搭建直播平台，Android开发之禁止下拉通知栏的方法

搭建直播平台，Android开发之禁止下拉通知栏的方法

思路：在状态栏上覆盖一层透明view，点击时，直接消费掉，禁止继续往下传递，接触不到状态栏，就拉不出来，比较笨的一个办法，但是也挺有效

 

废话说的不少了，上代码把：

 

//禁止下拉
private void UnDropDown() {
    manager = ((WindowManager) getApplicationContext()
            .getSystemService(Context.WINDOW_SERVICE));
    WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();
    localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
    localLayoutParams.gravity = Gravity.TOP;
    localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
            // this is to enable the notification to recieve touch events
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
            // Draws over status bar
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
    localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
    localLayoutParams.height = (int) (50 * getResources()
            .getDisplayMetrics().scaledDensity); //50高度这边我是固定死了，也可以动态获取状态栏高度，然后赋值
    localLayoutParams.format = PixelFormat.TRANSPARENT;
    view = new CustomViewGroup(this);
    manager.addView(view, localLayoutParams);
}

​

CustomViewGroup 代码：

 

import android.content.Context;
import android.util.Log;
import android.view.MotionEvent;
import android.view.ViewGroup;
public class CustomViewGroup extends ViewGroup {
    public CustomViewGroup(Context context) {
        super(context);
    }
    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b) {
    }
    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        //直接消费，不向下传递
        return true;
    }
}

 

 不要忘记销毁

 

@Override
protected void onDestroy() {
    super.onDestroy();
    if (view != null) {
        WindowManager manager = ((WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE));
        manager.removeView(view);
    }
}
