I am having trouble creating a Custom Adapter that will allow me to use several different views in a ListView depending on the results from JSON data.
The JSON has 5 different types of data fields and each one needs to have a separate layout. For example, the "text" field needs a TextView and then a EditText element and the "bool" field needs a TextView and a Switch element.
The JSON data could include any variation of the 5 data fields so I can't create a static layout.
I have created a separate xml file for each type of data field.
Below is the current state of my Custom Adapter with some JSON hard coded into it.
Thanks in advance!
public class JobAdapter extends ArrayAdapter<String> {
private static final String JSON_STRING = "{\"title\":\"Unity Gain Amp install\",\"submit\":\"http://dci-services.decisiveinc.net/ampinstall/\n" +
"\n" +
"Submit\",\"sections\":[{\"title\":\"Unity Gain Amp \n" +
"\n" +
"Install\",\"fields\":[{\"name\":\"TechNumber\",\"type\":\"number\",\"label\":\"Tech \n" +
"\n" +
"Number\",\"required\":true,\"stored\":true},{\"name\":\"AmpSerial\",\"type\":\"string\",\"label\":\"Amp Serial \n" +
"\n" +
"#\",\"required\":true,\"stored\":false},{\"name\":\"Account\",\"type\":\"number\",\"label\":\"Account \n" +
"\n" +
"#\",\"required\":true,\"stored\":false}]},{\"title\":\"Reason For Amp \n" +
"\n" +
"Install\",\"fields\":[{\"name\":\"Reason\",\"type\":\"select\",\"label\":\"Reason\",\"required\":true,\"stored\":f\n" +
"\n" +
"alse,\"options\":[{\"key\":\"1\",\"label\":\"Low receive power\"},{\"key\":\"2\",\"label\":\"High \n" +
"\n" +
"Transmit \"},{\"key\":\"3\",\"label\":\"Both\"},{\"key\":\"4\",\"label\":\"Replacement\"}\n" +
"\n" +
"]},{\"name\":\"OldAmpSN\",\"type\":\"string\",\"label\":\"If Replacement: Old Amp \n" +
"\n" +
"SN\",\"required\":false,\"stored\":false}]}]}";
