Java editText setOnFocusChangeListener出错

试图通过使用setOnFocusChangeListener

mMessageBox.setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        // TODO Auto-generated method stub

    }
});

但当我在onCreate函数中使用此函数时，eclipse会给出如下错误

Multiple markers at this line
    - The method setOnFocusChangeListener(View.OnFocusChangeListener) in the type View is not applicable for the arguments (new 
     OnFocusChangeListener(){})
    - OnFocusChangeListener cannot be resolved to a type

是不是因为我在清单文件中使用了最小的sdk？清单文件中的我的sdk选项为

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="17" />

编译器已经说过了

new View.OnFocusChangeListener() {
...
}

重点放在查看上
