这篇博客介绍了如何在Android中创建一个包含EditText的AlertDialog，通过显示一个包含输入框的对话框，允许用户输入密码或其他文本信息。

AlertDialog.Builder dialog = new AlertDialog.Builder(DeviceSetting.this);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout layout = (LinearLayout)inflater.inflate(R.layout.wifidialog, null);
dialog.setView(layout);
passwdet = (EditText)layout.findViewById(R.id.wifipasswd);
dialog.setTitle("请输入密码");
dialog.setPositiveButton("确定", new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
String passwd = passwdet.getText().toString();
}
});
dialog.setNegativeButton("取消", new DialogInterface.OnClickListener() {

public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});

dialog.show();

wifidialog.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
>
<EditText
android:id = "@+id/wifipasswd"
android:layout_width = "fill_parent"
android:layout_height = "wrap_content"
android:password="true"
android:gravity = "center"
/>

</LinearLayout>
