Simple Imageview Color Animation

Hi I am relatively new to Android, and I would like, if possible, some guidelines or suggestions on where to search in order to solve my issue. Apparently, I do not possess the rep

Solution 1:

How about having 2 images of the bottle? One (on foreground) would be an empty bottle with transparency The (on background) second one would be the "shape of the liquid"

when your activity starts, get the background one and animate it like posted on this topic : https://stackoverflow.com/a/12127985/4232337

Hope this helps!

Solution 2:

You can do this by using a custom ProgressBar. Even more simpler

<ProgressBarandroid:id="@+id/progressbar"style="?android:attr/progressBarStyleHorizontal"android:layout_width="60dp"android:layout_height="60dp"android:layout_marginBottom="2dp"android:layout_marginTop="2dp"android:indeterminateOnly="false"android:max="100"android:progress="30"android:progressDrawable="@drawable/progress_bar_clip" ></ProgressBar>

progress_bar_clip.xml

<?xml version="1.0" encoding="utf-8"?><layer-listxmlns:android="http://schemas.android.com/apk/res/android" ><itemandroid:id="@android:id/background"><clipandroid:clipOrientation="vertical"android:drawable="@drawable/ic_launcher"android:gravity="bottom" /></item><itemandroid:id="@android:id/progress"><clipandroid:clipOrientation="vertical"android:gravity="bottom" ><bitmapandroid:src="@drawable/ic_launcher" ></bitmap></clip></item></layer-list>

You don't have do load any animations. Just use a handler and increment the progress bar by 1.

finalProgressBarbar= (ProgressBar) findViewById(R.id.progressbar);

        finalHandlerhandler=newHandler();
        runnable = newRunnable() {

            @Overridepublicvoidrun() {
                if(bar.getProgress() != 100) {
                    bar.incrementProgressBy(1);
                    handler.postDelayed(runnable, 500);
                }
            }
        };;

        handler.post(runnable);
