调用onResume方法时报错

Question

public class Scores extends Activity {

TextView tvPoints;
TextView tvRecord;

int record = 0;
int points = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    tvPoints = (TextView) findViewById(R.id.tvPoints);
    tvRecord = (TextView) findViewById(R.id.tvRecord);

    points = getIntent().getIntExtra("points", 0);
    record = getIntent().getIntExtra("record", 0);
}

@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();

    tvPoints.setText("Points: "+points);
    tvRecord.setText("Record: "+record);
}
}

代码，在使用onResume方法时报出NullPointerException错误。

你的布局setContentView在哪加载的？如果只是没贴出来，那就去找tvPoints和tvRecord什么时候被置空了。
