更改图标导航抽屉 [英] Change Icon Of Navigation Drawer

问题描述

我有改变我的抽屉式导航栏图标，一个自定义的麻烦。目前我已经不得不实施其顶部有3条水平线的标准抽屉里的图标，但现在我要与我的自定义抽屉图标代替。

这是我的 mDrawerToggle 是目前：

  mDrawerToggle =新ActionBarDrawerToggle（这一点，
    mDrawerLayout，
    R.drawable.app_icon，
    R.string.drawer_open）{
        //我的code
    };
 

解决方案

下面是摘自样本code 创建导航抽屉

Activity.class

 公共类MainActivity延伸活动{
    私人DrawerLayout mDrawerLayout;
    私人ActionBarDrawerToggle mDrawerToggle;
    ...

    公共无效的onCreate（包savedInstanceState）{
        ...

        mDrawerLayout =（DrawerLayout）findViewById（R.id.drawer_layout）;
        mDrawerToggle =新ActionBarDrawerToggle（
                此时，/ *主机活动* /
                mDrawerLayout，/ * DrawerLayout对象* /
                R.drawable.ic_drawer，/ *导航抽屉图标来取代上插入符* /
                R.string.drawer_open，/ *开放抽屉的描述* /
                R.string.drawer_close / *关闭抽屉里的描述* /
                ）{

            / **调用时抽屉处于完全封闭的状态下稳定运行。 * /
            公共无效onDrawerClosed（查看视图）{
                super.onDrawerClosed（视图）;
                。getActionBar（）的setTitle（mTitle）;
            }

            / **调用时的抽屉里一个完全开放的状态下稳定运行。 * /
            公共无效onDrawerOpened（查看drawerView）{
                super.onDrawerOpened（drawerView）;
                。getActionBar（）的setTitle（mDrawerTitle）;
            }
        };

        //设置抽屉切换为DrawerListener
        mDrawerLayout.setDrawerListener（mDrawerToggle）;

        getActionBar（）setDisplayHomeAsUpEnabled（真）。
        getActionBar（）setHomeButtonEnabled（真）。
    }

    @覆盖
    保护无效onPostCreate（包savedInstanceState）{
        super.onPostCreate（savedInstanceState）;
        //同步发生onRestoreInstanceState后切换状态。
        mDrawerToggle.syncState（）;
    }

    @覆盖
    公共无效onConfigurationChanged（配置NEWCONFIG）{
        super.onConfigurationChanged（NEWCONFIG）;
        mDrawerToggle.onConfigurationChanged（NEWCONFIG）;
    }

    @覆盖
    公共布尔onOptionsItemSelected（菜单项项）{
        //通过事件ActionBarDrawerToggle，如果它返回
        //真，那么它处理的应用程序图标触摸事件
        如果（mDrawerToggle.onOptionsItemSelected（项目））{
          返回true;
        }
        //处理您的其他动作条上的项目...

        返回super.onOptionsItemSelected（项目）;
    }

    ...
}
 

I am having trouble with changing my navigation drawer icon to a custom one. I've currently had to implement the standard drawer icon which has 3 horizontal lines on top, but now I want to replace this with my custom drawer icon.

This is how my mDrawerToggle is at the moment:

mDrawerToggle=new ActionBarDrawerToggle(this,
    mDrawerLayout,
    R.drawable.app_icon,
    R.string.drawer_open) {
        // My code
    };

解决方案

Here is the sample code taken from Creating a Navigation Drawer

Activity.class

public class MainActivity extends Activity {
    private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mDrawerToggle;
    ...

    public void onCreate(Bundle savedInstanceState) {
        ...

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                mDrawerLayout,         /* DrawerLayout object */
                R.drawable.ic_drawer,  /* nav drawer icon to replace 'Up' caret */
                R.string.drawer_open,  /* "open drawer" description */
                R.string.drawer_close  /* "close drawer" description */
                ) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                super.onDrawerClosed(view);
                getActionBar().setTitle(mTitle);
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                getActionBar().setTitle(mDrawerTitle);
            }
        };

        // Set the drawer toggle as the DrawerListener
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);
    }

    @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);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Pass the event to ActionBarDrawerToggle, if it returns
        // true, then it has handled the app icon touch event
        if (mDrawerToggle.onOptionsItemSelected(item)) {
          return true;
        }
        // Handle your other action bar items...

        return super.onOptionsItemSelected(item);
    }

    ...
}
