适合所有屏幕尺寸

Question

Am I doing it right? I'm trying to make my project that can be used in all different screen sizes, because from the beginning of time I'm creating it using API 17(Nexus One)

<supports-screens
        android:smallScreens="true"
        android:normalScreens="true"
        android:largeScreens="true"
        android:xlargeScreens="true"
        android:anyDensity="true" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/fitnessku"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/AppTheme" >
        <compatible-screens>
            <!-- all small size screens -->
            <screen android:screenSize="small" android:screenDensity="ldpi" />
            <screen android:screenSize="small" android:screenDensity="mdpi" />
            <screen android:screenSize="small" android:screenDensity="hdpi" />
            <screen android:screenSize="small" android:screenDensity="xhdpi" />
            <!-- all normal size screens -->
            <screen android:screenSize="normal" android:screenDensity="ldpi" />
            <screen android:screenSize="normal" android:screenDensity="mdpi" />
            <screen android:screenSize="normal" android:screenDensity="hdpi" />
            <screen android:screenSize="normal" android:screenDensity="xhdpi" />
            <!-- all large size screens -->
            <screen android:screenSize="large" android:screenDensity="ldpi" />
            <screen android:screenSize="large" android:screenDensity="mdpi" />
            <screen android:screenSize="large" android:screenDensity="hdpi" />
            <screen android:screenSize="large" android:screenDensity="xhdpi" />
        </compatible-screens>

You need to create directory for each layout . add these directories to your layout folder to support multiple screen sizes.

• layout-small
• layout-normal
• layout-large
• layout-xlarge
• layout-xxlarge

Don't forget to declare it on manifest file.
