悬浮框的显示以及隐藏,有点类似与mediaController

public void show(int timeout) {

		if (!isshow) {
			if (pauseBtn != null) {
				pauseBtn.requestFocus();
			}
			showTopLayout();
			showBootomLayout();
			isshow = true;
		}
	}
 
/**显示头部*/
private void showTopLayout() {
		LayoutInflater inflater = LayoutInflater.from(this);
		textLayout = (LinearLayout) inflater.inflate(R.layout.textview, null);
		WindowManager.LayoutParams p = new WindowManager.LayoutParams();
		p.gravity = Gravity.TOP;
		p.width = mdisPlayWidth;
		p.height = LayoutParams.WRAP_CONTENT;
		p.x = 0;
		p.y = 0;
		p.format = PixelFormat.TRANSLUCENT;
		p.type = WindowManager.LayoutParams.TYPE_APPLICATION;
		p.token = null;
		// /悬浮框没有按键响应,也不接受触摸响应
		p.flags |= WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE;
		p.flags |= WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
		mwindowManager = (WindowManager) this
				.getSystemService(Context.WINDOW_SERVICE);
		mwindowManager.addView(textLayout, p);

	}
/**显示底部*/

private void showBootomLayout() {
		LayoutInflater inflater = LayoutInflater.from(this);
		controllerLayout = (LinearLayout) inflater.inflate(
				R.layout.media_controller, null);
		setControllerClick();
		WindowManager.LayoutParams p = new WindowManager.LayoutParams();
		p.gravity = Gravity.TOP;
		p.width = mdisPlayWidth;
		p.height = LayoutParams.WRAP_CONTENT;
		p.x = 0;
		p.y = mdisPlayHeight - p.height;
		p.format = PixelFormat.TRANSLUCENT;
		p.type = WindowManager.LayoutParams.TYPE_APPLICATION;
		p.token = null;
		// /悬浮框可以获得焦点触发事件,并且其他键盘按键也可以相应
		p.flags |= WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM;
		p.flags |= WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
		WindowManager windowManager = (WindowManager) this
				.getSystemService(Context.WINDOW_SERVICE);
		windowManager.addView(controllerLayout, p);
	}

 

private void hide() {
		if (controllerLayout != null && isshow == true) {
			isshow = false;
			// if not add this codes ,so throw error
			// android.view.WindowLeaked: Activity org.doubango.imsdroid.
			// Main has leaked window android.widget.TextView@40753348 that was
			// originally added here

			// reason:在没有关闭对话框的时候你把activity给finish,所以造成了这样的结果
			mwindowManager.removeView(controllerLayout);
			mwindowManager.removeView(textLayout);
			controllerLayout = null;
			textLayout = null;

		}

	}
