导航抽屉与edittext不工作

我在我的应用程序中使用导航抽屉。在listview之上，我使用edittext来创建一个搜索栏，它将搜索listview。但现在，当我单击列表项时，我的应用程序组关闭，而不是打开其他活动。怎么了？导航抽屉与edittext不工作

这里是堆栈跟踪：

的Java

public class MainActivity extends FragmentActivity { 
final String[] data ={"Aluminium","Gold","Zinc"}; 

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

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data); 

    final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout); 
    final ListView navList = (ListView) findViewById(R.id.left_drawer); 
    navList.setAdapter(adapter); 
    navList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, final int pos,long id){ 

      switch (pos){ 
       case 0: 
        Intent i = new Intent(MainActivity.this,Aluminium.class); 
        startActivity(i); 
        drawer.closeDrawer(navList); 
        break; 
       case 1: 
        Intent i2 = new Intent(MainActivity.this,Gold.class); 
        startActivity(i2); 
        drawer.closeDrawer(navList); 
        break; 
       case 2: 
        Intent i3 = new Intent(MainActivity.this,Zinc.class); 
        startActivity(i3); 
        drawer.closeDrawer(navList); 
        break; 
      } 
     } 
    }); 
    } 
}

你想在你抽屉里的EditText？ – Raghunandan

@Raghunandan是，可以添加搜索功能！ –

您可以在操作栏本身有一个搜索视图 – Raghunandan

这里LinearLayout是抽屉查看不是ListView。你必须通过的LinearLayout到closeDrawer()实例...

final LinearLayout linearLayout = (LinearLayout)findViewById(R.id.left_drawer_layout); 
    navList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, final int pos,long id){ 

      switch (pos){ 
       case 0: 
        Intent i = new Intent(MainActivity.this,Aluminium.class); 
        startActivity(i); 
        break; 
       case 1: 
        Intent i2 = new Intent(MainActivity.this,Gold.class); 
        startActivity(i2); 
        break; 
       case 2: 
        Intent i3 = new Intent(MainActivity.this,Zinc.class); 
        startActivity(i3); 
        break; 
      } 
      drawer.closeDrawer(linearLayout); 
     } 
    });

变化：

drawer.closeDrawer(navList);

到：

drawer.closeDrawer(Gravity.START);

你ListView（navList）ID为left_drawer没有ID为left_drawer_layout抽屉LinearLayout。

因此，无论是通过此linearlayout的对象，或者你也可以像上述方向关闭抽屉。
