Qual è il modo corretto di usare Toolbar e SwipeRefreshLayout?

Question

Sto tentando di utilizzare SwipeRefreshLayout e una barra degli strumenti, ma ogni volta che utilizzo sia il Cerchio di progresso appare sulla barra degli strumenti che è davvero pessimo in termini di design. Ho provato a mettere SwipeRefreshLayout sotto la barra degli strumenti, ma questo non funziona, il cerchio del progresso appare ancora sopra di esso (sopra la barra di stato). Mi piacerebbe utilizzare la barra degli strumenti e il layout contemporaneamente come nell'app Gmail. Sto usando la libreria AppCompat.

Ecco il mio codice:

<?xml version="1.0" encoding="utf-8"?> 


    <android.support.v4.widget.SwipeRefreshLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/swipe_container" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 




    <ScrollView 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 


     <RelativeLayout 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"> 

      <include layout="@layout/bluetooth_toolbar" 
       android:id="@+id/bluetooth_toolbar"/> 


      <TextView 
       android:id="@+id/swipeTo" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:text="Swipe down to refresh" 
       android:textSize="20sp" 
       android:layout_below="@+id/bluetooth_toolbar" 
       android:layout_centerHorizontal="true" /> 

      <ListView 
       android:id="@+id/newDevices" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:layout_below="@id/swipeTo" 
       android:layout_marginTop="50dp" /> 

      <ListView 
       android:id="@+id/pairedDevices" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:layout_below="@id/newDevices" 
       android:layout_marginTop="50dp" /> 
     </RelativeLayout> 
    </ScrollView> 

    </android.support.v4.widget.SwipeRefreshLayout>

public class BluetoothActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener { 


private static final int REQUEST_ENABLE_BT = 0; 
private BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); 
private SwipeRefreshLayout mSwipeRefreshLayout; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_bluetooth); 
    Toolbar bluetoothToolbar = (Toolbar) findViewById(R.id.bluetooth_toolbar); 
    setSupportActionBar(bluetoothToolbar); 
    final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha); 
    upArrow.setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.SRC_ATOP); 
    getSupportActionBar().setHomeAsUpIndicator(upArrow); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_container); 
    mSwipeRefreshLayout.setOnRefreshListener(this); 
    mSwipeRefreshLayout.setColorScheme(
      R.color.yellow, 
      R.color.flashy_blue, 
      R.color.yellow, 
      R.color.flashy_blue); 


    if (bluetoothAdapter == null) { 
     // Device does not support Bluetooth 
    } 
    if (!bluetoothAdapter.isEnabled()) { 
     Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); 
     startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT); 
    } 


} 


public void onRefresh() { 
    Toast.makeText(this, getString(R.string.bluetooth_refresh), Toast.LENGTH_SHORT).show(); 
    new Handler().postDelayed(new Runnable() { 
     @Override 
     public void run() { 
      mSwipeRefreshLayout.setRefreshing(false); 
     } 
    }, 2000); 

    bluetoothAdapter.startDiscovery(); 

if (bluetoothAdapter.getScanMode() != BluetoothAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE) { 
    Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); 
     discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300); 
    startActivity(discoverableIntent); 
     } 


} 


protected void onDestroy() { 
    super.onDestroy(); 
    bluetoothAdapter.cancelDiscovery(); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.bluetooth, 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(); 
    if (id == R.id.action_settings) { 
     startActivityForResult(new Intent(Settings.ACTION_BLUETOOTH_SETTINGS), 0); 
     return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 

}

Grazie

questo è perché la toolbar è parte del layout relativa che ottiene rinfrescato. è necessario escludere la barra degli strumenti in questo modo:

<?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:orientation="vertical"> 

    <include layout="@layout/bluetooth_toolbar" 
     android:id="@+id/bluetooth_toolbar"/> 

    <android.support.v4.widget.SwipeRefreshLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/swipe_container" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 

    <ScrollView 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 

     <RelativeLayout 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"> 

     <TextView 
      android:id="@+id/swipeTo" 
      android:layout_width="wrap_content" 
      ... 

     </RelativeLayout> 
    </ScrollView> 
    </android.support.v4.widget.SwipeRefreshLayout> 
</LinearLayout>
