android - 移动图像按钮后，应用程序崩溃!安卓

Question

因此，我最近开发的应用程序进展顺利，我只是在应用程序后台更新了图像。好了，在我调整图像按钮使其与我制作的图像对齐之前，该应用程序就可以正常工作。在我移动它后，该应用将不再起作用，并且我尝试了所有尝试均未成功。这是 Activity 的xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:background="@drawable/title_screen"
  tools:context=".TitleScreen" >

  <TextView
    android:id="@+id/txtCoins"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:layout_marginRight="18dp"
    android:layout_marginTop="11dp"
    android:text="000"
    android:textAppearance="?android:attr/textAppearanceSmall"
    android:textColor="#f3c50d"
    android:textSize="12sp" />

  <ImageButton
    android:id="@+id/imageBtnPlay"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/txtCoins"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="51dp"
    android:background="@null"
    android:src="@drawable/btn_play" />

   </RelativeLayout>

编辑:这是我的logcat

Answer 1

android.widget.TextView cannot be cast to android.widget.ImageButton

您在 Activity 中转换为错误的类，将 TextView更改为 ImageButton类中的 com.ChonBonStudios.Tidbits.TitleScreen。
