本文实例为大家分享了Android ProgressBar实现进度条的具体代码,供大家参考,具体内容如下
1.XML布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:textSize="20sp"
android:layout_marginTop="30dp"
android:layout_centerHorizontal="true"
android:text="设置当前进度固定不可拖动"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<LinearLayout
android:id="@+id/full"
android:layout_centerInParent="true"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="60dp">
<TextView
android:id="@+id/progesss_value1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ddd"
android:gravity="center"
android:paddingBottom="8dp"
android:paddingLeft="4dp"
android:paddingRight="4dp"
android:paddingTop="2dp"
android:textColor="@android:color/white"
android:textSize="12sp"
android:text="20%" />
<ProgressBar
android:layout_gravity="center_horizontal"
android:id="@+id/progesss1"
style="@style/Widget.AppCompat.ProgressBar.Horizontal"
android:layout_width="330dp"
android:layout_height="wrap_content"
android:background="@drawable/myprogressbar"
android:indeterminateDrawable="@android:drawable/progress_indeterminate_horizontal"
android:indeterminateOnly="false"
android:max="100"
android:maxHeight="50dp"
android:minHeight="16dp"
android:progress="20"
android:progressDrawable="@drawable/myprogressbar" />
</LinearLayout>
</RelativeLayout>
2.myprogressbar布局
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
