android-view

问题 I currently have a working Android program that programmatically adds views to a LinearLayout. I would like those views to be animated in and cannot find any good resources on figuring out how to do this. Could someone point me in the right direction? 回答1: It's a very old question, but still interesting: you can use the attribute android:animateLayoutChanges="true" For example: <LinearLayout android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="wrap

问题 I want to test my Custom component UI rendering performance. I used the following test case to check the rendering performance. private long getLayoutTime(int layoutRes) { final Context targetContext = getInstrumentation().getTargetContext(); final LayoutInflater layoutInflater = LayoutInflater.from(targetContext); final long startTime = System.currentTimeMillis(); for (int i = 0; i < 1000; i++) { final View view = layoutInflater.inflate(layoutRes, null); view.setLayoutParams(new ViewGroup
