Google PlayサービスでOnMyLocationButtonClickを使用するには

Question

Androidプログラミングでは新しいですが、collapsingToolbarLayoutを使用するフラグメントクラスでMyLocationボタンを使用することはできません。このコード行でMylocationボタンを追加しました：

googleMap.setMyLocationEnabled(true); 

私は、公式ドキュメントを読んで、それは言った：

をユーザーがボタンをクリックすると、それがわかっている場合、カメラは、デバイスの現在の位置にマップを中央に配置します。

ボタンが表示されますが、私の場合はボタンを押すと何も起こりません。

どこが間違っていますか？

これは私のフラグメントのクラスコードです：

... 
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 
...

Answer 1

ツールバーは、 "私の場所" ボタンと重なります。 GoogleMap.setPadding（）メソッドを使用して地図の端にパディングを追加することができます。地図はコンテナ全体を塗りつぶしますが、テキストとコントロールの位置付け、地図のジェスチャ、カメラの動きは、より小さな空間に配置されている」 （see Maps Documentation)

mMap.setPadding(200, 200, 200, 200); 

それとも、追加しようとすることができます。あなたのxmlで

android:layout_marginTop="100dp" 

を、MapFragmentため

Answer 2

私はそれがこのコードでonMapReady方法でMyButtonという位置を変える解決：

// Get the button 

View locationButton = ((View) mapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2")); 

RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) 
       locationButton.getLayoutParams(); 

layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0); 
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE); 
layoutParams.setMargins(0, 0, 30, 30);
