Set drawable dynamically for AnalogClock widget

问题

How to do that?

I have AnalogClock on my xml. And I want drawable for the android:dial to change programatically.

I tried

remoteviews.setImageViewResource(R.id.AnalogClock, R.drawable.w0);

or

remoteviews.setInt(R.id.AnalogClock, "setDialResource", R.drawable.w0);

Both can not accomplish it. Anyone manage to do this?

回答1:

Finally make it works. I put transparent image on AnalogClock android:dial Then use FrameLayout to overlay ImageView and AnalogClock.

Then use

remoteviews.setInt(R.id.ImageView, "setBackgroundResource", R.drawable.w0);

to change the ImageView image. It is feasible solution at the moment.

回答2:

Normally remoteviews.setImageViewResource(R.id.AnalogClock, R.drawable.w0) should do the trick. Are you sure that the View refferenced by R.id.AnalogClock is of type ImageView
