ImageButton 未打开滑动菜单 Android

Question

所以我想做的是使用 ImageButton 和 onClick 来打开 android 侧边菜单，但我一直收到错误消息。

home.xml（ImageButton 与 onClick 所在的位置）

 <ImageButton
    android:id="@+id/imgViewRefresh4"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="100dp"
    android:visibility="gone"
    android:onClick="click1"
    style="?android:attr/borderlessButtonStyle"
    android:src="@drawable/slide4" />

MainActivity.java（调用 onClick 的地方）

public void click1(){
     mDrawerLayout.openDrawer(mDrawerList);
}

Logcat错误

您必须像这样更改方法才能处理点击

public void click1(View v){
     mDrawerLayout.openDrawer(mDrawerList);
}
