我正面临给定的问题。

在 Galaxy s2 上一切正常，在 noname android 2.3（手机和 7' 平板电脑）上 - 一切正常。但是 Galaxy tab2 和 note2 给出了这个错误。

这是堆栈跟踪：

btn_copy.xml：

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_pressed="true" android:drawable="@drawable/btn_copy_clicked" /> <!-- pressed -->
  <item android:drawable="@drawable/btn_copy_normal" /> <!-- default -->
</selector>

btn_copy_clicked 和 btn_copy_normal 存在于 ldpi、mdpi、hdpi 和 xhdpi 文件夹中。

错误发生在以下行：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_main);

这是按钮的XML部分

<ImageButton
    android:id="@+id/button_copy"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:layout_below="@+id/edit_to"
    android:layout_marginTop="8dp"
    android:background="@android:color/transparent"
    android:src="@drawable/btn_copy" />

怎么了？

尝试在普通的“drawable”文件夹中移动 btn_copy_clicked 和 btn_copy_normal

requestWindowFeature(Window.FEATURE_NO_TITLE)

不再适用于Android 3.0及更高版本。您必须使用ActionbarSherlock库与 3.0 之前的版本兼容
