<activity android:name="MainActivity" android:theme="@style/Theme.Wallpaper"  ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity>

Activity的配置如上。。重点就是加了一个样式。。。网页有CSS/DIV ,android有样式和主题

android:theme="@style/Theme.Wallpaper"

res/values/styles.xml代码如下

<?xml version="1.0" encoding="utf-8"?><resources>      <style name="Theme.Wallpaper" parent="android:style/Theme.Wallpaper">        <item name="android:colorForeground">#FF0099</item>    </style></resources>

main.xml代码如下

<?xml version="1.0" encoding="utf-8"?><TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/text"    android:layout_width="match_parent" android:layout_height="match_parent"    android:gravity="center_vertical|center_horizontal"    android:text="sun6223508@gmail.com"/>

MainActivity.java代码如下

package com.test.activity;import java.io.IOException;import android.app.Activity;import android.app.WallpaperManager;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.graphics.Color;import android.graphics.Matrix;import android.graphics.PorterDuff;import android.graphics.drawable.BitmapDrawable;import android.graphics.drawable.Drawable;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup.LayoutParams;import android.widget.Button;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.ImageView.ScaleType;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {// Be sure to call the super class.super.onCreate(savedInstanceState);// See res/layout/wallpaper_2.xml for this// view layout definition, which is being set here as// the content of our screen.setContentView(R.layout.main);}}
