我正在尝试使用自定义抽屉图标实现一个简单的导航抽屉。
我做了什么 -
使用Android工作室创建NavDrawer项目。
在Stackoverflow上搜索类似的probs。我已经获得了onPostCreate()方法的参考资料,但我已经处理过了。
使用Android示例应用运行该项目。
查看图片 - 请参见左上角。我希望用我的图标

import android.widget.ListView;
import java.util.List;
public class MainActivity extends ActionBarActivity {
private ListView listView;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle actionBarDrawerToggle;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.left_drawer);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.ic_drawer,
R.string.open_drawer, R.string.close_drawer) {
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
// getActionBar().setTitle();
supportInvalidateOptionsMenu();
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getSupportActionBar().setTitle("Wealth Tracker");
supportInvalidateOptionsMenu();
}
};
drawerLayout.setDrawerListener(actionBarDrawerToggle);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
@Override

super.onPostCreate(savedInstanceState);
actionBarDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
// If the nav drawer is open, hide action items related to the content view
boolean drawerOpen = drawerLayout.isDrawerOpen(listView);
// menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
if(actionBarDrawerToggle.onOptionsItemSelected(item)){ return true; }
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

:
//if you use support action bar it is
ActionBar actionBar=getSupportActionBar();
actionBar.setHomeAsUpIndicator(R.drawable.newIcon);
//if you are not using support action bar it is
ActionBar actionBar=getActionBar();
actionBar.setHomeAsUpIndicator(R.drawable.newIcon);

这解决了我的问题(因为我有一个BaseActivity,并在MainActivity中声明了以下内容,它扩展了BaseActivity)。在 onCreate(Bundle savedInstanceState)方法内设置应用程序图标,如下所示:
android.support.v7.app.ActionBar actionBar = getSupportActionBar();
actionBar.setHomeAsUpIndicator(R.drawable.ic_drawer);
