Cómo configurar onclick listener para un botón en un fragmento en android

Mi aplicación contiene un formulario como se muestra en la siguiente imagen:

• Android: onClick responde sólo al segundo clic en listview
• Droid: ¿Cómo obtener la identificación del botón del método onClick descrito en XML?
• ¿Cómo exactamente el atributo android: onClick XML difiere de setOnClickListener?
• Realizar el botón Acción en Haga clic en Notificación personalizada: Android
• Android principiante: toque eventos en android gridview

Cuando hago clic en el botón de opciones del menú, el cajón se abre como se muestra en la siguiente imagen:

Quiero que el cajón se abra cuando se presiona la posición de selección del botón.

Mis códigos son

RegisterBlood.java

... public class RegisterBlood extends Activity implements OnItemClickListener { DrawerLayout dLayout, dLayout2; ListView dList, dList2; ArrayAdapter<String> adapter, adapter2; String[] state_data2; String city = "", state = ""; Button location; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.selectlocation); Bundle args = new Bundle(); Fragment detail = new RegisterBloodFragment(); detail.setArguments(args); FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction().replace(R.id.content_frame, detail) .commit(); ... dLayout = (DrawerLayout) findViewById(R.id.drawer_layout); dList = (ListView) findViewById(R.id.left_drawer); adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, state_data); dList.setAdapter(adapter); dList.setSelector(android.R.color.holo_blue_dark); // dLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED); dList.setOnItemClickListener(this); } @Override public boolean onKeyDown(int keyCode, KeyEvent e) { if (keyCode == KeyEvent.KEYCODE_MENU) { // your action... if (!dLayout.isDrawerOpen(dList)) { dLayout = (DrawerLayout) findViewById(R.id.drawer_layout); dList = (ListView) findViewById(R.id.left_drawer); adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, state_data2); dList.setAdapter(adapter); dLayout.openDrawer(dList); dList.setOnItemClickListener(this); } return true; } if (keyCode == KeyEvent.KEYCODE_BACK) { // your action... if (dLayout.isDrawerOpen(dList)) { dLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED); } return true; } return super.onKeyDown(keyCode, e); } @Override public void onItemClick(AdapterView<?> arg0, View v, final int position, long id) { // TODO Auto-generated method stub ... dLayout2 = (DrawerLayout) findViewById(R.id.drawer_layout); dList2 = (ListView) findViewById(R.id.left_drawer); adapter2 = new ArrayAdapter<String>(RegisterBlood.this, android.R.layout.simple_list_item_1, city_data); dList2.setAdapter(adapter2); dList2.setSelector(android.R.color.holo_blue_dark); dLayout2.openDrawer(dList2); dLayout2.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN); dList2.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View v, int position2, long id) { dLayout2.closeDrawers(); state = state_data2[position]; city = city_data[position2]; Bundle args = new Bundle(); args.putString("Menu", city_data[position2] + " (" + state_data2[position] + ")"); Fragment detail = new RegisterBloodFragment(); detail.setArguments(args); FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction() .replace(R.id.content_frame, detail).commit(); } }); }} 

RegisterBloodFragment.java

 ... public class RegisterBloodFragment extends Fragment implements OnClickListener { Button location; @Override public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle args) { View view = inflater.inflate(R.layout.registerblood, container, false); String menu = getArguments().getString("Menu"); location= (Button) view.findViewById(R.id.etlocation); location.setText(menu); //Context c=getActivity(); //location.setOnClickListener(c.getApplicationContext().set); return view; } @Override public void onClick(View v) { // TODO Auto-generated method stub Toast.makeText(getActivity(), "Yes", Toast.LENGTH_SHORT).show(); } } 

Registerblood.xml

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/silver" android:gravity="center" android:orientation="vertical" android:paddingBottom="10dp" android:paddingLeft="40dp" android:paddingRight="40dp" android:paddingTop="10dp" > <EditText android:id="@+id/bregetName" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="18dp" android:ems="10" android:hint="Name" /> <EditText android:id="@+id/bregetBloodGroup" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="18dp" android:ems="10" android:hint="Blood Group" /> <Button android:id="@+id/etlocation" style="@android:style/Widget.EditText" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="14dp" android:ems="10" android:hint="select location" > </Button> <Button android:id="@+id/bregbtnSignUp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginBottom="10sp" android:layout_marginTop="10sp" android:background="@drawable/button" android:shadowColor="#A8A8A8" android:shadowDx="0" android:shadowDy="0" android:shadowRadius="5" android:text="Submit" android:textColor="#FFFFFF" android:textSize="24sp" /> </LinearLayout> 

Selectlocation.xml

 <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent"> <FrameLayout android:id="@+id/content_frame" android:layout_width="match_parent" android:layout_height="match_parent" > </FrameLayout> <ListView android:id="@+id/left_drawer" android:layout_width="240dp" android:layout_height="match_parent" android:layout_gravity="end" android:choiceMode="singleChoice" android:divider="@android:color/transparent" android:dividerHeight="0dp" android:background="#fff"/> 

Mi pregunta es:

¿Cómo agregar el onclicklistener para seleccionar la ubicación en RegisterBlood.java o llamar onClickListener que está en RegisterBlood.java de RegisterBloodFragment.java ?

Por favor, ayúdame.

 @Override public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle args) { View view = inflater.inflate(R.layout.registerblood, container, false); String menu = getArguments().getString("Menu"); location = (Button) view.findViewById(R.id.etlocation); location.setText(menu); location.setOnClickListener(this); return view; } @Override public void onClick(View v) { RegisterBlood activity = (RegisterBlood) getActivity(); // Now you can contact your activity through activity eg: activity.onKeyDown(KeyEvent.KEYCODE_MENU, null); } 

 public class YourClassName extends Fragment implements View.OnClickListener public Button button; 

 @Override public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle args) { button = (Button) inflater.inflate(R.layout.registerblood, container, false).findViewById(R.id.your_button_id); button.setOnClickListener(this); } 

 @Override public void onClick(View v) { //YOUR CODE HERE } 

 your_edittext.setOnFocusChangeListener(new OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { if (hasFocus) { Toast.makeText(getApplicationContext(), "got the focus", Toast.LENGTH_LONG).show(); // OPEN THE DRAWER HERE } else { Toast.makeText(getApplicationContext(), "lost the focus", Toast.LENGTH_LONG).show(); } }
