Android自定义PopupWindow实现的Menu(TabMenu)
用过UCWEB-Android版的人都应该对其特殊的menu有印象,把menu做成Tab-Menu(支持分页的Menu),可以容纳比Android传统的menu更丰富的内容(Android的menu超过6项则缩略在[更多]里),本文参考网上的例子,对例子进行简化以及封装,使其作为一个复合控件融入自己的framework。
先来看看本文程序运行的效果:
TabMenu本身就是一个PopupWindow,PopupWindow上面放了两个GridView,第一个GridView就是分页标签,位于PopupWindow的顶部,第二个GridView是菜单,位于PopupWindow的主体。为了实现PopupWindow的弹出/退出的动画效果,本文使用了以下代码:
在工程的res文件夹里添加anim子目录,再新建文件popup_enter.xml:
Java代码
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="1000" />
<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="1000" />
</set>
新建文件popup_exit.xml:
Java代码
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromYDelta="0" android:toYDelta="100%p" android:duration="1000" />
<alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="1000" />
</set>
在工程的values文件夹里新建文件popup_animation.xml:
Java代码
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="PopupAnimation" parent="android:Animation">
<item name="android:windowEnterAnimation">@anim/popup_enter</item>
<item name="android:windowExitAnimation">@anim/popup_exit</item>
</style>
</resources>
main.xml的源码如下:
Java代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01"
android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView android:id="@+id/TextView01" android:layout_height="wrap_content"
android:layout_width="fill_parent" android:text="扩展Menu"></TextView>
</LinearLayout>
TabMenu的封装类TabMenu.java的源码如下:
Java代码
package com.iaiai.activity;
import android.content.Context;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.PopupWindow;
import android.widget.TextView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.LinearLayout.LayoutParams;
