Is there something else that should be called?

showDialog(TIME_DIALOG_ID);

It's in this tutorial but says deprecated in Eclipse.

来自http://developer.android.com/reference/android/app/Activity.html

public final void showDialog (int id) 在 API 级别 1 中添加

此方法在 API 级别 13 中已弃用。请改用带有 FragmentManager 的新 DialogFragment 类;这也可以通过 Android 兼容包在旧平台上使用。

不带任何参数的简单版 showDialog(int, Bundle)。只需使用空参数调用 showDialog(int, Bundle)。

为什么

  • 显示对话框窗口的片段,浮动在其活动窗口的顶部。该片段包含一个 Dialog 对象,它会根据片段的状态适当地显示该对象。对话框的控制(决定何时显示、隐藏、关闭它)应该通过这里的 API 来完成,而不是直接调用对话框。
  • 这是一个很好的讨论 Android DialogFragment vs Dialog
  • 另一个很好的讨论 DialogFragment 优于 AlertDialog

怎么解决?

From Activity#showDialog(int):

This method is deprecated.
Use the new DialogFragment class with FragmentManager instead; this is also available on older platforms through the Android compatibility package.

要显示对话框,可以使用以下代码。这是为了显示一个带有多个复选框的简单 AlertDialog 框:

AlertDialog.Builder alertDialog= new AlertDialog.Builder(MainActivity.this); .
            alertDialog.setTitle("this is a dialog box ");
            alertDialog.setPositiveButton("ok", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getBaseContext(),"ok ive wrote this 'ok' here" ,Toast.LENGTH_SHORT).show();

                }
            });
            alertDialog.setNegativeButton("cancel", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                        Toast.makeText(getBaseContext(), "cancel ' comment same as ok'", Toast.LENGTH_SHORT).show();


                }
            });
            alertDialog.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getBaseContext(), items[which] +(isChecked?"clicked'again i've wrrten this click'":"unchecked"),Toast.LENGTH_SHORT).show();

                }
            });
            alertDialog.show();

标题

而如果您使用 showDialog 函数根据传递的参数显示不同的对话框或任何内容,您可以创建一个 self 函数并可以在该onClickListener()函数下调用它。就像是:

 public CharSequence[] items={"google","Apple","Kaye"};
public boolean[] checkedItems=new boolean[items.length];
Button bt;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    bt=(Button) findViewById(R.id.bt);
    bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            display(0);             
        }       
    });
}

并在函数定义中添加上面给出的对话框代码。

这段代码对我有用。易于修复,但可能不是首选方式。

public void onClick (View v) {
    createdDialog(0).show(); // Instead of showDialog(0);
}

protected Dialog createdDialog(int id) {
    // Your code
}
