not working for me
activity.findViewById(R.string.abc_action_bar_up_description).performClick();
I set in activity
setSupportActionBar(toolbar);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
...
}
});
To make a click on the navigation button which is located in the toolbar you need to do the following:
Add text to the navigation button
toolbar.setNavigationContentDescription("up");
After finding it in the following way
final ArrayList<View> outViews = Lists.newArrayList();
activity.findViewById(R.id.toolbar).findViewsWithText(outViews, "up", View.FIND_VIEWS_WITH_CONTENT_DESCRIPTION);
outViews.get(0).performClick();
您应该将您的东西称为R.id.yourStuff
&&检查是否为android:clickable="true"
(如果不是按钮)。
