[英]Error while updating textview on popup window on Android
我有一個簡單的應用程序,每次單擊按鈕時都會更新數字。 這對正常的活動非常有效。
但是,現在我制作了一個彈出窗口,我想在里面做同樣的事情,但是當點擊彈出窗口內的按鈕時,我收到錯誤:
android.content.res.Resources$NotFoundException: String resource ID #0x1
當我嘗試更新彈出窗口內的 TextView 時發生錯誤
這是我的簡單代碼,它再次在正常活動上完美運行:
public class PopActivity extends Activity {
private WorkOutClass the_workout_class = new WorkOutClass();
private TextView repTextField, setsTextField;
private Button den_knappen;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pop);
repTextField = (TextView) findViewById(R.id.repetitionID);
setsTextField = (TextView) findViewById(R.id.setsID);
den_knappen = (Button) findViewById(R.id.buttonID);
repTextField.setText("" + the_workout_class.getReps());
setsTextField.setText(""+ the_workout_class.getSets());
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels;
int height = dm.heightPixels;
getWindow().setLayout((int)(width*.8), (int)(height*.7));
WindowManager.LayoutParams params = getWindow().getAttributes();
params.gravity = Gravity.CENTER;
params.x = 0;
params.y = 20;
getWindow().setAttributes(params);
den_knappen.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
the_workout_class.increaseReps();
repTextField.setText(the_workout_class.getReps()); // Normally this works perfectly, but here i get ERROR
setsTextField.setText(the_workout_class.getReps()); // Normally this works perfectly, but here i get ERROR
}
});
}}
有人可以幫我嗎?
您的方法getReps()
返回整數值,因此您必須設置如下文本
repTextField.setText(String.valueFrom(the_workout_class.getReps()));
setsTextField.setText(String.valueFrom(the_workout_class.getReps()));
