我从我的 sqlite 数据库中获取一些文本并将其放在一个变量中：

opis = c.getString(11);

光标在我的应用程序的其余部分工作正常。现在我调用另一个有意图的活动并将字符串发送给它：

Intent opis = new Intent(getApplicationContext(), Popup_opis.class);
opis.putExtra("poslatOpis", opis);
startActivity(opis);

在那个类中，我将该字符串放入另一个字符串中，然后将该文本设置为 TextView。当我在该 TextView 中仅使用单词“text”调用它时，该弹出活动工作正常。现在，这是该活动：

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：

Intent opis = new Intent(getApplicationContext(), Popup_opis.class);
opis.putExtra("poslatOpis", opis);

您将您的opis意图放入您的意图附加内容中，在打包时创建无限递归。为意图和poslatOpis.

theIntent和 theString都被命名为 opis。您可能正在打包意图。而是将字符串打包为额外的。

// Change
opis = c.getString(11);
// to
opisString = c.getString(11);

// and change
opis.putExtra("poslatOpis", opis);
// to
opis.putExtra("poslatOpis", opisString);
