android之进度条

三种进度条方式：滚动进度条，水平进度条，自定义进度条

废话不多说，直接上代码。

xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:android="http://schemas.android.com/apk/res/android" >

    <!--滚动等待-->
    <Button
        android:id="@+id/bu_circle_progress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="滚动等待进度条"/>

    <!--水平进度条加载-->
    <Button
        android:id="@+id/bu_horizontal_progress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="水平进度条"/>

    <!--自定义加载提示框-->
    <Button
        android:id="@+id/bu_my_progress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="自定义提示框"/>
</LinearLayout>

　　java:

public class ProgressDemoActivity extends AppCompatActivity implements
        View.OnClickListener
{
   //滚动等待
    Button circle_progress;
    //水平进度条
    Button horizontal_progress;
    //自定义加载框
    Button my_progress;

  
    @Override

public void onClick(View v) {
