android - showDialog deprecated. What's the alternative?

Question

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
}
