【问题描述】：
大家好，我有这个在 java 类中制作的自定义视图寻呼机。当我将该 viewpager 放入 xml 并运行程序时，它崩溃了。从堆栈跟踪来看，它看起来好像在错误的位置，但我不知道如何修复它。
这是我的视图寻呼机类
public class MyViewPager extends ViewPager
{
private boolean swipeable;
public MyViewPager(Context context) {
super(context);
}
public MyViewPager (Context context, AttributeSet attrs) {
super(context, attrs);
this.swipeable = true;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (this.swipeable) {
return super.onTouchEvent(event);
}
return false;
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
if (this.swipeable) {
return super.onInterceptTouchEvent(event);
}
return false;
}
public void setSwipeable(boolean swipeable) {
this.swipeable = swipeable;
}
}
这是我的 xml
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/main_TL"
app:tabTextColor="@color/white"
app:tabSelectedTextColor="@color/white"
app:tabMaxWidth="0dp"
app:tabGravity="fill"
app:tabMode="fixed"
app:tabIndicatorColor="@color/white"
app:tabBackground="@color/salmon_main"/>
<com.daprlabs.aaron.zivitApp.Main.Main.MyViewPager
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/main_VP">
</com.daprlabs.aaron.zivitApp.Main.Main.MyViewPager>
这是我的堆栈跟踪：

【问题讨论】：
-
您是否尝试过清理和重建您的项目？ （在
Build下的标签栏中） -
你的层次结构对我来说很奇怪
com.daprlabs.aaron.zivitApp.Main.Main.MyViewPager你能发布视图的层次结构吗？ -
如何获得视图的层次结构？
-
截图你的文件夹结构类似于this
-
@Enzokie 我刚刚添加了屏幕截图
