android基礎之Dialog

Builder類中還有一個SetView()方法：

可以在對話框中添加組件

builder.setView(new CheckBox(this));//添加CheckBox

Builder.setMultiChoiceItems(String[]arg0,Boolean[]arg1,OnMultiChoiceClickListener arg3)//添加復選框的方法

Builder.setSingleChoiceItems(String[]arg0,int arg1,OnClickListener arg3)//添加單選框

代碼如下：

package com.example.dialog;

import android.app.Activity;

import android.app.AlertDialog.Builder;

import android.content.DialogInterface;

import android.content.DialogInterface.OnClickListener;

import android.content.DialogInterface.OnMultiChoiceClickListener;

import android.os.Bundle;

public class MainActivity extends Activity {

private Builder builder;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

builder=new Builder(MainActivity.this);

builder.setIcon(android.R.drawable.ic_dialog_info);

builder.setTitle("Dialog");

//builder.setMessage("dialog對話框");

builder.setPositiveButton("yes",new OnClickListener()

{

public void onClick(DialogInterface dialog,int which)

{

}});

builder.setNegativeButton("no",new OnClickListener()

{

public void onClick(DialogInterface dialog,int which)

{

}

}

);

/*builder.setSingleChoiceItems(new String[]{"單選", "單選"},1,new OnClickListener() 

{

public void onClick(DialogInterface dialog,int which)

{

}

}

);

*/

/*

builder.setMultiChoiceItems(new String[]{"多選","多選"},new boolean[]{false,true},new OnMultiChoiceClickListener()

{

public void onClick(DialogInterface dialog,int which,boolean inChecked)

{

}

}

);*/

/*builder.setItems(new String[]{"列表項1","列表項2","列表項3"},new OnClickListener()

{

public void onClick(DialogInterface dialog,int which)

{

}

}

);*/

LayoutInflater inflater=getLayoutInflater();

View layout=inflater.inflate(R.layout.dialog, (ViewGroup)findViewById(R.id.myLayout));

builder.setView(layout);

builder.show();

}

}

在對話框中 除了可以添加組件外 還可以添加布局。

增加一個xml布局文件。

運行如下：
