我从我的sqlite数据库中获取了一些文本并将其放在变量中:
opis = c.getString(11);
Cursor在我的应用程序的其余部分正常工作。 现在我调用另一个有意图的活动并发送字符串:
Intent opis = new Intent(getApplicationContext(), Popup_opis.class);
opis.putExtra("poslatOpis", opis);
startActivity(opis);
在该类中,我将该字符串放在另一个字符串中,然后将该文本设置为TextView。当我在TextView中使用单词“text”调用它时,弹出活动工作正常。现在,这是活动:
public class Popup_opis extends Activity{
TextView opis;
String poslatOpis, primljenOpis;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.popup_opis);
Bundle extras = getIntent().getExtras();
if(extras !=null) {
primljenOpis = extras.getString("poslatOpis");
}
initVariables();
}
private void initVariables() {
Typeface tv = Typeface.createFromAsset(getAssets(), "ARIALN.TTF");
opis = (TextView) findViewById(R.id.tvOpis);
opis.setTypeface(tv);
opis.setText(primljenOpis);
}
}
这是LogCat:

我做错了什么?
答案 0 :(得分:6)
Intent opis = new Intent(getApplicationContext(), Popup_opis.class);
opis.putExtra("poslatOpis", opis);
您将opis
意图置于意图附加内容中,在分区时创建无限递归。为intent和poslatOpis
使用不同的变量名称。
答案 1 :(得分:1)
Intent
和String
都命名为opis。你可能正在意图分配意图。将字符串包裹为额外的字符串。
答案 2 :(得分:1)
// Change
opis = c.getString(11);
// to
opisString = c.getString(11);
// and change
opis.putExtra("poslatOpis", opis);
// to
opis.putExtra("poslatOpis", opisString);
