我做了一個應用程序，它使用runnable讀取特定類型的短信。 Everyhing正常工作。我收到了短信，從讀狀態移動閱讀，但它崩潰的onResume（），並給予下列錯誤：Android onResume崩潰
Unable to resume activity {com.android.testthread/com.android.testthread.MainActivity}: android.database.StaleDataException: Attempted to access a cursor after it has been closed.
如何解決這個問題？
public class MainActivity extends Activity {
boolean recieved = false;
private TextView text;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text = (TextView) findViewById(R.id.textView1);
Runnable runnable = new Runnable() {
@Override
public void run() {
while (!recieved) {
doFakeWork();
text.post(new Runnable() {
@Override
public void run() {
List<Sms> list = getAllSms();
if (list.size() > 0) {
if (list.get(0).getAddress().equals("Engage") && list.get(0).getFolderName().equals("inbox") && list.get(0).getReadState().equals("0")) {
setReadMessage(list.get(0).getId());
text.setText("Got it");
Toast.makeText(MainActivity.this, list.get(0).getMsg(), Toast.LENGTH_SHORT).show();
recieved = true;
}
}
}
});
}
}
};
new Thread(runnable).start();
}
