获取onDrawerOpened和onDrawerClosed回调

Question

我的ActionBarDrawerToggle初始化

actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.drawer_opened, R.string.drawer_closed);

Answer 1

要使用onDrawerOpened，onDrawerClosed和其他实用工具方法，你必须在你的活动中实现DrawerListener;

public class MyActivity extends AppCompatActivity implements DrawerListener {

    @Override
    public void onDrawerOpened(View arg0) {

    }

    @Override
    public void onDrawerClosed(View arg0) {

    }

    @Override
    public void onDrawerSlide(View arg0, float arg1) {

    }

    @Override
    public void onDrawerStateChanged(int arg0) {

    }
}

然后你必须添加这一行来注册监听器并接收回调：

actionBarDrawerToggle.addDrawerListener(this);
