【android】TabLayout文字閃爍問題

安卓MD設計提供了一個很是酷炫的效果，TabLayout拿來作選項卡時很是合適的，可是在實際使用中發現22.2.1版本號的TabLayout在ViewPager滑動的時候會出現閃爍現象。

解決方法：在gradle文件裏

1：要麼升級到23.x（compile 'com.android.support:design:23.1.1'）

2：要麼使用22.0裏最後一個沒有bug的版本（compile 'com.android.support:design:22.2.0'）

 

以上只是針對tabLayout文字閃爍的狀況，若是圖片閃爍要麼升級到23.x

要麼請參考如下方式自行解決，來源http://stackoverflow.com/questions/31828610/why-do-the-tablayouts-tabs-icons-texts-blink-when-swiping-between-pages

use the old version (22.2.0) as I've mentioned above.

you need to avoid using selectors for the icons. Use the exact image resource ids instead:

private static final int[] TAB_ICONS_UNSELECTED = {... };
private static final int[] TAB_ICONS_SELECTED = {... };

 

update the icons based on the page selections, as such:

mViewPager.addOnPageChangeListener(new OnPageChangeListener() {
@Override
public void onPageSelected(final int position) {
for (int i = 0; i < tabLayout.getTabCount(); ++i)
tabLayout.getTabAt(i).setIcon(i != position ? TAB_ICONS_UNSELECTED[i] : TAB_ICONS_SELECTED[i]);
}
});

 

Also, remember to call about the same loop when initializing the TabLayout. Something like that:

for (int i = 0; i < tabLayout.getTabCount(); ++i)
tabLayout.getTabAt(i).setIcon(i != mViewPager.getCurrentItem() ? TAB_ICONS_UNSELECTED[i] : TAB_ICONS_SELECTED[i]);

I think that this should also fix the issue for texts and not just icons.
