Question

我有活动，我们称之为TestActivity。此TestActivity扩展了具有导航抽屉的Activity。在TestActivity中，我想更改NavigationDrawerToggle并用向上箭头替换它。

public class Test extends DashboardActivity {

    private DrawerLayout navDrawerLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        navDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

        getActionBar().setDisplayHomeAsUpEnabled(true);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.test, menu);
        return true;
    }

    @Override
    public void onBackPressed() {
        this.finish();
        super.onBackPressed();
    }

}

仪表板活动有点长，我还有更多东西，但基本上它遵循本教程：http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/

我认为你想要的是一个Activity使用ActionBarDrawerToggle而另一个仍然使用DrawerLayout，但没有切换。在这种情况下，最简单的方法是拥有两个“基础”类。这是一个例子。

1）实现Activity 的DrawerLayout

public class BaseDrawerActivity extends Activity {

    protected DrawerLayout mDrawer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_drawer_layout);

        mDrawer = ...
    }

}

2）实施Activity 的ActionBarDrawerToggle

public class BaseDrawerToggleActivity extends BaseDrawerActivity {

    private ActionBarDrawerToggle mDrawerToggle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mDrawerToggle = ...
        mDrawer.setDrawerListener(mDrawerToggle);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (mDrawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        mDrawerToggle.syncState();
    }

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

}

如果您想使用DrawerLayout 而不是切换，子类BaseDrawerActivity以及何时想要使用{/ 1}} >切换，子类Activity。因此，您的BaseDrawerToggleActivity将如下所示：
