推荐答案

您需要做一些事情:

1. 通过设置透明颜色来禁用布局褪色:

1. Disable the layout fading by setting a transparent color:

drawer.setScrimColor(Color.TRANSPARENT);

锁上抽屉

Lock the drawer

drawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);

创建一个自定义抽屉类，该类允许在锁定模式下单击:

Create a custom drawer class which allows clicking through when in locked mode:

public class CustomDrawer extends DrawerLayout {

    public CustomDrawer(Context context) {
        super(context);
    }

    public CustomDrawer(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomDrawer(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        View drawer = getChildAt(1);

        if (getDrawerLockMode(drawer) == LOCK_MODE_LOCKED_OPEN && ev.getRawX() > drawer.getWidth()) {
            return false;
        } else {
            return super.onInterceptTouchEvent(ev);
        }
    }

}

在xml中使用此类:

Use this class in xml:

<com.example.myapplication.CustomDrawer
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <!-- The main content view -->
    </FrameLayout>
    <ListView android:layout_width="100dp"
              android:layout_height="match_parent"
              android:layout_gravity="start"
              android:background="#111"/>
</com.example.myapplication.CustomDrawer>
