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，当我单击该按钮时，我收到 KeyDisplatchTimedOut 错误，这意外地停止了我的应用程序。

这是我的日志猫 -

这就是我调用该活动的方式 -

活动1.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);
                    }
                });

对话框.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();

}
}

但不是执行 for 循环并将数组初始化为private String[] items = {"Warrior","Archer","Wizard"};，而是显示了对话框，我没有收到该错误。这里可能有什么问题？

提前致谢。

我认为您正在单击从 sqlite 过程中检索数据中的按钮已完成。因此，您必须等到该过程完成。它更好地用于AsyncTask从SQLite. 有关更多详细信息，请参阅此线程。
