华为手机有虚拟按钮，根据以下设置方法可以进行隐藏控制
/**
* 隐藏虚拟按键，并且全屏
*/
protected void hideBottomUIMenu(Context context){
if(hasNavBar(context)) {
//隐藏虚拟按键，并且全屏
if (Build.VERSION.SDK_INT > && Build.VERSION.SDK_INT < ) { // lower api
View v = this.getWindow().getDecorView();
v.setSystemUiVisibility(View.GONE);
} else if (Build.VERSION.SDK_INT >= ) {
//for new api versions.
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
// | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE;
decorView.setSystemUiVisibility(uiOptions);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
}
} /**
* 检查是否存在虚拟按键栏
* @param context
* @return
*/
public static boolean hasNavBar(Context context) {
Resources res = context.getResources();
int resourceId = res.getIdentifier("config_showNavigationBar", "bool", "android");
if (resourceId != ) {
boolean hasNav = res.getBoolean(resourceId);
// check override flag
String sNavBarOverride = getNavBarOverride();
if ("".equals(sNavBarOverride)) {
hasNav = false;
} else if ("".equals(sNavBarOverride)) {
hasNav = true;
}
return hasNav;
} else { // fallback
return !ViewConfiguration.get(context).hasPermanentMenuKey();
}
} /**
* 判断虚拟按键栏是否重写
* @return
*/
private static String getNavBarOverride() {
String sNavBarOverride = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
try {
Class c = Class.forName("android.os.SystemProperties");
Method m = c.getDeclaredMethod("get", String.class);
m.setAccessible(true);
sNavBarOverride = (String) m.invoke(null, "qemu.hw.mainkeys");
} catch (Throwable e) {
}
}
return sNavBarOverride;
}
按钮隐藏前先进行判断手机是否有虚拟按钮，如果不进行判断，在没有虚拟按钮的手机会报错。
全屏隐藏标题栏和状态栏的代码为：
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
设置屏幕持续高亮的代码为：
getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
