废话不多说了，直接给大家贴代码了。

布局文件xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".DialogActivity" > <Button android:id="@+id/plainDialog" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="普通Dialog" /> <Button android:id="@+id/plainDialogEvent" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Dialog按钮事件集中处理" /> <Button android:id="@+id/inputDialog" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="请输入框" /> <Button android:id="@+id/listDialog" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="列表对话框" /> <Button android:id="@+id/radioDialog" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="单选对话框" /> <Button android:id="@+id/checkboxDialog" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="多选对话框" /> <Button android:id="@+id/diyDialog" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="自定义布局对话框" /> </LinearLayout>

Activity文件：

普通的dialog：

private void plainDialogDemo() { Button plainBtn = (Button) findViewById(R.id.plainDialog); plainBtn.setOnClickListener(new OnClickListener() { public void onClick(View v) { new AlertDialog.Builder(DialogActivity.this) .setTitle("删除") .setMessage("确定删除指定数据") .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(getApplicationContext(), "确定了", Toast.LENGTH_SHORT) .show(); } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }).setCancelable(false).show(); } }); }

效果如下：

输入文本框的dialog：

private void inputDialog() { Button inputBtn = (Button) findViewById(R.id.inputDialog); inputBtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub final EditText et = new EditText(DialogActivity.this); new AlertDialog.Builder(DialogActivity.this) .setTitle("请输入数字") .setView(et) .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub Toast.makeText(getApplicationContext(), et.getText(), Toast.LENGTH_SHORT).show(); } }).setNegativeButton("取消", null) .setCancelable(false).show(); } }); }

效果如下：

列表dialog：

private void listDialogDemo() { Button listBtn = (Button) findViewById(R.id.listDialog); listBtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { final String[] names = { "C罗", "J罗", "H罗" }; new AlertDialog.Builder(DialogActivity.this).setTitle("列表对话框") .setItems(names, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(DialogActivity.this, names[which], Toast.LENGTH_SHORT) .show(); } }).setNegativeButton("取消", null).show(); } }); }

效果如下：

单选dialog：

private void radioDialogDemo() { Button radioButton = (Button) findViewById(R.id.radioDialog); radioButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { final String[] names = { "C罗", "J罗", "H罗" }; new AlertDialog.Builder(DialogActivity.this) .setTitle("列表对话框") .setSingleChoiceItems(names, , new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { selecteName = names[which]; } }) .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(DialogActivity.this, selecteName, Toast.LENGTH_SHORT) .show(); } }).setNegativeButton("取消", null).show(); } }); }

效果如下：

多选dialog：

private void checkDialogDemo() { Button checkBtn = (Button) findViewById(R.id.checkboxDialog); checkBtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { final String[] names = { "C罗", "J罗", "H罗" }; final boolean[] selected = new boolean[] { true, false, true }; new AlertDialog.Builder(DialogActivity.this) .setMultiChoiceItems( names, selected, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { } }) .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { StringBuilder sb = new StringBuilder( "你选择了："); for (int i = ; i < names.length; i++) { if (selected[i]) { sb.append(names[i]); } } Toast.makeText(DialogActivity.this, sb.toString(), ).show(); } }).setNegativeButton("取消", null).show(); } }); }

效果如下：

自定义dialog：

private void customDialogDemo() { final AlertDialog dlg = new AlertDialog.Builder(this).create(); dlg.show(); Window window = dlg.getWindow(); window.setContentView(R.layout.diylayout); ImageButton ok = (ImageButton) window.findViewById(R.id.btnok); ok.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Toast.makeText(getApplicationContext(), "关闭了", Toast.LENGTH_SHORT).show(); dlg.dismiss(); } }); }

自定义布局：

<" encoding="utf-"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <ImageView android:id="@+id/dialogimg" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:src="@drawable/dialog_bg" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@id/dialogimg" android:layout_alignTop="@id/dialogimg" android:layout_marginLeft="dp" android:layout_marginTop="dp" android:text="自定义的dialog" /> <ImageButton android:id="@+id/btnok" android:layout_width="dp" android:layout_height="dp" android:layout_alignRight="@id/dialogimg" android:layout_alignTop="@id/dialogimg" android:layout_marginRight="dp" android:layout_marginTop="dp" android:background="@drawable/close_dialog" /> </RelativeLayout>

效果如：
