我正在尝试将操作栏的主页更改为向上指示符。现在它显示一个箭头(打开时)和3个条纹(关闭时):
我想用自定义drawable替换此箭头。以下代码不起作用:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setLogo(getResources().getDrawable(R.drawable.actionbar_logo));
getSupportActionBar().setDisplayUseLogoEnabled(true);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.string.app_name, /* "open drawer" description for accessibility */
R.string.app_name /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
//getActionBar().setTitle(mTitle);
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
//getActionBar().setTitle(mDrawerTitle);
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerToggle.setHomeAsUpIndicator(getResources().getDrawable(R.drawable.actionbar_logo));
mDrawerLayout.setDrawerListener(mDrawerToggle);
如果我在样式中使用<item name="displayOptions">useLogo|showHome|showTitle</item>
,它会显示除原始homeAsUpIndicator
之外的自定义drawable,而我想要的是替换它
我怎样才能做到这一点?谢谢!
