更改导航抽屉的图标

Question

我将导航抽屉图标更改为自定义图标时遇到问题.我目前不得不实现标准的抽屉图标,顶部有3条水平线,但现在我想用我的自定义抽屉图标替换它.

这就是我mDrawerToggle现在的样子:

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

Answer 1

使用下面的代码,它适用于V7 ActionBarDrawerToggle

mDrawerToggle.setDrawerIndicatorEnabled(false);

mDrawerToggle.setHomeAsUpIndicator(R.drawable.your_custom_icon);
 mDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
@Override
 public void onClick(View v) {
     if (mDrawerLayout.isDrawerVisible(GravityCompat.START)) {
          mDrawerLayout.closeDrawer(GravityCompat.START);
     } else {
         mDrawerLayout.openDrawer(GravityCompat.START);
    }
}
});

以下是从创建导航抽屉中获取的示例代码

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);
    }

    ...
}

Answer 3

这是主要活动

final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);


        toggle.setDrawerIndicatorEnabled(false);

        toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                drawer.openDrawer(GravityCompat.START);
            }
        });

        toggle.setHomeAsUpIndicator(R.drawable.menuicon);
