I'm attempting to set the text color in a CustomAdapter class by overriding the View. The code seems to run but the phone screen displays nothing. Any suggestions?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
prefs = PreferenceManager.getDefaultSharedPreferences(LogCat.this);
String logLevel = prefs.getString("dirLogCat", "");
setContentView(R.layout.log_cat);
ListView lv1 = (ListView) findViewById(R.id.listView1);
ArrayAdapter<String> arrayAdapter =
new ArrayAdapter<String>(this, R.layout.text_list, log);
try {
Process process = Runtime.getRuntime().exec(new String[] {"logcat", "-d"});
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(process.getInputStream()));
while ((line = bufferedReader.readLine()) != null){
if (line.contains(" " + logLevel + " ")){
//log.add(line);
log.add(line.substring(6, 14) + " " + line.substring(31, line.length()));
}
}
CustomAdapter adapter = new CustomAdapter(log, this, "V");
lv1.setAdapter(arrayAdapter);
adapter.notifyDataSetChanged();
}
catch (IOException e) {}
}
public class CustomAdapter extends BaseAdapter {
private Context ctx;
CustomAdapter (ArrayList<String> data, Context context, String log) {
this.ctx = context;
this.getView(0, new View(context), null);
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
LayoutInflater inflator = (LayoutInflater)ctx.getSystemService(LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.text_list, null);
TextView textView = (TextView) v.findViewById(R.id.logText);
textView.setTextColor(Color.CYAN);
return textView;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return 0;
}
#Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
}
}
EDIT:
This did it:
public class CustomAdapter extends BaseAdapter {
private Context ctx;
private ArrayList<String> children;
CustomAdapter (ArrayList<String> data, Context context, String log) {
this.ctx = context;
System.out.println("Cyan1");
this.children = data;
this.getView(0, new View(context), null);
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
LayoutInflater inflator = (LayoutInflater)ctx.getSystemService(LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.text_list, null);
TextView textView = (TextView) v.findViewById(R.id.logText);
System.out.println("Cyan");
textView.setTextColor(Color.CYAN);
for(int i = 0; i < log.size(); i++){
textView.setText(children.get(i));
}
return textView;
}
You're setting the wrong adapter in the list?
CustomAdapter adapter = new CustomAdapter(log, this, "V");
lv1.setAdapter(arrayAdapter); //<---- arrayAdapter instead of adapter?
adapter.notifyDataSetChanged();

getSystemService() is method of context, you are calling it on instance of adapter.

This my code i am able to display the value after Jason parsing in this line System.out.println(Id + "" + Designation + ""
+ EmployeeName);
But i am unable to print data in Listview there is Error coming while i have created
Datamodel
public class RowItem {
public RowItem(String title, String desc) {
this.title = title;
this.desc = desc;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDesc() {
return desc;
}
public void setDesc(String desc) {
this.desc = desc;
}
private String title;
private String desc;
}
I have create adapter which i s extending from Base adapter that work fine can u please tell me how to bind value and display in list view after Json Parsing please suggest me i m trying to Implement .
Use Custom Adapter for binding your JSON data to your Listview like below :
public class ListViewAdapterForLead extends BaseAdapter {
Context context;
LayoutInflater inflater;
ArrayList<SpinnerNavItem> data;
TextView txtText;
public ListViewAdapterForLead(Context context,ArrayList<SpinnerNavItem> arraylist) {
this.context = context;
data = arraylist;
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int index) {
return data.get(index);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.row_lead, null);
}
txtText = (TextView) convertView.findViewById(R.id.textLeadMenu);
txtText.setText(data.get(position).getTitle());
return convertView;
}
public View getDropDownView(int position,View convertView,ViewGroup parent){
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.row_lead, null);
}
txtText = (TextView) convertView.findViewById(R.id.textLeadMenu);
txtText.setText(data.get(position).getTitle());
return convertView;
}
}
bind your values in the getView() method of your custom adapter.
You should set the data after the background task gets completed.
* First try to set list adapter in onPostExecute() method.
* Make sure all the details in your model gets filled.
* Make use of getView() method in your Adapter class to parse the data.
For sample code for ListView with BaseAdapter, refer the below link
http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/
You forgot one thing,this is why the List is empty
Add the parsed data to your List
//initialize your list here
rowItems = new List<RowItems>();
for (int i = 0; i <= _jarray.length(); i++) {
JSONObject _obj = _jarray.getJSONObject(i);
RowItemsr = new RowItems();
Id = _obj.getString("Id");
Designation = _obj.getString("Designation");
EmployeeName = _obj.getString("EmployeeName");
System.out.println(Id + "" + Designation + ""
+ EmployeeName);
// you must create an object and add it to your list
r.setTitle(EmployeeName);
r.setDesc(Designation);
rowItems.add(r);
}
This is what you need
I Have 2D Array and this 2D Array has Strings. I would like to know How to Display the Strings in ListView?how to scroll both vertically and horizontally?
String[][] board = new String[][] {{"1","10","100"},{"hi0","1hello","test"},{"test31","test32","test43"}};
It seem to be you are asking basic things, How to use ListView. please check it you will get all about ListView.
Android ListView and ListActivity
It is to display two-d array in list view.Here's my source code in which i have implemented 2-d array in list view
My Adapter class:-
public class MyArrayAdapter extends ArrayAdapter<List>{
QuickActionDemo quickActionDemo;
public Activity context;
public List<List> list;
int CAMERA_PIC_REQUEST=10;
private int selectedPos = -1;
int clickPosition,rowPosition;
Camera camera;
private static final String TAG = "CameraDemo";
public MyArrayAdapter(Activity context,List<List> list) {
super(context,R.layout.attach_pic,list);
this.context = context;
this.list = list;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position+1;
}
static class ViewHolder {
public TextView tv1,tv2,tv3;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View rowView = null;
final ViewHolder holder = new ViewHolder();
if (convertView == null) {
LayoutInflater inflator = context.getLayoutInflater();
rowView = inflator.inflate(R.layout.attach_pic, null);
holder.tv1 = (TextView) rowView.findViewById(R.id.defectpic);
holder.tv2 = (TextView) rowView.findViewById(R.id.no_of_uploded_pics);
holder.tv3 = (TextView) rowView.findViewById(R.id.camera);
holder.tv3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// Intent in = new Intent(getContext(),QuickActionDemo.class);
// context.startActivityForResult(in,0);
}
});
rowView.setTag(holder);
List itemVal1 = (List)getItem(position);
String st1 = (String)itemVal1.get(0);
holder.tv1.setText(st1);
List itemVal2 = (List)getItem(position);
String st2 = (String)itemVal2.get(1);
holder.tv2.setText(st2);
} else {
rowView = convertView;
((ViewHolder) rowView.getTag()).tv1.setTag(list.get(position));
((ViewHolder) rowView.getTag()).tv2.setTag(list.get(position));
((ViewHolder) rowView.getTag()).tv3.setTag(list.get(position));
}
return rowView;
}
#Override
public int getItemViewType(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public int getViewTypeCount() {
// TODO Auto-generated method stub
return list.size();
}
}
Here's my activity class:-
public class MyActivity extends ListActivity {
Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
// requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); // to hide the virtual keyboard
setContentView(R.layout.defect_pic_listview);
try{
ArrayAdapter<List> adapter = new MyArrayAdapter(this,makeList());
setListAdapter(adapter);
}
}
private List<List> makeList(){
List<List> all = new ArrayList();
String[] newArray1 = {"Defect Picture1", "2"};
List<String> newListObject1 = Arrays.asList(newArray1);
String[] newArray2 = {"Defect Picture2","1"};
List<String> newListObject2 = Arrays.asList(newArray2);
String[] newArray3 = {"Defect Picture3","4"};
List<String> newListObject3 = Arrays.asList(newArray3);
String[] newArray4 = {"Defect Picture4","1"};
List<String> newListObject4 = Arrays.asList(newArray4);
String[] newArray5 = {"Defect Picture5","3"};
List<String> newListObject5 = Arrays.asList(newArray5);
all.add(newListObject1);
all.add(newListObject2);
all.add(newListObject3);
all.add(newListObject4);
all.add(newListObject5);
return all;
}
}
Creating a model as an inner class always works well.
Good way to store any number of items.
public class ActivityClass extends Activity {
...
ArrayList<ValuesModel> listViewValues = new ArrayList<ValuesModel>();
listViewValues.add(new ValuesModel("row title", "row details"));
ListViewAdapter listAdapter = new ListViewAdapter(this, listViewValues);
((ListView) findViewById(android.R.id.list)).setAdapter(listAdapter);
...
public class ValuesModel {
private String rowTitle;
private String rowDetails;
public ValuesModel(String rowTitle, String rowDetails) {
this.rowTitle = rowTitle;
this.rowDetails = rowDetails;
}
public String getRowTitle() {
return rowTitle;
}
public String getRowDetails() {
return rowDetails();
}
}
Then inside of your list adapter,
public class ListViewAdapter extends ArrayAdapter<ActivityClass.ValuesModel> {
private ArrayList<ActivityClass.ValuesModel> mValues;
...
#Override
public View getView(int position, View convertView, ViewGroup parent) {
...
//here whenever you need to retrieve your values, just say:
// mValues.get(position).getRowTitle();
// mValues.get(position).getRowDetails();
//if you use a viewholder pattern, you can do this:
viewHolder.rowTitle = (TextView) convertView.findViewById(R.id.row_title_textview);
viewHolder.rowTitle.setText(mValues.get(position).getRowTitle());
...
}
}
My ListView consist an ImageView and a TextView I need to get the Text from the TextView.
int the position of my list where I press (onItemClick).
How can I do that?
The 1 class have a Button then when you press I moving to the next activity (CountryView)
and expect to get back from the next activity with a text (name of the selected Country)
The 2 classes have a ListView (ImageView and TextView) the data is getting from a database and showing on the ListView.
My problem is to get back to the 1 class the selected name of the country.
Thanks so much for helping!!!

When you add things to the list, you can add hashmaps to the arraylist which the adapter looks at. Then you can grab the values which are name value pairs.
I think you want to get the position of the list you clicked, Its simple you can use OnItemClickListener as follows
YourList.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
int position=arg2;
// where position is the clicked position
} }
If you stored your data in String array pass this position say array[position] to string array you can get the Text..
