今天介紹一種Android登入對話方塊的實現。
dialog.xml用於設定DialogView

Activity

packagecom.study.android;

 

importandroid.app.Activity;

importandroid.app.AlertDialog;

importandroid.app.ProgressDialog;

importandroid.content.DialogInterface;

importandroid.os.Bundle;

importandroid.view.LayoutInflater;

importandroid.view.View;

 

publicclass Android_DialogActivity extends Activity {

    /** Called when the activity is firstcreated. */

    ProgressDialog p_dialog;

 

    @Override

    public void onCreate(BundlesavedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        AlertDialog dialog = newAlertDialog.Builder(

       Android_DialogActivity.this)

       .setTitle("登入提示")

      .setMessage("是否登入")

     .setPositiveButton("確定", new DialogInterface.OnClickListener() {

      @Override

      public voidonClick(DialogInterface dialog, int which) {

      // TODO Auto-generated method stub

      LayoutInflater factory =LayoutInflater

    .from(Android_DialogActivity.this);

     final View DialogView =factory.inflate(

     R.layout.dialog, null);

    AlertDialog dlg = newAlertDialog.Builder(

    Android_DialogActivity.this)

   .setTitle("登陸框")

   .setView(DialogView)

   .setPositiveButton("確定",

   newDialogInterface.OnClickListener() {

  @Override

  public void onClick(

  DialogInterface dialog,

   int which) {

// TODO Auto-generated method

 // stub

  p_dialog = ProgressDialog

.show(Android_DialogActivity.this,

"請等待",

"正在為您登入...",

true);

newThread() {

publicvoid run() {

try{

sleep(3000);

}catch (Exception e) {

}finally {

p_dialog.dismiss();

}

 }

}.start();

}

                                        })

      .setNegativeButton("取消",

        newDialogInterface.OnClickListener() {

 

         @Override

          public void onClick(

          DialogInterface dialog,

           int which) {

           // TODOAuto-generated method

           // stub

          Android_DialogActivity.this

           .finish();

           }

           }).create();

           dlg.show();

 

                    }

                })

               .setNegativeButton("退出", new DialogInterface.OnClickListener() {

 

                    @Override

                    publicvoid onClick(DialogInterface dialog, int which) {

                        //TODO Auto-generated method stub

                       Android_DialogActivity.this.finish();

                    }

                }).create();

        dialog.show();

    }

 

}
