    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="30dp"
                android:layout_height="30dp"
                android:src="@drawable/ic_launcher" />

            <TextView
                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"
            android:layout_alignParentRight="true"
            android:gravity="center"
            android:orientation="horizontal" >

            <Button
                android:id="@+id/btnSearch"
                android:layout_width="30dp"
                android:layout_height="30dp"
                android:layout_marginRight="20dip"
                android:background="@drawable/actionbar_search_icon"
                android:visibility="gone" />

            <Button
                android:id="@+id/btnAdd"
                android:layout_width="30dp"
                android:layout_height="30dp"
                android:layout_marginRight="20dip"
                android:background="@drawable/actionbar_add_icon" />

            <Button
                android:id="@+id/btnSet"
                android:layout_width="30dp"
                android:layout_height="30dp"
                android:background="@drawable/actionbar_more_icon" />
        </LinearLayout>
    </RelativeLayout>

        </LinearLayout>
    </LinearLayout>

</RelativeLayout>

    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.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import android.widget.PopupWindow;

/**

 */
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"
