单击时如何从原始按钮播放声音按钮？我刚刚创建了一个带id的按钮button1,但无论我写的代码是什么,都是错的.

import android.media.MediaPlayer;

public class BasicScreenActivity extends Activity {

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

    Button one = (Button)this.findViewById(R.id.button1);
    MediaPlayer = mp;
    mp = MediaPlayer.create(this, R.raw.soho);
    zero.setOnCliclListener(new View.OnClickListener() )

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.basic_screen, menu);
        return true;
    }



}

我正在尝试将新的AdMob广告添加到我的第一个应用程序中,我设法以正确的方式安排代码,但我遇到了问题:

第一个问题是我的广告ID ca-app-pub-61413779example正在获得多个错误:ca无法解析为变量,ba无法解析为变量,int类型的文字 61413779超出范围.

第二个问题是R.id. mainLayout,这是mainLayout,我不明白.

 protected void onCreate(Bundle savedInstanceState) {        
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_basic_screen);


     // Create the adView
        adView = new AdView(this, AdSize.BANNER, ca-app-pub-61413779example);

        // Lookup your LinearLayout assuming it's been given
        // the attribute android:id="@+id/mainLayout"
        LinearLayout layout = (LinearLayout)findViewById(R.id.mainLayout);


        // Add the adView to it
        layout.addView(adView);
        adView.loadAd(new AdRequest());

        // Initiate a generic request to load it with an ad
        adView.loadAd(new AdRequest());
