onResume（）更新TextView

我将从添加

super.onResume();

@Overrideprotected void onResume(){    super.onResume();    // The rest}

我还将删除该内容：

    DepotDBUtils utils = new DepotDBUtils(this);    int itemcount = utils.countItems(this);    TextView tv = (TextView)findViewById(R.id.counter);    tv.setText(tv.getText()+" "+itemcount);

from

onCreate
