我希望从对话框中单击"确定"按钮时我的计时仪开始...我不能。直到对话框打开时，我才能成功启动我的计时仪。然后，当我单击"确定"按钮时间时...

感谢您的帮助...我开始编码。

我的代码：

    import android.app.Activity;
    import android.app.Dialog;
    import android.os.Bundle;
    import android.os.SystemClock;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.Chronometer;
    import android.widget.TextView;

public class ActivityOne extends Activity implements OnClickListener {
private Chronometer myChronometer;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.timerlayout);
    myChronometer = (Chronometer) findViewById(R.id.chronometer);
    Button buttonStart = (Button) findViewById(R.id.startButton);
    Button buttonStop = (Button) findViewById(R.id.pauseButton);
    Button buttonReset = (Button) findViewById(R.id.resetButton);

    buttonStart.setOnClickListener(this);
    buttonStop.setOnClickListener(this);
    buttonReset.setOnClickListener(this);


final Dialog dialog = new Dialog(ActivityOne.this, R.style.dialogchrono);
dialog.setContentView(R.layout.dialogchrono);
dialog.setTitle("Titre");
TextView txt = (TextView) dialog.findViewById(R.id.textView4);
TextView txt1 = (TextView) dialog.findViewById(R.id.textView1);
TextView txt2 = (TextView) dialog.findViewById(R.id.textView2);
TextView txt3 = (TextView) dialog.findViewById(R.id.textView3);
txt1.setText("Texte1");
txt2.setText("Texte2");
txt3.setText("Texte3");
txt.setText("Texte");
    Button dismissButton = (Button) dialog.findViewById(R.id.button);
dismissButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        dialog.dismiss();
        }
});
        dialog.show();
}
@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.startButton:
            myChronometer.start();
            break;
        case R.id.pauseButton:
            myChronometer.stop();
            break;
        case R.id.resetButton:
            myChronometer.setBase(SystemClock.elapsedRealtime());
            break;
    }
}
}

    case R.id.startButton:
            myChronometer.setBase(SystemClock.elapsedRealtime());
            myChronometer.start();
            break;
