如何根据微调器选择在 edittext 中设置值？
how to set values in edittext as per spinner selection?
我有以下回复，
{
"1": {
"name": "abc",
"mobile_number": "123456789",
"address": "streetno3",
"landmark": "landmarksss",
},
"2": {
"name": "def",
"mobile_number": "123456789",
"address": "streetno3",
"landmark": "landmarksss",
},
"3": {
"name": "ghi",
"mobile_number": "23423423234",
"address": "abcdefgh",
"landmark": "usa",
},
"4": {
"name": "vvb",
"mobile_number": "55666655",
"address": "xvgghg",
"landmark": "fghgh",
},
"5": {
"name": "test",
"mobile_number": "77699231010",
"address": "pune",
"landmark": "fghgh",
}
}
我正在获取 spinner 中的所有名称，直到这里它工作正常，现在我尝试的是默认情况下我有 abc selected，如果我 select 从微调器测试那么我如何在我的 edittexts 中显示他的详细信息，简而言之，根据名称 selection 我正在尝试在 edittext
中获取和设置详细信息
Java代码

你有两个选择
1.Create 自定义微调适配器，如下例
CustomAdapter.java

data = objects;
res = resLocal;
/*********** Layout inflator to call external xml layout () **********************/
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public View getDropDownView(int position, View convertView,ViewGroup parent) {

}
@Override

return getCustomView(position, convertView, parent);
}
// This funtion called for each row ( Called data.size() times )
public View getCustomView(int position, View convertView, ViewGroup parent) {
/********** Inflate spinner_rows.xml file for each row ( Defined below ) ************/
View row = inflater.inflate(R.layout.spinner_rows, parent, false);
/***** Get each Model object from Arraylist ********/
tempValues = null;
tempValues = (SpinnerModel) data.get(position);
TextView label = (TextView)row.findViewById(R.id.company);
TextView sub = (TextView)row.findViewById(R.id.sub);
ImageView companyLogo = (ImageView)row.findViewById(R.id.image);
if(position==0){
// Default selected Spinner item
label.setText("Please select company");
sub.setText("");
}
else
{
// Set values for spinner each row
label.setText(tempValues.getCompanyName());
sub.setText(tempValues.getUrl());
companyLogo.setImageResource(res.getIdentifier

return row;

}
- 创建一个 bean 类型数组列表并按照您在 arrallstates 中存储的相同顺序存储所有详细信息，在微调器的 onItemSelected 方法中您总是获得位置并且在两个数组列表中您具有相同的数据位置所以现在获取数据来自 bean 类型数组列表，然后根据需要进行设置
这种数据最好做成POJOclass，方便数据管理。但是，如果您还没有使用 POJO class，那么现在您可以从其位置获取微调器数据并将其拆分以在 EditText 中打印。
假设如果您在微调器中的 ItemSelected 上的 data 字符串中获取数据，您可以按照以下代码将其打印在 edittext 中。
String split[]=data.split(",");
String name=split[0];
String mobile=split[1];
我有以下回复，
{
"1": {
"name": "abc",
"mobile_number": "123456789",
"address": "streetno3",
"landmark": "landmarksss",
},
"2": {
"name": "def",
"mobile_number": "123456789",
"address": "streetno3",
"landmark": "landmarksss",
},
"3": {
"name": "ghi",
"mobile_number": "23423423234",
"address": "abcdefgh",
"landmark": "usa",
},
"4": {
"name": "vvb",
"mobile_number": "55666655",
