禁用整个视图树

Question

我正在尝试在布局中显示另一个视图的视图，同时禁用后面的视图......

以下是一些屏幕截图，可以更好地理解我的要求：

问题是我仍然可以点击后视图中的编辑文本字段。

这是我的XML代码：

            android:textColor="@android:color/white"
            android:textSize="20sp" />

    </RelativeLayout>
</RelativeLayout>

在这里我尝试禁用后视图：

parentLayout.setEnabled(false);

这里初始化parentLayout：

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.login_fragment, container, false);
        parentLayout = (RelativeLayout) view;
        initView(view);
        return view;
    }

您不需要使用view.setEnabled（false）。您可以将onTouchListener设置为上层封面，并且在onTouch方法的回调函数中，始终返回true。

在这种情况下，您的触摸事件不会“回退”到后面的视图。
