使用AppCompat

使用AppCompat-v7在actionbar /工具栏中显示图标21(show icon in actionbar/toolbar with AppCompat-v7 21)

我试过这些 - 但仍然看不到像以前的图标：

getSupportActionBar().setLogo(R.drawable.ic_launcher); getSupportActionBar().setDisplayUseLogoEnabled(true); getSupportActionBar().setIcon(R.drawable.ic_launcher);

当我使用自定义工具栏时，它似乎工作 - 但这将迫使我触摸所有布局 - 有更好的方法吗？

I tried these - but still do not see the icon like before:

getSupportActionBar().setLogo(R.drawable.ic_launcher); getSupportActionBar().setDisplayUseLogoEnabled(true); getSupportActionBar().setIcon(R.drawable.ic_launcher);

It seems to work when I use custom toolbar - but that would force me to touch all layouts - is there a better way to do so?

最满意答案

getSupportActionBar().setDisplayShowHomeEnabled(true);

随着

getSupportActionBar().setIcon(R.drawable.ic_launcher);

getSupportActionBar().setDisplayShowHomeEnabled(true);

along with

getSupportActionBar().setIcon(R.drawable.ic_launcher);
