Android-自己定义PopupWindow
2014年5月12日
PopupWindow在应用中应该是随处可见的，非经常常使用到，比方在旧版本号的微信其中就用到下拉的PopupWindow。那是自己定义的。新版微信5.2的ActionBar，有人已经模仿了它，但微信详细是使用了ActionBar还是其它的笔者倒是不太清楚。本篇博客主要介绍怎样自己定义一个PopupWindow来供自己在开发应用时使用。
由于笔者近期在开发一款应用时用到这个知识点，所以自己实现了相似新版微信的效果。
效果图例如以下：
首先从布局開始
/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="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:text="任务系统"
android:textColor="@color/lightgray"
android:textSize="18sp" />
</LinearLayout> <LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"

以上各自是主页面和两个popupWindow布局
以下自己定义两个PopupWindow，自己封装自己想要的PopuoWindow。这里仅仅是给出演示样例
/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; /**
* 自己定义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弹出窗口的宽
this.setWidth(w / 2 + 50);
// 设置SelectPicPopupWindow弹出窗口的高
this.setHeight(LayoutParams.WRAP_CONTENT);
// 设置SelectPicPopupWindow弹出窗口可点击
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键和其它地方使其消失,设置了这个才干触发OnDismisslistener ，设置其它控件变化等操作
this.setBackgroundDrawable(dw);
// mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
// 设置SelectPicPopupWindow弹出窗口动画效果
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弹出窗口的宽
this.setWidth(w / 2 + 50);
// 设置SelectPicPopupWindow弹出窗口的高
this.setHeight(LayoutParams.WRAP_CONTENT);
// 设置SelectPicPopupWindow弹出窗口可点击
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键和其它地方使其消失,设置了这个才干触发OnDismisslistener 。设置其它控件变化等操作
this.setBackgroundDrawable(dw);
// mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
// 设置SelectPicPopupWindow弹出窗口动画效果
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。详细能够下载源代码參考。
