NavDrawer没有触及其他视图

标签： android navigation-drawer ontouchlistener gesturedetector

我想创建一个包含图像的抽屉活动。现在我希望图像视图的父级，即content_main2，它是相对布局，应该监听触摸事件，如滑动和拖动。但它只是接触了。

我的主要活动是导航抽屉活动。

答案 0 :(得分：1)

刚补充，
android:focusableInTouchMode="true"
android:focusable="true"
android:clickable="true"
在content_main2（RelativeLayout）中。
现在一切正常。
