Android在弹窗不消失的情况下依然能响应外部事件

1,dialog的方式

public class OffenDestDialog extends Dialog {

    private Context context;

    public OffenDestDialog(@NonNull Context context) {
        super(context);
        this.context = context;
    }


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
         requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.dialog_offen_dest);
        setCanceledOnTouchOutside(false);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);
        initView();
    }

    private void initView() {

    }

    @Override
    public void show() {
        super.show();
        getWindow().setDimAmount(0);//设置背景透明
        getWindow().setDimAmount(0);
        WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
        layoutParams.width = context.getResources().getDisplayMetrics().widthPixels / 3;
        layoutParams.height = context.getResources().getDisplayMetrics().heightPixels / 4 * 3;
        layoutParams.gravity = Gravity.TOP | Gravity.LEFT;
        layoutParams.x = 100;
        layoutParams.y = 100;
        getWindow().getDecorView().setPadding(0, 0, 0, 0);
        getWindow().setAttributes(layoutParams);
    }

2通过WindowManager添加一个自定义布局

 OffenDestDialog offenDestDialog = new OffenDestDialog(getActivity());
        WindowManager wm = getActivity().getWindowManager();
        int width = getActivity().getResources().getDisplayMetrics().widthPixels / 3;
        int heigh = getActivity().getResources().getDisplayMetrics().heightPixels / 4 * 3;
        WindowManager.LayoutParams param= new WindowManager.LayoutParams(width,heigh);
        param.width = width;
        param.height = heigh;
        param.gravity = Gravity.TOP | Gravity.LEFT;
        param.y = Utils.dp2px(100);
        param.x = Utils.dp2px(100);
        param.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL;
        param.format = PixelFormat.RGBA_8888;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            param.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
        } else {
            param.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
        }
        wm.addView(offenDestDialog,param);
