"
encoding=
"utf-8"
?>
<LinearLayout xmlns:android=
"http://schemas.android.com/apk/res/android"
    
android:layout_width=
"fill_parent"
    
android:layout_height=
"fill_parent"
    
android:background=
"#259"
    
android:orientation=
"vertical"
>
    
<TextView
        
android:id=
"@+id/textView1"
        
android:layout_width=
"wrap_content"
        
android:layout_height=
"wrap_content"
        
android:text=
"Here is Pop Window"
/>
    
<Button
        
android:id=
"@+id/button1"
        
android:layout_width=
"wrap_content"
        
android:layout_height=
"wrap_content"
        
android:text=
"OK"
/>
    
<Button
        
android:id=
"@+id/button2"
        
android:layout_width=
"wrap_content"
        
android:layout_height=
"wrap_content"
        
android:text=
"Cancle"
/>
</LinearLayout>
        
      

MainActivity.java文件。

在MainActivity的Button按钮单击，然后显示PopupWindow。

                
private
void
showPopWindow(Context context, View parent)
    
{       
        
LayoutInflater inflater = (LayoutInflater)              
                
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);     
        
final
View vPopWindow=inflater.inflate(R.layout.mypopwindow, 
null
, 
false
);  
        
//宽300 高300            
        
final
PopupWindow popWindow = 
new
PopupWindow(vPopWindow,
300
,
300
,
true
);
        
Button okButton = (Button)vPopWindow.findViewById(R.id.button1);
        
okButton.setOnClickListener(
new
View.OnClickListener() { 
            
            
@Override
            
public
void
onClick(View v) { 
                
// TODO Auto-generated method stub
                
Toast.makeText(MainActivity.
this
, 
"You click OK"
, Toast.LENGTH_SHORT).show();
            
}
        
});
        
        
Button cancleButton = (Button)vPopWindow.findViewById(R.id.button2);
        
cancleButton.setOnClickListener(
new
View.OnClickListener() { 
            
            
@Override
            
public
void
onClick(View v) { 
                
// TODO Auto-generated method stub
                
popWindow.dismiss(); 
//Close the Pop Window
            
}
        
});
        
        
popWindow.showAtLocation(parent, Gravity.CENTER, 
0
, 
0
);
        
        
    
}
        
      

效果图如下：最后显示是剧中的，这里我只是截取了部分图片。

单击Ok按钮显示You click OK信息。单击取消，则关闭PopupWindow.
