AlertDialog添加控件 .

在项目开发中，经常用到AlertDialog提示用户信息，简单的Dialog提醒，或者警告信息都很esey的实现， 在dialog进行操作这种实现在开发中也很常用。 今天就做一个简单dialog添加控件的例子。言语不多，直接看例子。

dialog.xml源代码：

<?xml version="1.0" encoding="utf-8"?>

    <!-- dialog layout -->

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical" android:layout_width="fill_parent"

    android:layout_height="wrap_content">

    <LinearLayout android:orientation="horizontal"

        android:layout_width="fill_parent" android:layout_height="wrap_content"

        android:padding="2dip" android:gravity="center">



        <TextView android:width="60dip" android:text="工号："

            android:layout_width="wrap_content" android:layout_height="wrap_content"

            android:typeface="monospace" android:textColor="#FFF" />



        <EditText android:id="@+id/job_number" android:width="180dip"

            android:layout_width="wrap_content" android:layout_height="wrap_content"

            android:typeface="monospace" android:textColor="#FFF" />

    </LinearLayout>



    <LinearLayout android:orientation="horizontal"

        android:layout_width="fill_parent" android:layout_height="wrap_content"

        android:padding="2dip" android:gravity="center">



        <TextView android:width="60dip" android:text="口令："

            android:layout_width="wrap_content" android:layout_height="wrap_content"

            android:typeface="monospace" android:textColor="#FFF" />



        <EditText android:id="@+id/shibboleth" android:width="180dip"

            android:layout_width="wrap_content" android:layout_height="wrap_content"

            android:typeface="monospace" android:textColor="#FFF" />

    </LinearLayout>

</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>

	<!-- dialog layout -->

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

	android:orientation="vertical" android:layout_width="fill_parent"

	android:layout_height="wrap_content">

	<LinearLayout android:orientation="horizontal"

		android:layout_width="fill_parent" android:layout_height="wrap_content"

		android:padding="2dip" android:gravity="center">



		<TextView android:width="60dip" android:text="工号："

			android:layout_width="wrap_content" android:layout_height="wrap_content"

		<EditText android:id="@+id/job_number" android:width="180dip"

			android:layout_width="wrap_content" android:layout_height="wrap_content"

			android:typeface="monospace" android:textColor="#FFF" />

	</LinearLayout>



	<LinearLayout android:orientation="horizontal"

		android:layout_width="fill_parent" android:layout_height="wrap_content"

		android:padding="2dip" android:gravity="center">



		<TextView android:width="60dip" android:text="口令："

			android:layout_width="wrap_content" android:layout_height="wrap_content"

			android:typeface="monospace" android:textColor="#FFF" />



		<EditText android:id="@+id/shibboleth" android:width="180dip"

			android:layout_width="wrap_content" android:layout_height="wrap_content"

			android:typeface="monospace" android:textColor="#FFF" />

	</LinearLayout>

</LinearLayout>

DialogActivity.java源代码：

public class DialogActivity extends Activity {

    ProgressDialog m_Dialog;

    /** Called when the activity is first created. */

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        LayoutInflater inflater = LayoutInflater

        .from(DialogActivity.this);

        // 得到自定义对话框

        final View DialogView = inflater

        // 创建对话框

        AlertDialog alertDialog = new AlertDialog.Builder(DialogActivity.this)

        .setTitle("目标确认")

                        m_Dialog = ProgressDialog.show(DialogActivity.this,

                        "请等待...", "系统正在登录...", true);

                        new Thread()

                        {
                            public void run() {

                                try {
                                    sleep(3000);
                                } catch (Exception e) {

                                    // TODO: handle exception

                                    // 登录结束，取消m_Dialog对话框

                                    m_Dialog.dismiss();

}

显示结果。。如图：
