标题HorizontalGridView设置setFocusScrollStrategy(HorizontalGridView.FOCUS_SCROLL_ITEM);后滚动会引发崩溃,不知是什么造成的?
提示
Device supports x86 but APK only supports armeabi-v7a
然后我了 armeabi 架构的模拟器 也不行,然后 ndk 配置加了x86架构的,运行也不行

调试时发现:
View positionView = horizontalGridView.getChildAt(Constants.TAG_FEATURE_POSITION);获取到的positionView 为null;
不知道为什么会为null,有点奇怪,不知道作者有发现没有。
我是这么处理的,可以解决问题
//延时一会儿,否则positionView获取为null
postDelayed(new Runnable() {
@Override
public void run() {
horizontalGridView.setSelectedPositionSmooth(Constants.TAG_FEATURE_POSITION);
View positionView = horizontalGridView.getChildAt(Constants.TAG_FEATURE_POSITION);
if (positionView != null) {
activity.mOldTitle = positionView.findViewById(R.id.tv_main_title);
positionView.requestFocus();
}
}
}, 0);
焦点一直往右或者往左移动,第一页和最后一页是抖动效果,中间页焦点移动到屏幕最右边怎么往下移动,移动到屏幕最左边是往上移动
