1.写在前面

Android提供了丰富的Dialog函数，本文介绍最常用的8种对话框的使用方法，包括普通(包含提示消息和按钮)、列表、单选、多选、等待、进度条、编辑、自定义等多种形式，将在第2部分介绍。

有时，我们希望在对话框创建或关闭时完成一些特定的功能，这需要复写Dialog的create()、show()、dismiss()等方法，将在第3部分介绍。

图片示例

2.1 普通Dialog(图1与图2)

public class MainActivity extends Activity \{

@Override

protected void onCreate(Bundle savedInstanceState) \{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity\_main);

Button buttonNormal = (Button) findViewById(R.id.button\_normal);

buttonNormal.setOnClickListener(new View.OnClickListener() \{

@Override

public void onClick(View v) \{

showNormalDialog();

\});

private void showNormalDialog()\{

/\* @setIcon 设置对话框图标

\* @setTitle 设置对话框标题

\* @setMessage 设置对话框消息提示

\* setXXX方法返回Dialog对象，因此可以链式设置属性

\*/

final AlertDialog.Builder normalDialog =

new AlertDialog.Builder(MainActivity.this);

normalDialog.setIcon(R.drawable.icon\_dialog);

normalDialog.setTitle("我是一个普通Dialog")

normalDialog.setMessage("你要点击哪一个按钮呢?");

normalDialog.setPositiveButton("确定",

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

//...To-do

\});

normalDialog.setNegativeButton("关闭",

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

//...To-do

\});

// 显示

normalDialog.show();

3个按钮

/\* @setNeutralButton 设置中间的按钮

\* 若只需一个按钮，仅设置 setPositiveButton 即可

\*/

private void showMultiBtnDialog()\{

AlertDialog.Builder normalDialog =

new AlertDialog.Builder(MainActivity.this);

normalDialog.setIcon(R.drawable.icon\_dialog);

normalDialog.setTitle("我是一个普通Dialog").setMessage("你要点击哪一个按钮呢?");

normalDialog.setPositiveButton("按钮1",

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

// ...To-do

\});

normalDialog.setNeutralButton("按钮2",

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

// ...To-do

\});

normalDialog.setNegativeButton("按钮3", new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

// ...To-do

\});

// 创建实例并显示

normalDialog.show();

2.2 列表Dialog(图3)

private void showListDialog() \{

final String\[\] items = \{ "我是1","我是2","我是3","我是4" \};

AlertDialog.Builder listDialog =

new AlertDialog.Builder(MainActivity.this);

listDialog.setTitle("我是一个列表Dialog");

listDialog.setItems(items, new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

// which 下标从0开始

// ...To-do

Toast.makeText(MainActivity.this,

"你点击了" + items\[which\],

Toast.LENGTH\_SHORT).show();

\});

listDialog.show();

2.3 单选Dialog(图4)

int yourChoice;

private void showSingleChoiceDialog()\{

final String\[\] items = \{ "我是1","我是2","我是3","我是4" \};

yourChoice = -1;

AlertDialog.Builder singleChoiceDialog =

new AlertDialog.Builder(MainActivity.this);

singleChoiceDialog.setTitle("我是一个单选Dialog");

// 第二个参数是默认选项，此处设置为0

singleChoiceDialog.setSingleChoiceItems(items, 0,

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

yourChoice = which;

\});

singleChoiceDialog.setPositiveButton("确定",

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

if (yourChoice != -1) \{

Toast.makeText(MainActivity.this,

"你选择了" + items\[yourChoice\],

Toast.LENGTH\_SHORT).show();

\});

singleChoiceDialog.show();

2.4 多选Dialog(图5)

ArrayList yourChoices = new ArrayList<>();

private void showMultiChoiceDialog() \{

final String\[\] items = \{ "我是1","我是2","我是3","我是4" \};

// 设置默认选中的选项，全为false默认均未选中

final boolean initChoiceSets\[\]=\{false,false,false,false\};

yourChoices.clear();

AlertDialog.Builder multiChoiceDialog =

new AlertDialog.Builder(MainActivity.this);

multiChoiceDialog.setTitle("我是一个多选Dialog");

multiChoiceDialog.setMultiChoiceItems(items, initChoiceSets,

new DialogInterface.OnMultiChoiceClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which,

boolean isChecked) \{

if (isChecked) \{

yourChoices.add(which);

\} else \{

yourChoices.remove(which);

\});

multiChoiceDialog.setPositiveButton("确定",

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

int size = yourChoices.size();

String str = "";

for (int i = 0; i < size; i++) \{

str += items\[yourChoices.get(i)\] + " ";

Toast.makeText(MainActivity.this,

"你选中了" + str,

Toast.LENGTH\_SHORT).show();

\});

multiChoiceDialog.show();

2.5 等待Dialog(图6)

private void showWaitingDialog() \{

/\* 等待Dialog具有屏蔽其他控件的交互能力

\* @setCancelable 为使屏幕不可点击，设置为不可取消(false)

\* 下载等事件完成后，主动调用函数关闭该Dialog

\*/

ProgressDialog waitingDialog=

new ProgressDialog(MainActivity.this);

waitingDialog.setTitle("我是一个等待Dialog");

waitingDialog.setMessage("等待中...");

waitingDialog.setIndeterminate(true);

waitingDialog.setCancelable(false);

waitingDialog.show();

2.6 进度条Dialog(图7)

private void showProgressDialog() \{

/\* @setProgress 设置初始进度

\* @setProgressStyle 设置样式(水平进度条)

\* @setMax 设置进度最大值

\*/

final int MAX\_PROGRESS = 100;

final ProgressDialog progressDialog =

new ProgressDialog(MainActivity.this);

progressDialog.setProgress(0);

progressDialog.setTitle("我是一个进度条Dialog");

progressDialog.setProgressStyle(ProgressDialog.STYLE\_HORIZONTAL);

progressDialog.setMax(MAX\_PROGRESS);

progressDialog.show();

/\* 模拟进度增加的过程

\* 新开一个线程，每个100ms，进度增加1

\*/

new Thread(new Runnable() \{

@Override

public void run() \{

int progress= 0;

while (progress < MAX\_PROGRESS)\{

try \{

Thread.sleep(100);

progress++;

progressDialog.setProgress(progress);

\} catch (InterruptedException e)\{

e.printStackTrace();

// 进度达到最大值后，窗口消失

progressDialog.cancel();

\}).start();

2.7 编辑Dialog(图8)

private void showInputDialog() \{

/\*@setView 装入一个EditView

\*/

final EditText editText = new EditText(MainActivity.this);

AlertDialog.Builder inputDialog =

new AlertDialog.Builder(MainActivity.this);

inputDialog.setTitle("我是一个输入Dialog").setView(editText);

inputDialog.setPositiveButton("确定",

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

Toast.makeText(MainActivity.this,

editText.getText().toString(),

Toast.LENGTH\_SHORT).show();

\}).show();

2.8 自定义Dialog(图9)

android:orientation="vertical"

android:layout\_width="match\_parent"

android:layout\_height="match\_parent">

android:id="@+id/edit\_text"

android:layout\_width="match\_parent"

android:layout\_height="wrap\_content"

private void showCustomizeDialog() \{

/\* @setView 装入自定义View ==> R.layout.dialog\_customize

\* 由于dialog\_customize.xml只放置了一个EditView，因此和图8一样

\* dialog\_customize.xml可自定义更复杂的View

\*/

AlertDialog.Builder customizeDialog =

new AlertDialog.Builder(MainActivity.this);

final View dialogView = LayoutInflater.from(MainActivity.this)

.inflate(R.layout.dialog\_customize,null);

customizeDialog.setTitle("我是一个自定义Dialog");

customizeDialog.setView(dialogView);

customizeDialog.setPositiveButton("确定",

new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

// 获取EditView中的输入内容

EditText edit\_text =

(EditText) dialogView.findViewById(R.id.edit\_text);

Toast.makeText(MainActivity.this,

edit\_text.getText().toString(),

Toast.LENGTH\_SHORT).show();

\});

customizeDialog.show();

3.复写回调函数

/\* 复写Builder的create和show函数，可以在Dialog显示前实现必要设置

\* 例如初始化列表、默认选项等

\* @create 第一次创建时调用

\* @show 每次显示时调用

\*/

private void showListDialog() \{

final String\[\] items = \{ "我是1","我是2","我是3","我是4" \};

AlertDialog.Builder listDialog =

new AlertDialog.Builder(MainActivity.this)\{

@Override

public AlertDialog create() \{

items\[0\] = "我是No.1";

return super.create();

@Override

public AlertDialog show() \{

items\[1\] = "我是No.2";

return super.show();

\};

listDialog.setTitle("我是一个列表Dialog");

listDialog.setItems(items, new DialogInterface.OnClickListener() \{

@Override

public void onClick(DialogInterface dialog, int which) \{

// ...To-do

\});

/\* @setOnDismissListener Dialog销毁时调用

\* @setOnCancelListener Dialog关闭时调用

\*/

listDialog.setOnDismissListener(new DialogInterface.OnDismissListener() \{

public void onDismiss(DialogInterface dialog) \{

Toast.makeText(getApplicationContext(),

"Dialog被销毁了",

Toast.LENGTH\_SHORT).show();

\});

listDialog.show();
