【Android】创建Popwindow弹出菜单的两种方式

方法一的Activity

[java] view plain copy

packagecom.app.test02;
importandroid.app.Activity;
importandroid.os.Bundle;
importandroid.view.Gravity;
importandroid.view.MotionEvent;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.view.View.OnTouchListener;
importandroid.view.ViewGroup.LayoutParams;
importandroid.widget.Button;
importandroid.widget.PopupWindow;
importandroid.widget.Toast;
publicclassPopwindowLeftextendsActivity{
//声明PopupWindow对象的引用
privatePopupWindowpopupWindow;
/**Calledwhentheactivityisfirstcreated.*/
@Override
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_popupwindow_main);
//点击按钮弹出菜单
Buttonpop=(Button)findViewById(R.id.popBtn);
pop.setOnClickListener(popClick);
}
//点击弹出左侧菜单的显示方式
OnClickListenerpopClick=newOnClickListener(){
@Override
publicvoidonClick(Viewv){
//TODOAuto-generatedmethodstub
getPopupWindow();
//这里是位置显示方式,在屏幕的左侧
popupWindow.showAtLocation(v,Gravity.LEFT,0,0);
}
};
/**
*创建PopupWindow
*/
protectedvoidinitPopuptWindow(){
//TODOAuto-generatedmethodstub
//获取自定义布局文件activity_popupwindow_left.xml的视图
ViewpopupWindow_view=getLayoutInflater().inflate(R.layout.activity_popupwindow_left,null,
false);
//创建PopupWindow实例,200,LayoutParams.MATCH_PARENT分别是宽度和高度
popupWindow=newPopupWindow(popupWindow_view,200,LayoutParams.MATCH_PARENT,true);
//设置动画效果
popupWindow.setAnimationStyle(R.style.AnimationFade);
//点击其他地方消失
popupWindow_view.setOnTouchListener(newOnTouchListener(){
@Override
publicbooleanonTouch(Viewv,MotionEventevent){
//TODOAuto-generatedmethodstub
if(popupWindow!=null&&popupWindow.isShowing()){
popupWindow.dismiss();
popupWindow=null;
}
returnfalse;
}
});
}
/***
*获取PopupWindow实例
*/
privatevoidgetPopupWindow(){
if(null!=popupWindow){
popupWindow.dismiss();
return;
}else{
initPopuptWindow();
}
}
}

方法二的Activity

[java] view plain copy

packagecom.app.test02;
importandroid.app.Activity;
importandroid.os.Bundle;
importandroid.view.Gravity;
importandroid.view.MotionEvent;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.view.View.OnTouchListener;
importandroid.view.ViewGroup.LayoutParams;
importandroid.widget.PopupWindow;
publicclassPopwindowLeftNewextendsActivity{
privatePopupWindowpopupWindow;
@Override
protectedvoidonCreate(BundlesavedInstanceState){
//TODOAuto-generatedmethodstub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_popupwindow_main);
findViewById(R.id.popBtn).setOnClickListener(newOnClickListener(){
@Override
publicvoidonClick(Viewv){
//TODOAuto-generatedmethodstub
//获取自定义布局文件activity_popupwindow_left.xml的视图
ViewpopupWindow_view=getLayoutInflater().inflate(R.layout.activity_popupwindow_left,null,false);
//创建PopupWindow实例,200,LayoutParams.MATCH_PARENT分别是宽度和高度
popupWindow=newPopupWindow(popupWindow_view,200,LayoutParams.MATCH_PARENT,true);
//设置动画效果
popupWindow.setAnimationStyle(R.style.AnimationFade);
//这里是位置显示方式,在屏幕的左侧
popupWindow.showAtLocation(v,Gravity.LEFT,0,0);
//点击其他地方消失
popupWindow_view.setOnTouchListener(newOnTouchListener(){
@Override
publicbooleanonTouch(Viewv,MotionEventevent){
//TODOAuto-generatedmethodstub
if(popupWindow!=null&&popupWindow.isShowing()){
popupWindow.dismiss();
popupWindow=null;
}
returnfalse;
}
});
}
});
}
}

弹出动画XML

在res文件夹下，建立anim文件夹。写入如下两个文件。

弹出动画

in_lefttoright.xml
[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<setxmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="500"
android:fromXDelta="-100%"
android:toXDelta="0"/>
</set>

弹回动画

out_righttoleft.xml
[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<setxmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="500"
android:fromXDelta="0"
android:toXDelta="-100%"/>
</set>

动画管理

在styles.xml中，添加如下管理代码。 [html] view plain copy

<stylename="AnimationFade">
<itemname="android:windowEnterAnimation">@anim/in_lefttoright</item>
<itemname="android:windowExitAnimation">@anim/out_righttoleft</item>
