java - 在类 android.support.design.widget.NavigationView 中获取错误

Question

我正在 android 中开发一个应用程序，我想在其中实现汉堡菜单。我正在使用 eclipse Mars.2 Release (4.5.2) 和使用 android.support.design.widget.NavigationView library.support design library 和 support appcompat library 在 mac os 中开发也有相同的版本和

我收到此错误消息:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.demohamb/com.example.demohamb.MainActivity}: android.view.InflateException: Binary XML file line #28: Error inflating class android.support.design.widget.NavigationView

请给我一些汉堡菜单的演示示例。

@MainActivity

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Initializing Toolbar and setting it as the actionbar
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    //Initializing NavigationView
    navigationView = (NavigationView) findViewById(R.id.navigation_view);

    //Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

        // This method will trigger on item Click of navigation menu
        @Override
        public boolean onNavigationItemSelected(MenuItem menuItem) {


            //Checking if the item is in checked state or not, if not make it in checked state
            if(menuItem.isChecked()) menuItem.setChecked(false);
            else menuItem.setChecked(true);

            //Closing drawer on item click
            drawerLayout.closeDrawers();

            //Check to see which item was being clicked and perform appropriate action
            switch (menuItem.getItemId()){


                //Replacing the main content with ContentFragment Which is our Inbox View;
                case R.id.inbox:
                    Toast.makeText(getApplicationContext(),"Inbox Selected",Toast.LENGTH_SHORT).show();
                    ContentFragment fragment = new ContentFragment();
                    android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
                    fragmentTransaction.replace(R.id.frame,fragment);
                    fragmentTransaction.commit();
                    return true;

                // For rest of the options we just show a toast on click

                case R.id.starred:

                    return true;

            }
        }
    });

    // Initializing Drawer Layout and ActionBarToggle
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
    ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.openDrawer, R.string.closeDrawer){

        @Override
        public void onDrawerClosed(View drawerView) {
            // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
            super.onDrawerClosed(drawerView);

        }
    };

    //Setting the actionbarToggle to drawer layout
    drawerLayout.setDrawerListener(actionBarDrawerToggle);

    //calling sync state is necessay or else your hamburger icon wont show up

Answer 1

当您的appcompat 库和设计支持库 的版本不匹配时，可能会出现此问题。

例子

编译 'com.android.support:appcompat-v7:23.1.1'//appcompat 库

compile 'com.android.support:design:23.1.1'//设计支持库

因此请检查您的 build.gradle 文件并尝试匹配这些文件。

希望对您有所帮助。
