안드로이드 php 연동 클립보드 복사하기

Question

안드로이드랑 php랑 엮어서 만들고 있는데요

password1버튼을 클릭하면 php에 있는 password1을 읽어 클립보드에 저장시키고 싶습니다.

그런데 어떤 변수를 어떻게 넣어야 하는지 잘 모르겠습니다. 

도와주세요 ㅠㅠ

public class adminActivity extends Activity {

    String myJSON;

    private static final String TAG_RESULTS="result";
    private static final String TAG_PASSWORD1 = "password1";

    JSONArray peoples = null;

    Button Password1;
    Button backButton;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_admin);

        getData("http://192.168.10.101/admin.php");

        Password1 = (Button) findViewById(R.id.password1);
        backButton = (Button) findViewById(R.id.backButton);

        Password1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                ClipboardManager clipboardManager = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
                String txt = (getData(password1)).toString();
                clipboardManager.setText(txt);
            }
        });

        backButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent resultIntent = new Intent();

                setResult(RESULT_OK, resultIntent);
                finish();
            }
        });

    }

    protected void showList(){
        try {
            JSONObject jsonObj = new JSONObject(myJSON);
            peoples = jsonObj.getJSONArray(TAG_RESULTS);

            for(int i=0;i<peoples.length();i++){
                JSONObject c = peoples.getJSONObject(i);
                String password1 = c.getString(TAG_PASSWORD1);

                HashMap<String,String> persons = new HashMap<String,String>();

                persons.put(TAG_PASSWORD1, password1);

            }

        } catch (JSONException e) {
            e.printStackTrace();
        }

    }

    public void getData(String url){
        class GetDataJSON extends AsyncTask<String, Void, String> {

            @Override
            protected String doInBackground(String... params) {

                String uri = params[0];

                BufferedReader bufferedReader = null;
                try {
                    URL url = new URL(uri);
                    HttpURLConnection con = (HttpURLConnection) url.openConnection();
                    StringBuilder sb = new StringBuilder();

                    bufferedReader = new BufferedReader(new InputStreamReader(con.getInputStream()));

                    String json;
                    while((json = bufferedReader.readLine())!= null){
                        sb.append(json+"\n");
                    }

                    return sb.toString().trim();

                }catch(Exception e){
                    return null;
                }



            }

            @Override
            protected void onPostExecute(String result){
                myJSON=result;
                showList();
            }
        }
        GetDataJSON g = new GetDataJSON();
        g.execute(url);
    }

}
