android 自定义progressbar 样式

在res下创建drawable文件夹，新建文件drawable/progressbar_color.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <!-- 背景  gradient是渐变,corners定义的是圆角 -->
    <item android:id="@android:id/background"
        android:layout_width="wrap_content">
        <shape>
            <corners android:radius="10dp" />

            <solid android:color="#ffffff" />
        </shape>
    </item>
    <!-- 第二条进度条颜色 -->
    <item android:id="@android:id/secondaryProgress">
        <clip>
            <shape>
                <corners android:radius="10dp" />

                <gradient
                    android:angle="90.0"
                    android:centerColor="#aadfdf"
                    android:centerY="0.45"
                    android:endColor="#aadfdf"
                    android:startColor="#aadfdf" />
            </shape>
        </clip>
    </item>
    <!-- 进度条 -->
    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <corners android:radius="10dp" />
                <solid android:color="#00a8a7" />
            </shape>
        </clip>
    </item>

测试程序：

private void showDialog(){
    mDialog = new CommonProgressDialog(this);  

    mDialog.setMessage("正在下载");
    mDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    mDialog.setOnCancelListener(new OnCancelListener() {  

        @Override
        public void onCancel(DialogInterface dialog) {
            // TODO Auto-generated method stub
            //cancel(true);
        }
    });
    mDialog.show();  

    mDialog.setMax(100*1024*1024);
    mDialog.setProgress(65*1024*1024);
}
