フラグメントのアクティビティのリストビュー

Question

アクティビティでクリック可能なリストビューがあります。私が望むのは、リストからクリックすると、フラグメントに移動します。それがどのように行われたのか誰にも分かりますか？

また、ユーザーがリストからクリックすると、新しいアクティビティが開きます。

編集：ここに私のコードがあります。

searchviewとlistviewが表示され、クリック可能です。しかし、ユーザーがリストからクリックしてフラグメントやアクティビティにどのように移動したかはわかりません。

[your_list_view].setOnItemClickListener(mDeviceClickListener); 

その後方法定義：：、あなたがでframeLayoutを作成する必要があり、あなたのactivity_main.xmlで

private AdapterView.OnItemClickListener mDeviceClickListener = new AdapterView.OnItemClickListener() { 
@SuppressWarnings("unchecked") 
public void onItemClick(AdapterView<?> av, View v, int arg2, long arg3) { 
    String info = ((TextView) v).getText().toString(); //text of position selected 
} }; 

をあなたがコードであなたのListViewのためのclickListenerを定義する必要があります:(

Answer 1

ファーストフラグメントのロード先：

ListView用に作成したメソッドの中で、このようなあなたのフラグメントを膨らませる必要があります。

public class FragmentMain extends Fragment { 

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    //returning our layout file 
    //change R.layout.yourlayoutfilename for each of your fragments 
    final View view = inflater.inflate(R.layout.yourlayoutfilename, container, false); 


    return view; 
} 

@Override 
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { 
    super.onViewCreated(view, savedInstanceState); 
    //you can set the title for your toolbar here for different fragments different titles 
    getActivity().setTitle("Main"); 


} 
} 

そして、あなたがしたい場合：

Fragment newFragment = new YourFragmentClass(); 
FragmentTransaction transaction = this.getSupportFragmentManager().beginTransaction(); 
transaction.replace(R.id.content_frame, newFragment); 
transaction.addToBackStack(null); 
transaction.commit(); 

あなたがフラグメントを処理するとき、「YourFragmentClassは（）」クラスであることを確認してください、このクラスでは、このようなものですそれが役立ちます:)

startActivity(new Intent(CurrentActivity.this,DestinationActivity.class)); 

はホープ：アクティビティを変更するには、あなたは自分のListViewのonClickListenerにこのコードを配置する必要があります
