嗨我需要获得动态字符串并需要存储在textview中（id是在xml中的trainer_title_text）。这该怎么做？ json的响应输出是： 1.私人培训师2.政府培训师。如何在不改变xml对齐的情况下在textview中指定字符串列表？
这是代码：
public class DynamicTextView extends Fragment {
private TextView TitleTypes;
private String StrDescription;
private RelativeLayout relative;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.trainers_certification,
container, false);
JSONArray jsonTypePrice=jsonData.getJSONArray("trainer_type_items");
for (int i = 0; i < jsonTypePrice.length(); i++) {
JSONObject object = jsonTypePrice.getJSONObject(i);
strType=object.getString("type");
//here i am getting type as 1.private Test 2.public Test
strCost=object.getString("cost");
Log.e("service call types", strType);
}
LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
textView.setLayoutParams(lparams);
relative.addView(textView);
textView.setText(strType);
I used like this but it's always setting only one data.
Output is:
private Test
Here is xml: where id is trainer_title_text i need to assign list of strings in vertical.

答案 0 :(得分：0)
使用StringBuilder收集以这种方式显示所需的所有信息：
JSONArray jsonTypePrice=jsonData.getJSONArray("trainer_type_items");
StringBuilder builder = new StringBuilder();
for (int i = 0; i < jsonTypePrice.length(); i++) {
JSONObject object = jsonTypePrice.getJSONObject(i);
strType=object.getString("type");
// Note the new-line we're adding at the end
builder.append(strType).append("\n");
strCost=object.getString("cost");
Log.e("service call types", strType);
}
然后只需将我们构建的多行文本添加到textView。
textView.setText(builder.toString());
