獲取onDrawerOpened和onDrawerClosed回調

Question

我ActionBarDrawerToggle初始化

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

Answer 1

要獲得onDrawerOpened，onDrawerClosed和其他實用的方法來工作，你必須在你的活動來實現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) { 

    } 
} 

然後你必須加入這行來註冊監聽器和接收回調：

actionBarDrawerToggle.addDrawerListener(this);
