Android沉浸式状态栏的实现

 沉浸式状态栏需要Android4.4以上版本才支持

第一种方式：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
			// 透明状态栏
			getWindow().addFlags(
					WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
			// 透明导航栏
			getWindow().addFlags(
					WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
			getWindow().getDecorView().setSystemUiVisibility(
					View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
							| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
			// 设置颜色
			getWindow().getDecorView().setBackground(
					new ColorDrawable(Color.RED));
			// 设置高度
			getWindow().getDecorView().setPadding(0, Util.dip2px(mContext, 30),
					0, 0);
		}

 第二种方式：

public class FitSystemWindowRelativeLayout extends RelativeLayout {

	private int insetsBottom = 0;

	public FitSystemWindowRelativeLayout(Context context) {
		this(context, null);
	}

	public FitSystemWindowRelativeLayout(Context context, AttributeSet attrs) {
		this(context, attrs, 0);
	}

	public FitSystemWindowRelativeLayout(Context context, AttributeSet attrs,
			int defStyle) {
		super(context, attrs, defStyle);
		setFitsSystemWindows(true);
	}

	@Override
	protected boolean fitSystemWindows(Rect insets) {
		insets.top = 0;
		return super.fitSystemWindows(insets);
	}

	public int getInsetsBottom() {
		return insetsBottom;
	}

}

Activity的使用方式

@Override
	protected void onCreate(Bundle savedInstanceState) {
		Log.d(TAG, this.getClass().getSimpleName() + " onCreate() invoked!!");
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		AppManager.getAppManager().addActivity(this);
	}

	@Override
	public void setContentView(int layoutResID) {
		FitSystemWindowRelativeLayout baseLayout = new FitSystemWindowRelativeLayout(this);
		ViewGroup rootView = (ViewGroup) getWindow().getDecorView();
		rootView.removeAllViews();
		mLayoutInflater = LayoutInflater.from(this);
		mLayoutInflater.inflate(layoutResID, rootView);
		super.setContentView(baseLayout);
	}
