You need to specify android:src="@..."
in your ImageViews if you want to display them in the design preview. 如果要在设计预览中显示它们,则需要在ImageViews中指定
android:src="@..."
。
If you only set the Image in your Activity class, like 如果您仅在活动类中设置图片,例如
((ImageView)findViewById(R.id.imageView1)).setImageDrawable(...);
they will not be displayed until the program is executed. 在程序执行之前,它们不会显示。
