獲取Facebook用戶ID OnMapLongClickListener android

Question

我想通過意圖傳遞谷歌地圖中的facebook ID。

我有一個OnMapLongClickListener來獲取Latlng並通過意圖傳遞，我也想傳遞Facebook用戶ID ...我該怎么做？

OnMapLongClickListener

googlemap.setOnMapLongClickListener(new GoogleMap.OnMapLongClickListener() {
        @Override
        public void onMapLongClick(final LatLng latlng) {


            Intent intent = new Intent(MainActivity.this,newEvent.class);
            LatLng posicao = latlng;
            LatLng posicao1 = latlng;
            intent.putExtra("posicao", posicao);
            Bundle args = new Bundle();
            args.putParcelable("posicao1", posicao1);
            intent.putExtra("bundle", args);

            startActivity(intent);
        }
    });

我用這種方法檢索Facebook ID

  // METHODS FACEBOOK
public void onSessionStateChanged(final Session session, SessionState state, Exception exception){
    if(session != null && session.isOpened()){

        Toast.makeText(getBaseContext(),"Conectado!!", Toast.LENGTH_LONG).show();
        Request.newMeRequest(session, new Request.GraphUserCallback() {
            @Override
            public void onCompleted(GraphUser user, Response response) {
                if(user != null){  
                //final TextView tv = (TextView) findViewById(R.id.idface);

                    //tv.setText(user.getId());

                    Log.i("Script", "Usuário conectado " + user.getId());
                    getFriends(session);
                }
            }
        }).executeAsync();
    }
    else{
        Log.i("Script", "Usuario não conectado");
    }
}

我找到了解決方案...

即時通訊使用SharedPreferences

 SharedPreferences p = PreferenceManager.getDefaultSharedPreferences(context);
                    p.edit().putString("FB_ID", loginId).commit();

接着

    final SharedPreferences p = PreferenceManager.getDefaultSharedPreferences(context);
                final String username = p.getString("FB_ID", "");
Bundle args = new Bundle();
args.putString("facebook", username);
                intent.putExtra("facebook", args);

謝謝

我沒有Android或Java開發環境，因此可能無法編譯，但這應該可以給您一個想法。 Facebook用戶ID存儲在名為userId的字段中。 我將您的活動稱為MyActivity我假設您的代碼在活動中

class MyActivity extends Activity implements OnMapLongClickListener
{
    private String userId;

    @Override
    public void onMapLongClick(final LatLng latlng) {
        Intent intent = new Intent(MainActivity.this,newEvent.class);
        LatLng posicao = latlng;
        LatLng posicao1 = latlng;
        intent.putExtra("posicao", posicao);
        intent.putExtra("userId", userId);
        Bundle args = new Bundle();
        args.putParcelable("posicao1", posicao1);
        intent.putExtra("bundle", args);

        startActivity(intent);
    }

    public void onSessionStateChanged(final Session session, SessionState state, Exception exception){
    if(session != null && session.isOpened()){
        Toast.makeText(getBaseContext(),"Conectado!!", Toast.LENGTH_LONG).show();
        Request.newMeRequest(session, new Request.GraphUserCallback() {

            @Override
            public void onCompleted(GraphUser user, Response response) {
                if(user != null){  
                    //final TextView tv = (TextView) findViewById(R.id.idface);

                    userId = user.getId();

                    Log.i("Script", "Usuário conectado " + user.getId());
                    getFriends(session);
                }
            }
        }).executeAsync();
    }
    else{
        Log.i("Script", "Usuario não conectado");
    }
}

下面的代碼將按照您當前的方式從Activity內部的某個位置調用：

googlemap.setOnMapLongClickListener(this);
