1.  建立一个my_progress_dialog.xml布局文件

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="200dip"     android:layout_height="200dip" >

<ImageView

android:id="@+id/iv_progressDialog"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerInParent="true"

android:src="@drawable/my_progress_dialog_rotate" />

<TextView

android:id="@+id/tv_progressDialog"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_below="@id/iv_progressDialog"

android:layout_centerHorizontal="true"

android:layout_marginTop="10dip"

android:gravity="center"

android:text="load..." />

</RelativeLayout>

2.在res目录下建立文件anim/my_progress_dialog_rotate_anim.xml,自定义动画

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"     android:shareInterpolator="false" >

<!-- 定义一个MyProgressDialog中imageView转动的动画 -->

<rotate         android:duration="1500"

android:fromDegrees="0"

android:interpolator="@android:anim/linear_interpolator"

android:pivotX="50%"

android:pivotY="50%"

android:repeatCount="-1"

android:repeatMode="restart"

android:startOffset="-1"

android:toDegrees="+360" />

</set>

3.在values的styles.xml中添加Dialog样式

<!-- 自定义loading dialog -->
    <style name="myProgressDialog" parent="android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowBackground">@android:color/white</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

4.自定义一个方法实现Dialog

/**   * 得到自定义的progressDialog

*   * @param context

* @param msg

* @return

*/

public static Dialog createLoadingDialog(Context context, String msg) {

LayoutInflater inflater = LayoutInflater.from(context);

View v = inflater.inflate(R.layout.my_progress_dialog, null);// 得到加载view

ImageView spaceshipImage = (ImageView) v.findViewById(R.id.iv_progressDialog);

TextView tipTextView = (TextView) v.findViewById(R.id.tv_progressDialog);// 提示文字

// 加载动画

Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(context, R.anim.my_progress_dialog_rotate_anim);   // 使用ImageView显示动画   spaceshipImage.startAnimation(hyperspaceJumpAnimation);

tipTextView.setText(msg);// 设置加载信息

Dialog loadingDialog = new Dialog(context, R.style.myProgressDialog);// 创建自定义样式dialog

loadingDialog.setCancelable(false);

loadingDialog .setContentView(v, new LinearLayout.LayoutParams(150, 150));

return loadingDialog;

}
