Question

当我调用我的func从我的数据库中删除一行时：

public void deleteRow(int rowId) {
     getWritableDatabase().delete(DatabaseHelper.orderTable, "id="+rowId,null);

我在logcat中收到很多错误消息：

06-02 16:32:14.356: E/WindowManager(2770): Activity com.Sagi.MyOrders.FindOrder has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@44f50540 that was originally added here

我找了一个打开的光标或数据库，但我找不到任何东西。函数返回后，有：

finish();

这是我的alertDialog创建者：

private void alert_editlist(final int id) {
        // TODO Auto-generated method stub
        final CharSequence[] items = {"Edit", "Delete"};

        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("What do you want to do?");
        builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int item) {
                if (items[item]=="Edit") {
                }
                else if(items[item]=="Delete"){
                   finish();
                }
                finish();
            }
        });
        AlertDialog alert = builder.create();
        alert.show();
    }

谢谢你!!!

您关闭了一个包含dismiss();

的对话框

将finish();更改为dismiss()（在此之前插入删除方法调用），您应该会获得更好的结果。
