error: cannot find symbol class OnProgressChanged

[kleysonr]

What are you trying to achieve or the steps to reproduce?

I'm trying to use the Fotoapparat in a java project. I copied the res folders from the git sample as well as ActivityJava.java and PermissionsDelegate.java files.

After fixing all the imports, I'm getting "Cannot resolve symbol OnProgressChanged" in the following method.

    private void zoomSeekBar() {
        SeekBar seekBar = findViewById(R.id.zoomSeekBar);

        seekBar.setOnSeekBarChangeListener(new OnProgressChanged() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                fotoapparat.setZoom(progress / (float) seekBar.getMax());
            }
        });
    }

If a comment out the following code, I can run the app without any error:

        seekBar.setOnSeekBarChangeListener(new OnProgressChanged() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                fotoapparat.setZoom(progress / (float) seekBar.getMax());
            }
        });

Context:

• FA version: 2.7.0
• Devices/APIs affected: API-21

Well apparently you don't have a xml with zoomSeekBar id. This is not a library issue

Hi @Diolor ,

My project is basically a clone of the Fotoapparat's sample (https://github.com/RedApparat/Fotoapparat/tree/master/sample) but using the java version.

And there is the zoomSeekBar id in the activity_main.xml file (.xml below).

Might it be an issue in java sample instead ?

Just change zoomSeekBar method definition in ActivityJava:

private void zoomSeekBar() {
    SeekBar seekBar = findViewById(R.id.zoomSeekBar);

    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            fotoapparat.setZoom(progress / (float) seekBar.getMax());
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    });
}
