英文:
App shows black image on Image View instead of actual image at runtime
问题
ImageView在设置图像后变成了黑色。
我使用以下代码来设置图像
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);
}
英文:
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!

由于移动屏幕具有不同的尺寸，因此您的图像分辨率可能较高，或者与 ImageView 的宽度和高度不兼容。尝试减小图像的尺寸，以便它可以在运行时加载。
英文:
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.
