Question

我正在尝试从SQLite表中的列中检索值并将其存储在数组中。我必须通过单击按钮从另一个活动开始该活动。但不幸的是，当我点击该按钮时，我收到KeyDisplatchTimedOut错误，这意外地停止了我的应用程序。

这是我的logcat -

这就是我调用该活动的方式 -

activity1.java：

alert_menu = (Button) findViewById(R.id.alert_menu);
            alert_menu.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    Intent i = new Intent(settings.this,Dialog.class);
                        startActivity(i);
                    }
                });

Dialog.java：

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_dup);

for(int i =1;i<=info.getrowcountofpersons();i++) 
{
    items[i-1]=info.getPersonList(i); //this method will return each person name and will be stored in items[] array
    System.out.println("The list items are:"+items[i-1]); 
    Toast.makeText(getApplicationContext(), items[i-1], Toast.LENGTH_LONG).show();

}
}

但是不是为了循环，而是将数组初始化为private String[] items = {"Warrior","Archer","Wizard"};，而是显示对话框，我没有收到该错误。这可能是什么问题？

提前致谢。

我认为您是在完成sqlite进程检索数据时单击按钮。所以你必须等到这个过程完成。最好使用AsyncTask从SQLite检索数据。有关更多详细信息，请参阅this主题。
