public class Add extends Activity{

PopupWindow popUp;
Dialog myDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    setContentView(R.layout.add);

    myDialog = new Dialog(Add.this);
    myDialog.setContentView(R.layout.popup50);
    myDialog.setTitle("Please Pay Attention!");
    myDialog.setCancelable(true);

    //for save
  Button popone = (Button)myDialog.findViewById(R.id.button1);
  popone.setOnClickListener(new OnClickListener()
  {
  public void onClick(View v) 
  {

      myDialog.dismiss();

     }
  });


  //for cancel
  Button poptwo = (Button)myDialog.findViewById(R.id.button2);
  poptwo.setOnClickListener(new OnClickListener()
  {
  public void onClick(View v) 
  {


    Intent CheckProfile = new Intent(Add.this, UserActivity.class);
    startActivity(CheckProfile);
    myDialog.dismiss();


     }
  });


  myDialog.show();


}

这是 XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:background="#00FFFF"
android:layout_width="300dp"
android:layout_height="wrap_content" >

<TextView
    android:id="@+id/popUp_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="30dp"
    android:gravity="center"
    android:textColor="#000000"
    android:text="@string/pop50"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<Button
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_below="@+id/popUp_text"
    android:layout_marginRight="36dp"
    android:layout_marginTop="44dp"
    android:text="Cancel" />

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/button2"
    android:layout_alignBottom="@+id/button2"
    android:layout_marginRight="69dp"
    android:layout_toLeftOf="@+id/button2"
    android:text="  Ok  " />

</RelativeLayout>

我有类似的东西来显示一个可能对你有帮助的关于屏幕：

b.setOnClickListener(new View.OnClickListener() {  
    public void onClick(View v) {
        show_about();              
    }
});

...

private void showAbout() {
    Dialog dialog = new Dialog (context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.about);
    dialog.setCanceledOnTouchOutside(true);
    dialog.show();      
}

xml 位：

  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin" >

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="23dp"
        android:text="An app for the Newcastle Cloud Team"
        android:textAppearance="?android:attr/textAppearanceSmall" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/textView2"
        android:layout_centerHorizontal="true"
        android:src="@drawable/coche3" />

    ...

  </RelativeLayout>

<ImageView
    android:id="@+id/image"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginRight="5dp" />

<TextView
    android:id="@+id/text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#FFF" 
    android:layout_toRightOf="@+id/image"/>/>

 <Button
     android:id="@+id/dialogButtonOK"
     android:layout_width="100px"
     android:layout_height="wrap_content"
     android:layout_below="@+id/image"
     android:layout_centerHorizontal="true"
     android:layout_marginTop="18dp"
     android:text=" Ok " />

将此代码放入按钮事件或您想要的任何内容中

final Dialog dialog = new Dialog(context);
            dialog.setContentView(R.layout.coustom);
            dialog.setTitle("Title...");

            // set the custom dialog components - text, image and button
            TextView text = (TextView) dialog.findViewById(R.id.text);
            text.setText("Android custom dialog ");
            ImageView image = (ImageView) dialog.findViewById(R.id.image);
            image.setImageResource(R.drawable.ic_launcher);

            Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
            // if button is clicked, close the custom dialog
            dialogButton.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    dialog.dismiss();
                }
            });

            dialog.show();

public class PopupforeditActivity extends Activity {


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.alphabetslist);

    callalertDialogueCustom();


} 

   public void callalertDialogueCustom(){

    final Dialog dialog = new Dialog(PopupforeditActivity.this);

    dialog.setContentView(R.layout.popup); // This is my Custom Layout
    dialog.setTitle("This is my custom dialog box");
    dialog.setCancelable(true);
    //there are a lot of settings, for dialog, check them all out!

    //set up text
    TextView text = (TextView) dialog.findViewById(R.id.txt1);
    text.setText("Lots of Hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii");

    EditText edt=(EditText) dialog.findViewById(R.id.edtxtName);
    edt.setText("i am binded this time");

    //set up image view
   /* ImageView img = (ImageView) dialog.findViewById(R.id.ImageView01);

    //set up button
    Button button = (Button) dialog.findViewById(R.id.btnSave);
    button.setOnClickListener(new OnClickListener() {
    @Override
        public void onClick(View v) {

        Toast.makeText(getApplicationContext(), "You clicked on Save",
                Toast.LENGTH_SHORT).show();
        dialog.dismiss();

        }
    });

    Button button1 = (Button) dialog.findViewById(R.id.btnCancel);
    button1.setOnClickListener(new OnClickListener() {
    @Override
        public void onClick(View v) {
         //finish();
        dialog.dismiss();
        }
    });
    //now that the dialog is set up, it's time to show it    
    dialog.show();


}

}

只需调用此callalertDialogueCustom(); 根据您的需要从任何地方获取方法.. 它还将创建自定义对话并为其处理点击事件
