在Android中循环移动时钟和逆时针

Question

我正在开发一个Android应用程序,其中我有两个同心圆,文本位于中心.我用过两个圆圈的drawable.我想将两个圆圈逆时针旋转,即一个顺时针旋转,另一个顺时针旋转.

我的代码在下面给出了活动代码中的动画文件夹和快照以供解释.

progress_left.xml

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:toDegrees="360" />

progress_right.xml

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="360"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:toDegrees="0" />

我的活动布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@color/red_theme"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btnStart"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:layout_marginLeft="28dp"
        android:text="Start" />

    <Button
        android:id="@+id/btnStop"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_marginRight="67dp"
        android:text="Stop" />


    <RelativeLayout
            android:id="@+id/main_imageLeft"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:background="@drawable/halfcircle"
            android:orientation="horizontal"
            android:padding="5dp" >

            <ImageView
                android:id="@+id/main_imageRight"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/halfcircle" />

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true"
                android:text="MUry"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#fff" />
        </RelativeLayout>
    <TextView
        android:id="@+id/textViewTime"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@color/Beige"
        android:layout_above="@+id/btnStop"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="30dp"
        android:textSize="100sp" />

</RelativeLayout>

我的活动代码

Animation animRight = AnimationUtils.loadAnimation(this,
                    R.anim.progress_right);
            animRight.setDuration(1000);
            mImageRight.startAnimation(animRight);

            Animation animLeft = AnimationUtils.loadAnimation(this,
                    R.anim.progress_left);
            animLeft.setDuration(1000);
            mLLLeft.startAnimation(animLeft);

只需使用"图像"视图更改相对布局,然后检查以下更新的代码:

        private ImageView mImageLeft, mImageRight, mImageProfile;
        private ImageView mLLLeft;
        mLLLeft = (ImageView) findViewById(R.id.main_imageLeft1);
        mImageRight = (ImageView) findViewById(R.id.main_imageRight);

        Animation animRight = AnimationUtils.loadAnimation(this,
        R.anim.progress_right);
        animRight.setDuration(1000);
        mImageRight.startAnimation(animRight);
        Animation animLeft = AnimationUtils.loadAnimation(this,R.anim.progress_left);
        animLeft.setDuration(1000);
        mLLLeft.startAnimation(animLeft);
