android分辨率较多

480*800 --------------hdpi

540*960 --------------xhdpi

如果是Tablet的话

drawable-sw600dp 7寸平板

drawable-w720dp 大于7寸的平板

drawable-large 适合所有平板

google官方推荐手机和平板的判断标准:

public static boolean isTablet() {

		return (RingCentralApp.getContextRC().getResources().getConfiguration().screenLayout
				& Configuration.SCREENLAYOUT_SIZE_MASK) >= Configuration.SCREENLAYOUT_SIZE_LARGE;
	}

android获取手机本身的信息

<span style="white-space:pre">		</span>DisplayMetrics dm = new DisplayMetrics();
		getWindowManager().getDefaultDisplay().getMetrics(dm);
		RCMConstants.screenWidth = dm.widthPixels;
		RCMConstants.density = dm.density;

android按钮的几种状态:

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/btn_call_disabled" android:state_enabled="false" />
    <item android:drawable="@drawable/btn_call_pressed" android:state_pressed="true" />
    <item android:drawable="@drawable/btn_call_nor" android:state_focused="true" />
    <item android:drawable="@drawable/btn_call_nor" />
</selector>
