1 让程序竖屏和让程序全屏
<activity android:name=".android"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
//让程序全屏
android:screenOrientation="portrait" //让程序竖屏
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
2 让程序自适应分辨率
<supports-screens
android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:resizeable="true"
android:anyDensity="true"
/>
<uses-sdk android:minSdkVersion="7" />//此值大于等于7
3 按钮的三个状态----做个xml放在drawable文件夹下,在mail里面把button背景指向这个xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_window_focused="false"
android:drawable="@drawable/h2" />
<item android:state_pressed="true"
android:drawable="@drawable/h3" />
<item android:state_focused="true"
android:drawable="@drawable/h3" />
<item
android:drawable="@drawable/h2" />
</selector>
