在imageview上添加低不透明度彩色覆盖

<ImageView
    android:id="@+id/myImageView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/my_image" />

ImageView myImageView = findViewById(R.id.myImageView);
Drawable drawable = myImageView.getDrawable();
Drawable colorOverlay = new ColorDrawable(Color.parseColor("#800000FF")); // 这里的颜色代码代表半透明的蓝色（R:128 G:0 B:255），可以根据需要修改
colorOverlay.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());

LayerDrawable layerDrawable = new LayerDrawable(new Drawable[] { drawable, colorOverlay });
myImageView.setImageDrawable(layerDrawable);
