import android.widget.Button;
import android.widget.TextView;

public class phys extends Activity {

 Vibrator vibr;
 Button but;
 TextView txt;
 int counter = 0;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        vibr = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
        but = (Button)findViewById(R.id.Button01);
        txt = (TextView)findViewById(R.id.txt);
        but.setOnClickListener(clk);
    }

    OnClickListener clk = new OnClickListener(){

  @Override
  public void onClick(View v) {
   // TODO Auto-generated method stub
   txt.setText(Integer.toString(counter));
   //do something else
   vibr.vibrate(500);
   counter++;
  }

    };
}

推荐答案

使用 adb logcat ，DDMS或Eclipse中的DDMS透视图来查看LogCat并检查与应用程序意外停止应用程序关联的堆栈跟踪。

Use adb logcat, DDMS, or the DDMS perspective in Eclipse to look at LogCat and examine the stack trace associated with your " application stopped unexpectedly " error. That will give you more information about where you are going wrong.

我怀疑问题是您缺少 VIBRATE 权限。如果是，请将其添加为 AndroidManifest.xml 文件中< manifest> p>

I suspect the problem is that you are missing the VIBRATE permission. If so, add this as a child of your <manifest> element in your AndroidManifest.xml file:

<uses-permission android:name="android.permission.VIBRATE"/>
