Android新功能，我已按照this tutorial将“图片”按钮添加到我的应用中，但它失败了。

package com.example.rgm;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
import android.widget.Toast;

import com.example.rgm.R;

public class MainActivity extends Activity {

    ImageButton playButton;

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

        addListenerOnButton();

    }

    public void addListenerOnButton() {

        playButton = (ImageButton) findViewById(R.id.playButton);

        // button action
        playButton.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {
               Toast.makeText(MainActivity.this,
                "ImageButton is clicked!", Toast.LENGTH_SHORT).show();
            }
        });
    }
}

这是我的activity_main.xml内容

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="fill"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <ImageButton
        android:id="@+id/playButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="118dp"
        android:background="@style/AppBaseTheme"
        android:contentDescription="@string/play"
        android:src="@drawable/play"
    />

</RelativeLayout>

这是我的资源/文件夹
