关闭应用程序后数小时后TextViews消失

Question

我正在创建一个待办事项应用。当我关闭应用程序并在几小时后重新打开应用程序时，我可以看到我的文本视图正在保存，但是当您在关闭应用程序几个小时后重新打开应用程序时，它们会消失。关于问题是什么的任何想法？

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_to_do_main);
    setResult(RESULT_CANCELED);
    layout = (LinearLayout) findViewById(R.id.main);
    if (savedInstanceState != null) {
        int counter = PreferenceManager.getDefaultSharedPreferences(this).getInt("key2", 0);
        Log.i("counter on create", Integer.toString(counter));
        for (int i = 0; i < counter; i++) {
            layout.addView(createToDo(PreferenceManager.getDefaultSharedPreferences(this).getString(Integer.toString(i), "")), i);
        }
    }
}

protected void onPause() {
    super.onPause();
    SharedPreferences sharedPreferencesSettings2 = this.getSharedPreferences("PREFERENCE2", MODE_PRIVATE);
    SharedPreferences.Editor editor2 = sharedPreferencesSettings2.edit();
    editor2.putInt("key2", 0);
    editor2.commit();
}

protected void onResume() {
    super.onResume();
    layout = (LinearLayout) findViewById(R.id.main);
    SharedPreferences prefs2 = this.getSharedPreferences("PREFERENCE2", MODE_PRIVATE);
    int counter = prefs2.getInt("key2", 0);
    SharedPreferences prefs = this.getSharedPreferences("PREFERENCE", MODE_PRIVATE);
    for (int i = 0; i < counter; i++) {
        layout.addView(createToDo(prefs.getString(Integer.toString(i), "")));
            textList.add(prefs.getString(Integer.toString(i), ""));
    }
}

protected void onDestroy() {
    super.onDestroy();
    int counter = 0;
    SharedPreferences.Editor editor1 = getSharedPreferences("PREFERENCE", MODE_PRIVATE).edit();
    for (String t: textList) {
        editor1.putString(Integer.toString(counter), t).commit();
        counter++;
    }
    editor1.commit();
    SharedPreferences sharedPreferencesSettings2 = this.getSharedPreferences("PREFERENCE2", MODE_PRIVATE);
    SharedPreferences.Editor editor2 = sharedPreferencesSettings2.edit();
    editor2.putInt("key2", counter);
    editor2.commit();
}

private TextView createToDo(String subject) {
    final TextView todo = new TextView(this);
    final LinearLayout layout = (LinearLayout) findViewById(R.id.main);
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT , 180);
    todo.setLayoutParams(params);

                    layout.removeView(todo);
                }
            })
                    .start();
        }
    });
    return todo;
