【问题描述】：

如何在其他Activity中使用android默认Navigation？

我不想使用返回按钮。

主活动：

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener 

TextView tvhead,tv6,tv7,tv8,tv9,tvbottom;
Typeface schriftart_courier_prime;

@Override
protected void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);


    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.setDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    FragmentManager fm = getFragmentManager();
    fm.beginTransaction().replace(R.id.content_frame, new MainFragment()).commit();


@Override
public void onBackPressed() 
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    if (drawer.isDrawerOpen(GravityCompat.START)) 
        drawer.closeDrawer(GravityCompat.START);
     else 
        super.onBackPressed();
    


@Override
public boolean onCreateOptionsMenu(Menu menu) 
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;


@Override
public boolean onOptionsItemSelected(MenuItem item) 
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_about) 

        Intent getNameScreenIntent2 = new Intent (this, AboutActivity.class);


        final int result = 1;

        startActivity(getNameScreenIntent2);

        return true;

        //Actionbar element für später
    else if (id == R.id.action_phone)

    

    return super.onOptionsItemSelected(item);



@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) 

    FragmentManager fm = getFragmentManager();

    int id = item.getItemId();

    if (id == R.id.nav_home) 
        fm.beginTransaction().replace(R.id.content_frame, new MainFragment()).commit();
     else if (id == R.id.nav_experiments) 

        Intent getNameScreenIntent = new Intent(this, ExperimentsList.class);

        final int result = 1;

        startActivity(getNameScreenIntent);
     else if (id == R.id.nav_website) 

        Intent getNameScreenIntent = new Intent(this, Web.class);

        final int result = 1;

        startActivity(getNameScreenIntent);
     else if (id == R.id.nav_share) 

        Intent share = new Intent(Intent.ACTION_SEND);
        share.setType("text/plain");
        share.putExtra(Intent.EXTRA_TEXT, getString(R.string.share_text));
        startActivity(Intent.createChooser(share, getString(R.string.share_title)));
    

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;

【问题讨论】：

您能否通过将示例代码减少到演示问题所需的最低限度，或提供更多解释，或两者兼而有之，让人们更容易帮助您？

【参考方案1】：

让所有需要该抽屉的活动都继承自自定义抽象 Activity 类，该类将抽屉添加到其 onCreate 方法中。

创建一个类似的类：

public abstract class MyNavigationActivity extends AppCompatActivity  
   @Override 
   protected void onCreate(Bundle savedInstanceState)  
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
     setSupportActionBar(toolbar);
     DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
     ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
        this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
     drawer.setDrawerListener(toggle);
     toggle.syncState();

     NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
     navigationView.setNavigationItemSelectedListener(this);
    
 

然后：

public class MyActivity extends MyNavigationActivity 
   @Override 
   protected void onCreate(Bundle savedInstanceState)  
       super.onCreate(savedInstanceState);
       FragmentManager fm = getFragmentManager();
       fm.beginTransaction().replace(R.id.content_frame, new MainFragment()).commit();

谢谢回答，但自定义摘要是什么意思？

请举个例子

你能用我的代码做这个例子吗？这更好理解：D 我是 Android 编程新手
