直播平台源码，针对消息对话框的实际应用效果
首先是设计布局文件 activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
 
    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="打开普通对话框"
        android:textSize="20sp"/>
    <Button
        android:id="@+id/btn2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="打开输入对话框"
        android:textSize="20sp"/>
 
</LinearLayout>

设计登录对话框的布局文件login.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
 
    <TextView
        android:id="@+id/user"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="用户名"
        android:textSize="18sp"/>
    <EditText
        android:id="@+id/ed1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="18sp"/>
    <TextView
        android:id="@+id/password"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="密码"
        android:textSize="18sp"/>
    <EditText
        android:id="@+id/ed2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="18sp"/>
 
</LinearLayout>

设计控制文件 MainActivity.java

package com.example.example3_5;
 
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.Toast;
 
public class MainActivity extends AppCompatActivity {
    
    
    ProgressDialog mydialog;
    Button btn1, btn2;
    LinearLayout login;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    
    
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn1 = (Button) findViewById(R.id.btn1);
        btn2 = (Button) findViewById(R.id.btn2);
        btn1.setOnClickListener(new mClick());
        btn2.setOnClickListener(new mClick());
    }
 
    class mClick implements View.OnClickListener {
    
    
        Builder dialog = new AlertDialog.Builder(MainActivity.this);
 
        public void onClick(View arg0) {
    
    
            if (arg0 == btn1) {
    
    
                dialog.setTitle("警告");
                //dialog.setIcon(R.drawable.icon1);
                dialog.setMessage("你的操作会导致信息泄露");
                dialog.setPositiveButton("'确定", new okClick());
                dialog.create();
                dialog.show();
            } else if (arg0 == btn2) {
    
    
                login = (LinearLayout) getLayoutInflater().inflate(R.layout.login, null);
                dialog.setTitle("登陆").setMessage("请输入用户名和密码").setView(login);
                dialog.setPositiveButton("确定", new loginClick());
                dialog.setNegativeButton("退出", new exitClick());
                //dialog.setIcon(R.drawable.icon2);
                dialog.create();
                dialog.show();
            }
 
        }
    }
 
 
    class okClick implements DialogInterface.OnClickListener {
    
    
        public void onClick(DialogInterface dialog, int which) {
    
    
            dialog.cancel();
        }
 
    }
 
    class loginClick implements DialogInterface.OnClickListener {
    
    
        EditText txt;
 
        @Override
 
        public void onClick(DialogInterface dialog, int which) {
    
    
            txt = (EditText) login.findViewById(R.id.ed2);
            if ((txt.getText().toString()).equals("admin")) {
    
    
                Toast.makeText(getApplicationContext(), "登陆成功", Toast.LENGTH_SHORT).show();
            } else
                Toast.makeText(getApplicationContext(), "密码错误", Toast.LENGTH_SHORT).show();
            dialog.dismiss();
        }
    }
 
    class exitClick implements DialogInterface.OnClickListener {
    
    
        public void onClick(DialogInterface dialog, int which) {
    
    
            MainActivity.this.finish();
        }
    }
}
