mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLayout.closeDrawers();

工作得很好。

DrawerLayout mDrawerLayout= (DrawerLayout) findViewById(R.id.drawer_layout)

closeDrawer(); // called when you want to close

public void closeDrawer() {
  if (mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
    mDrawerLayout.closeDrawer(GravityCompat.START);
  }
}

如果你有 mDrawerLayout 作为你的抽屉布局，你可以在它打开时关闭它。

@Override
public void onBackPressed() {
    if (this.mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
        this.mDrawerLayout.closeDrawer(GravityCompat.START);
    } else {
        super.onBackPressed();
    }
}

在开关盒结束的 onNavigationItemSelected 的右下角，您应该纠正它。mDrawerLayout.closeDrawers();

public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        switch (item.getItemId()){

        }
   mDrawerLayout.closeDrawers();
   return true;
}
