Changing navigation drawer icon

Question

我有一个问题，我有不同的活动，具有不同的背景颜色（白色或蓝色），菜单图标也必须是白色或蓝色（与活动背景相反），我在更改活动后找不到正确的更改方式， 我怎样才能做到这一点？

Answer 1

U must do like this:

mDrawerToggle = new ActionBarDrawerToggle(
            this,                 
            mDrawerLayout,         
            R.drawable.ic_drawer, //<-- This is the icon provided by Google itself
            R.string.drawer_open,
            R.string.drawer_close 
            )

This in setUp() method.

And dont forget to add these code:

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);
}
