在我的应用程序中，当我要在ScrollView中选择文本时，要滚动我的Spinner到一个特定的TextView，该文本包含与使用Java的Android Studio中选定的Spinner文本相同的文本。 （您也可以检查图像）。在这里，我的微调器是动态的，而我的文本视图也是动态的。
我的代码-适用于微调
private void spinnerbind() {
JSONObject request = new JSONObject();
try {
request.put("action", "get_spinner");
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsArrayRequest = new JsonObjectRequest
(Request.Method.POST, url,request, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
JSONArray dataArray = response.getJSONArray("data");
if(response.optString("status").equals("1")){
goodModelArrayList = new ArrayList<>();
//JSONArray dataArray = obj.getJSONArray("data");
for (int i = 0; i < dataArray.length(); i++) {
PlayerModel playerModel = new PlayerModel();
JSONObject dataobj = dataArray.getJSONObject(i);
playerModel.setid(dataobj.getString("id"));
playerModel.setTitle(dataobj.getString("specialist"));
goodModelArrayList.add(playerModel);
}
for (int i = 0; i < goodModelArrayList.size(); i++){
names.add(goodModelArrayList.get(i).getTitle().toString());
}
spinnerArrayAdapter = new ArrayAdapter<String>(DoctorsActivity.this, simple_spinner_item, names);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // The drop down view
mySpinner.setAdapter(spinnerArrayAdapter);
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
PlayerModel playerModel = goodModelArrayList.get(position);
myid=playerModel.getId();
scrollView.scrollTo(0, 200);
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
//displaying the error in toast if occurrs
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_SHORT).show();
}
});
MySingleton.getInstance(this).addToRequestQueue(jsArrayRequest);
}
我的代码-用于文本绑定
public void detailsbind(){
JSONObject docrequest = new JSONObject();
try {
myrequest.put("action", "get_doctors");
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsArrayRequest = new JsonObjectRequest
(Request.Method.POST, url,myrequest, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
if(response.optString("status").equals("1")){
// Toast.makeText(getApplicationContext(),response.getString("data"), Toast.LENGTH_SHORT).show();
JSONArray dataSpecArray = response.getJSONArray("data");
LayoutInflater inflater = getLayoutInflater();
for (int k = 0; k < dataSpecArray.length(); k++) {
PlayerModel Specialist = new PlayerModel();
JSONObject specJSONobj = dataSpecArray.getJSONObject(k);
TextView text1 = new TextView(MyActivity.this);
text1.setText(specJSONobj.getString("specialist"));
mainlayout.addView(text1);
}
}else{
Toast.makeText(DoctorsActivity.this, response.optString("message"), Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
pDialog.dismiss();
//Display error message whenever an error occurs
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_SHORT).show();
}
});
// Access the RequestQueue through your singleton class.
MySingleton.getInstance(this).addToRequestQueue(jsArrayRequest);
}
最佳答案
scrollview.scrollTo(0, getRelativeTop(textView))
private int getRelativeTop(View textView) {
if (textView.getParent() == textView.getRootView())
return textView.getTop();
else
return textView.getTop() + getRelativeTop((View) textView.getParent());
}
