Android FrameLayout / ImageView旋转问题

Question

I am rotating a FrameLayout which contains an Imageview with image.When I add another Imageview on that rotated FrameLayout than the added imageview also get rotates by default as usual.

To prevent this as I need the added ImageView not to be rotated,I rotate that ImageView at the reverse angle from FrameLayout.

I am rotating FrameLayout using below code:

(1)Rotate:

    float angle = mainFrm.getRotation();
    if (angle == 0) {
        angle = 360;
    }
    angle = angle - 90;
    mainFrm.setRotation(angle);

(2)Flip Vertical

    float angle = mainFrm.getRotationX();
    if (angle == 0) {
        angle = 360;
    }
    angle = angle - 180;
    mainFrm.setRotationX(angle);

(3)Flip Horizontal

    float angle = mainFrm.getRotationY();
    if (angle == 0) {
        angle = 360;
    }
    angle = angle - 180;
    mainFrm.setRotationY(angle);

I am rotating ImageView using following code:

    if(mainFrm.getRotation()!=0)
    {
        iv.setRotation(-(mainFrm.getRotation()));
    }
    if(mainFrm.getRotationX()!=0)
    {
        iv.setRotationX(-(mainFrm.getRotationX()));
    }
    if(mainFrm.getRotationY()!=0)
    {
        iv.setRotationY(-(mainFrm.getRotationY()));
    }

Now the issue I am facing is when I first rotate frame(270 degree),then flip it vertically(180 degree) and after add an ImageView to that rotated frame it rotates the ImageView as well.

Here I am attaching images as well. This is the issue

I need solution like this

Any help/suggestions will be highly appreciated.

Thanks in advance

My Framelayout is like..

<FrameLayout android:id="@+id/frame"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:background="#33ffff">
    <ImageView android:id="@+id/image1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/ic_launcher"/>

    <ImageView android:id="@+id/image2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:src="@drawable/ic_launcher"/>
</FrameLayout>

and my java code is,

mFrame = (FrameLayout) findViewById(R.id.frame);
    mImage1 = (ImageView) findViewById(R.id.image1);
    mImage2 = (ImageView) findViewById(R.id.image2);
    float angle = mFrame.getRotation();
    if(angle == 0) {
        angle = 180;
    }
    mFrame.setRotation(angle);
    mImage2.setRotation(-angle);

Hope this will help you...
