【问题描述】：
我最近创建了一个名为 Hoops 的应用程序，并且我已经开发了很长时间。但是，我似乎遇到的主要问题是导航抽屉的滑动边距不在屏幕上，其他用户发现使用导航抽屉的滑动功能非常困难。菜单按钮工作得很好。我在网上查看了其他教程，它们似乎都显示了与我链接的论坛中相同的答案：Set drag margin for Android Navigation Drawer 但是，我已经尝试过这个解决方案，它似乎对我不起作用。如果有人有任何想法为什么它不工作，请你帮帮我。下面是 Main Activity 的代码，带有下面的导航抽屉：
package com.jehan.sportstutorials;
import android.content.Intent;

import android.support.design.widget.NavigationView;

import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
DrawerLayout drawerLayout;
Toolbar toolbar;
ActionBar actionBar;
TextView textView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
actionBar = getSupportActionBar();
actionBar.setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
actionBar.setDisplayHomeAsUpEnabled(true);
drawerLayout = (DrawerLayout) findViewById(R.id.navigation_drawer_layout);
NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
if (navigationView != null) {
setupNavigationDrawerContent(navigationView);
}
setupNavigationDrawerContent(navigationView);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
drawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
private void setupNavigationDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
textView = (TextView) findViewById(R.id.textView);
switch (menuItem.getItemId()) {
case R.id.item_navigation_drawer_basketball:
menuItem.setChecked(true);
textView.setText(menuItem.getTitle());
drawerLayout.closeDrawer(GravityCompat.START);
Intent i = new Intent(MainActivity.this, BasketballTutorial.class);
startActivity(i);
return true;
case R.id.item_navigation_drawer_help:
menuItem.setChecked(true);
textView.setText(menuItem.getTitle());
drawerLayout.closeDrawer(GravityCompat.START);
Intent intent2 = new Intent(MainActivity.this, HelpScreen.class);
startActivity(intent2);
return true;
}
return true;
}
});
}
}

如果有人想要导航抽屉滑动功能不起作用的实时示例，您可以在应用商店中测试我的应用。这是链接：https://play.google.com/store/apps/details?id=com.jehan.sportstutorials
总结：有谁知道如何增加导航抽屉的拖动边距，但不遵循我第一段链接中所述的传统方法？帮助将不胜感激。
