Android Textview 不更新

Question

大家。我正在尝试为 Android 制作一款基本的大亨游戏我正在尝试使用计时器每 5 秒增加一次 TextView 的值，但是 textview 没有更新。到目前为止，这是我的代码:

public class Town extends Activity implements OnClickListener {
Timer timer;
TimerTask task;
TextView goldTV;
TextView woodTV;
TextView foodTV;
TextView stoneTV;
TextView cashTV;
int gold = 20;
int wood = 20;
int food = 20;
int stone = 20;
int cash = 200;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_town);
    goldTV = (TextView) findViewById(R.id.textView1);
    woodTV = (TextView) findViewById(R.id.TextView01);
    foodTV = (TextView) findViewById(R.id.TextView02);
    stoneTV = (TextView) findViewById(R.id.TextView03);
    cashTV = (TextView) findViewById(R.id.TextView04);
    timer = new Timer();
    task = new TimerTask() {

        @Override
        public void run() {
            gold++;
            goldTV.setText(gold);
            try {
                this.wait(2000);
            }
            catch (InterruptedException e){
            }
        }

    };
}
@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub

}

Answer 1

在您的run() 方法中

@Override
public void run() {
          gold++;
          goldTV.setText(gold);

          try {
                this.wait(2000);
          }
          catch (InterruptedException e){

          }
}

您正在调用 setText(int resId) 而不是 setText(CharSequence c);

要显示实际的整数 gold，将其从 int 转换为 String

String goldStr = String.valueOf(gold);

goldTV.setText(goldStr);
