Android-自定义PopupWindow
2014年5月12日
PopupWindow在应用中应该是随处可见的，很常用到，比如在旧版本的微信当中就用到下拉的PopupWindow，那是自定义的。新版微信5.2的ActionBar，有人已经模仿了它，但微信具体是使用了ActionBar还是其他的笔者倒是不太清楚，本篇博客主要介绍如何自定义一个PopupWindow来供自己在开发应用时使用。因为笔者最近在开发一款应用时用到这个知识点，所以自己实现了类似新版微信的效果。

效果图如下：
首先从布局开始
/14_CustomPopupWindow/res/layout/activity_swipe.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/animation_layout_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/abc_ab_bottom_solid_dark_holo"
android:padding="12dip" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:gravity="center"
android:orientation="horizontal" >
<ImageView
android:layout_width="30dp"
android:layout_height="30dp"
android:src=http://www.mamicode.com/"@drawable/ic_launcher" />>
/14_CustomPopupWindow/res/layout/add_popup_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

<?xml version="1.0" encoding="utf-8"?>

以上分别是主页面和两个popupWindow布局下面自定义两个PopupWindow，自己封装自己想要的PopuoWindow，这里只是给出示例
/14_CustomPopupWindow/src/com/wwj/popupwindow/AddPopWindow.java
package com.wwj.popupwindow;
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.LinearLayout;
import android.widget.PopupWindow;
/**
* 自定义popupWindow
*
* @author wwj

*/
public class AddPopWindow extends PopupWindow {
private View conentView;
public AddPopWindow(final Activity context) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
conentView = inflater.inflate(R.layout.add_popup_dialog, 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 + 50);
// 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);
LinearLayout addTaskLayout = (LinearLayout) conentView
.findViewById(R.id.add_task_layout);
LinearLayout teamMemberLayout = (LinearLayout) conentView
.findViewById(R.id.team_member_layout);
addTaskLayout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
AddPopWindow.this.dismiss();
}
});
teamMemberLayout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
AddPopWindow.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, 18);
} else {
this.dismiss();
}
}
}
/14_CustomPopupWindow/src/com/wwj/popupwindow/MorePopWindow.java
package com.wwj.popupwindow;
import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.PopupWindow;
public class MorePopWindow extends PopupWindow {
private View conentView;
public MorePopWindow(final Activity context) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
conentView = inflater.inflate(R.layout.more_popup_dialog, 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 + 50);
// 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);
}
public void showPopupWindow(View parent) {
if (!this.isShowing()) {
this.showAsDropDown(parent, parent.getLayoutParams().width / 2, 18);
} else {
this.dismiss();
}
}
}
上面用到一个动画样式效果：
/14_CustomPopupWindow/res/values/styles.xml
<style name="AnimationPreview">
<item name="android:windowEnterAnimation">@anim/fade_in</item>
<item name="android:windowExitAnimation">@anim/fade_out</item>
</style>用到两个动画资源
/14_CustomPopupWindow/res/anim/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" />
/14_CustomPopupWindow/res/anim/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" />
/14_CustomPopupWindow/src/com/wwj/popupwindow/MainActivity.java
package com.wwj.popupwindow;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity implements OnClickListener{
private Button setButton;
private Button addButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_swipe);
setButton = (Button) findViewById(R.id.btnSet);
addButton = (Button) findViewById(R.id.btnAdd);
setButton.setOnClickListener(this);
addButton.setOnClickListener(this);;
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnSet:
MorePopWindow morePopWindow = new MorePopWindow(MainActivity.this);
morePopWindow.showPopupWindow(setButton);
break;
case R.id.btnSearch:
break;
case R.id.btnAdd:
AddPopWindow addPopWindow = new AddPopWindow(MainActivity.this);
addPopWindow.showPopupWindow(addButton);
break;
default:
break;
}
}
}
以上是代码实现，具体可以下载源码参考。
