Constrain drawableLeft and drawableRight's height to TextView's height

问题

I have the following TextView:

<TextView
    android:drawableLeft="@drawable/loading"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Updating Rates" />

And the result is this:

How do I make the loading circle drawable constrain proportionally so its height matches the height of the text?

Also, if possible, I would like to add some spacing between the text and the image.

回答1:

To make the loading smaller just make the images smaller.

Or use RelativeLayout and put the loading in an ImageView and scale it.

Or you can add padding between the drawables and the text using android:drawablePadding (or setCompoundDrawablePadding()):

android:drawablePadding="3dp"

I think I found the solution, but a bit late

Drawable drawable = getResources().getDrawable(R.drawable.s_vit);
drawable.setBounds(0, 0, (int)(drawable.getIntrinsicWidth()*0.5),(int)(drawable.getIntrinsicHeight()*0.5));
ScaleDrawable sd = new ScaleDrawable(drawable, 0, scaleWidth, scaleHeight);
Button btn = findViewbyId(R.id.yourbtnID);
btn.setCompoundDrawables(sd.getDrawable(), null, null, null);

Ravi's solution worked for me, but on some devices drawable was disappearing. Fixed this by removing the scaling.

    int bound = (int) (drawable.getIntrinsicWidth() * 0.5);
    drawable.setBounds(0, 0, bound, bound);
    b.setCompoundDrawables(drawable, null, null, null);

A Better solution will to create a XML in drawable folder and add the image to this XML, and maintain scaleType as "fitXY". Now you can make this XML as the drawableLeft.

You just need to declare two separate views imageview and textview, and set them accordingly
