App shows black image on Image View instead of actual image at runtime

Question

The ImageView fills with black color after setting an image.

I'm setting image with this line

  super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Root = findViewById(R.id.Iv);

    sensorManager = (SensorManager) getSystemService(Service.SENSOR_SERVICE);
    Proximity = sensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);

    //Root.setBackgroundColor(Color.MAGENTA);
   Root.setImageResource(R.drawable.a);
}

Please Help!

What the resolution of your image ? did you by any chance cover the ImageView by any other view — Mouaad Abdelghafour AITALI, Aug 23 '20 at 14:04

Please try with this

  Context mContext = this;
  Root.setImageDrawable(mContext.getResources().getDrawable(R.drawable.a));

As mobile screen comes with different sizes, so may be your image resolution is high or not compatible to the width & height of ImageView. Try to decrease the size of image so that it loads on Runtime also.
