android logo的loading,自定义加载进度条loading的几种方式

1.

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

activity中用法

public class AfActivity extends Activity implements OnClickListener {

private ImageView imageView;

private Button moveButton;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

imageView = (ImageView) findViewById(R.id.iv_imagemove);

moveButton = (Button) findViewById(R.id.move);

moveButton.setOnClickListener(this);

}

public void onClick(View v) {

// 得到配置文件中的背景文件28

imageView.setBackgroundResource(R.drawable.progress_m);

AnimationDrawable animationDrawable = (AnimationDrawable) imageView

.getBackground();

animationDrawable.start();

}

}

3.一张图片

android:drawable="@drawable/spinner_black_16"

android:pivotX="50%"

android:pivotY="50%"

android:fromDegrees="0"

android:toDegrees="360" />

4.多张图标水平进度条

style="?android:attr/progressBarStyleHorizontal" 定义ProgressBar为水平类型

5.水平进度条

android:id="@android:id/background"

android:drawable="@drawable/footer_navigation"/>

android:angle="270"

android:centerColor="#FFFF8C00"

android:centerY="0.75"

android:endColor="#FF6611"

android:startColor="#FFFFD980" />

6.新浪图标加载

android:clipOrientation="vertical"

android:gravity="bottom" >

android:angle="90"

android:centerColor="#55000000"

android:centerX="0.75"

android:endColor="#55000000"

android:startColor="#55000000" />

代码中 表示进度条方向为竖直向上。 　　布局中引用即可

android:id="@+id/load_pb"

style="?android:attr/progressBarStyleHorizontal"

android:layout_width="109dp"

android:layout_height="80dp"

android:layout_centerInParent="true"

android:background="@drawable/bkg_pic_clicktoload"

android:max="100"

android:progress="0"

android:progressDrawable="@drawable/loading_pb_drawable" />

2.建立如下一个drawable或者anim文件

android:fromDegrees="0"

android:pivotX="50%"

android:pivotY="50%"

android:toDegrees="360" >

android:innerRadiusRatio="3"

android:shape="ring"

android:thicknessRatio="8"

android:useLevel="false" >

android:centerColor="#043233"

android:centerY="0.5"

android:endColor="#000000"

android:startColor="#ffffff"

android:type="sweep"

android:useLevel="false" />
