Question

我在1个活动中动态加载按钮，然后加载按钮的onClick（）事件。在下面的活动中，我想显示与按钮相关的详细信息，例如，如果用户单击QUEST，它应仅显示QUEST详细信息，如果用户单击SRL，则应仅显示SRL详细信息。我无法得到。有人可以帮忙吗？

public void loadDescriptionList() {
    String url = "https://diagnostic.hisaabwaale.in/AndroidAppController/testGet";
    final ProgressDialog progressDialog = new ProgressDialog(TestDetails.this);
    progressDialog.setMessage("Loading Data...");
    progressDialog.show();
    StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    progressDialog.dismiss();
                    try {
                        obj = new JSONObject(response);
                        heroArray = obj.getJSONArray("list");
                        for (int i = 0; i < heroArray.length(); i++) {
                            heroObject = heroArray.getJSONObject(i);
                            TDescription hero = new TDescription(heroObject.getString("test_code"), heroObject.getString("test_description"), heroObject.getString("test_price"));
                            heroList.add(hero);
                        }
                        adapter = new ListViewAdapter(heroList, getApplicationContext());
                        listView.setAdapter(adapter);
                    } catch (JSONException e) {
                        progressDialog.dismiss();
                        e.printStackTrace();
                        Toast.makeText(getApplicationContext(), "No Records Found", Toast.LENGTH_LONG).show();
                    }
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    progressDialog.dismiss();
                    Toast.makeText(getApplicationContext(), "No Records Found", Toast.LENGTH_LONG).show();
                }

            }) {
        @Override
        protected Map<String, String> getParams() {
            Map<String, String> params = new HashMap<String, String>();
            params.put("franchise", franchise);
            return params;
        }
    };
    RequestQueue requestQueue = Volley.newRequestQueue(this);
    requestQueue.add(stringRequest);
}

后端api

  function testGet(){
  $response = array();
  $franchise = $this->input->post('franchise');
  $result = $this->testModel->testlist($franchise);
  if($result != 0){
    $response['status'] = 200;
    $response['list'] = $result;
  }else{
    $response['status'] = 201;
    $response['msg'] = 'No Records';
  }
  echo json_encode($response);
}

这是模型

public function testlist($franchise)
{
    $query = "SELECT t.id, t.franchise_id, t.test_code, t.test_description, t.test_price
            FROM `".$this->table."` as t
            WHERE t.franchise_id = ".$franchise;
   $result = $this->db->query($query);
   if($result->num_rows() > 0){
     return $result->result();
   }else{
     return 0;
   }

}

logcat的

Answer 1

Button QUEST= (Button) findViewById(R.id.QUEST);
QUEST.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
       Intent mIntent = new Intent(this, Example.class);
       Bundle extras = mIntent.getExtras();
       extras.putString('franchise', '8'); 

    }
});

Button SRL= (Button) findViewById(R.id.SRL);
SRL.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //Same as other, just different franchise
    }
});

当您打开下一个活动时：

String franchise = getIntent().getExtras().getString(franchise)

然后调用loadDescriptionList()也许它需要一个字符串？像

loadDescriptionList(String franchise)当您打开新活动时：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    loadDescriptionList(getIntent().getExtras().getString(franchise))
}

我假设loadDescriptionList()正在调用下一个活动。希望这有助于或引导您朝着正确的方向前进。

修改

您也可以使用下面的Bundle将值传递给下一个活动：

Intent mIntent = new Intent(this, Example.class); Bundle mBundle = new Bundle(); mBundle.putString(key, value); mIntent.putExtras(mBundle);

使用volley
