老式水平样式(比较粗)style="@android:style/Widget.ProgressBar.Horizontal"

新式水平样式(比较美观)style="?android:attr/progressBarStyleHorizontal"

@android:style/Widget.ProgressBar.Horizontal

--->

<itemname="progressDrawable">@drawable/progress_horizontal</item>

--->

<layer-listxmlns:android="http://schemas.android.com/apk/res/android">

Handlerhandler=newHandler(){

@Override

public void handleMessage(Message msg) {

if(bar.getProgress() == 100){

bar.setProgress(0);

}else{

bar.setProgress(bar.getProgress()+1);

}

handler.sendEmptyMessageDelayed(0,100);

}

};

@Override

protected voidonCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

bar= (ProgressBar) findViewById(R.id.mypb);

handler.sendEmptyMessage(0);

}

//应用:

<ProgressBar

android:layout_marginTop="10dp"

android:layout_width="300dp"

android:layout_height="96dp"

style="@android:style/Widget.ProgressBar.Horizontal"

android:progressDrawable="@drawable/newstyle"

android:max="100"

android:id="@+id/mypb"

/>

默认样式style="@android:style/Widget.ProgressBar"

更改:style="@android:style/Widget.ProgressBar"

//该文件在F:\adt\adt-bundle-windows-x86_64-20140702\sdk\platforms\android-20\data\res\drawable中打开

<itemname="indeterminateDrawable">@drawable/progress_medium_white</item>

如下:

<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"

android:drawable="@drawable/spinner_white_48"

android:pivotX="50%"

android:pivotY="50%"

android:framesCount="12"

android:frameDuration="100" />

将 android:drawable改为自定义图片

--->

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

android:drawable="@drawable/loading_32dp"

android:pivotX="50%"

android:pivotY="50%"

/>

//应用

<ProgressBar

android:layout_marginTop="10dp"

android:layout_width="match_parent"

android:layout_height="wrap_content"

style="@android:style/Widget.ProgressBar"

android:indeterminateDrawable="@drawable/circle_layout"

android:indeterminateDuration="1000"

/>
