Android开发之自定义dialog的实现（源代码分享）

       使用系统自带的dialog如果不能满足我们日常开发的需求，那就得自己构建custom dialog，特别是对于一个app来说，统一的样式风格会给人一种舒服的感觉，所以dialog的样式 、色调一般都要和app主题符合，这篇博客主要介绍两种方式来自定义dialog。

MainActivity的代码

package com.example.e01_consumerdialog;

import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {
     private Button button;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button=(Button)this.findViewById(R.id.button1);
        button.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
			  AlertDialog.Builder builder=new Builder(MainActivity.this);
			  builder.setTitle("登陆界面");
			  View view=LayoutInflater.from(MainActivity.this).inflate(R.layout.dialog, null);
			  builder.setView(view);//设置自定义布局view
			  builder.setPositiveButton("确认", new OnClickListener() {
				
				@Override
				public void onClick(DialogInterface arg0, int arg1) {
					// TODO Auto-generated method stub
					
				}
			});
			  builder.setNegativeButton("取消",new OnClickListener() {
				
				@Override
				public void onClick(DialogInterface arg0, int arg1) {
					// TODO Auto-generated method stub
					
				}
			});
			  builder.show();
			}
		});
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
        
    }
    
}

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

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText1"
        android:layout_marginTop="27dp"
        android:layout_toLeftOf="@+id/editText1"
        android:text="密  码：" />

    <EditText
        android:id="@+id/editText2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/textView2"
        android:layout_alignBottom="@+id/textView2"
        android:layout_alignLeft="@+id/editText1"
        android:layout_alignRight="@+id/editText1"
        android:ems="10"
        android:inputType="textPassword" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/textView1"
        android:layout_alignBottom="@+id/textView1"
        android:layout_toRightOf="@+id/textView1"
        android:ems="10" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:text="用户名：" />
    
</RelativeLayout>

Tip: If you want a custom dialog, you can instead display an Activity as a dialog instead of using the DialogAPIs. Simply create an activity and set its theme to Theme.Holo.Dialog in the <activity> manifest element:

<activity android:theme="@android:style/Theme.Holo.Dialog" >

That‘s it. The activity now displays in a dialog window instead of fullscreen.
