我在布局中有一个TextView,背景是一个选择器.TextView的文本设置为从HTML跨越.然后我用LinkMovementMethod设置TextView.
现在,当我点击TextView时,click事件不会发送到其父布局以触发选择器.
该如何解决?
我有这个导航抽屉,工作得非常好.重构我的代码我删除了所有onOptionsItemSelecteds
活动,并使所有活动都继承自扩展AppComplatActivity
并实现所有必要方法的基本活动.在点击汉堡图标后,即使我有syncstate
()和所有东西,它也不再起作用.
任何线索为什么这不起作用?
其中一项活动:
public class MainActivity extends BaseActivity implements SearchFilterFragment.OnFragmentInteractionListener {
NavigationView navigationView;
DrawerLayout drawerLayout;
private Tracker mTracker;
@Override
protected void onResume() {
super.onResume();
drawerLayout.openDrawer(GravityCompat.START);
}
@Override
protected void onPostResume() {
super.onPostResume();
mTracker.setScreenName("MainActivity" + "-----");
mTracker.send(new HitBuilders.ScreenViewBuilder().build());
}

我一直在尝试使用新的设计库,但我有一个工具栏而不是不赞成使用的操作栏。问题在于工具栏占用了活动中的整个区域。我一直在尝试不同的示例,并用它们替换了布局文件,我尝试了不同的width和height值。我不知道为什么会这样。都没有用!是什么原因造成的?
非常感谢您的帮助。
