设计登录对话框----Android篇

    之前用过c#设计过登录对话框，现在介绍Android登录对话框的实现

    新建项目，敲击代码：

   

dialog.xml用于设置DialogView

Activity

package com.study.android;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;

public class Android_DialogActivity extends Activity {
	/** Called when the activity is first created. */
	ProgressDialog p_dialog;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		AlertDialog dialog = new AlertDialog.Builder(
				Android_DialogActivity.this)
				.setTitle("登录提示")
				.setMessage("是否登录")
				.setPositiveButton("确定", new DialogInterface.OnClickListener() {

					@Override
					public void onClick(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 = new AlertDialog.Builder(
								Android_DialogActivity.this)
								.setTitle("登陆框")
								.setView(DialogView)
								.setPositiveButton("确定",
										new DialogInterface.OnClickListener() {

											@Override
											public void onClick(
													DialogInterface dialog,
													int which) {
												// TODO Auto-generated method
												// stub
												p_dialog = ProgressDialog
														.show(Android_DialogActivity.this,
																"请等待",
																"正在为您登录...",
																true);
												new Thread() {
													public void run() {
														try {
															sleep(3000);
														} catch (Exception e) {
															e.printStackTrace();
														} finally {
															p_dialog.dismiss();
														}
													}
												}.start();
											}
										})
								.setNegativeButton("取消",
										new DialogInterface.OnClickListener() {

											@Override
											public void onClick(
													DialogInterface dialog,
													int which) {
												// TODO Auto-generated method
												// stub
												Android_DialogActivity.this
														.finish();
											}
										}).create();
						dlg.show();

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

					@Override
					public void onClick(DialogInterface dialog, int which) {
						// TODO Auto-generated method stub
						Android_DialogActivity.this.finish();
					}
				}).create();
		dialog.show();
	}

}

可以看到界面图。
