android之進度條

三種進度條方式：滾動進度條，水平進度條，自定義進度條

廢話不多說，直接上代碼。

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" >

    <!--滾動等待-->
    <Button
        android:id="@+id/bu_circle_progress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="滾動等待進度條"/>

    <!--水平進度條加載-->
    <Button
        android:id="@+id/bu_horizontal_progress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="水平進度條"/>

    <!--自定義加載提示框-->
    <Button
        android:id="@+id/bu_my_progress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="自定義提示框"/>
</LinearLayout>

　　java:

public class ProgressDemoActivity extends AppCompatActivity implements
        View.OnClickListener

   //滾動等待
    Button circle_progress;
    //水平進度條
    Button horizontal_progress;
    //自定義加載框
    Button my_progress;

　自定義的布局需要在layout中根據自己需求來設計
