create relative layout object from it layout id, then you can add it as below
relativeLayout = findViewById(R.id.yourRelativeLayoutId);
relativeLayout.addView(yourView);

Listview or recyclerview is best for practice but as you want to use textview, you can use like this in your code:
RelativeLayout relativeLayout =
(RelativeLayout) findViewById(R.id.rootlayout);
TextView textView = new TextView(this);
textView.setText("Hey, I am TextView");
relativeLayout.addView(textView);

appending a textview to relativelayout is pretty simple.
just use
TextView textview = new TextView(this);
textview.setText("Text");
relativelayoutobject.addView(textview);
to setup the position use
textview.setLayoutParams(thelayoutparams)
But if you use big database, please, use 'TableLayout' instead of your method due to performance reasons.

Define relative layout in your xml layout. Add multiple textview programmatic ally like this-
RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout);
//use a for loop to define multiple textView in RelativeLayout
//length is no. of textView you required
for (int i = 0; i < length; i++) {
TextView tv = new TextView(relativeLayout.getContext());
tv.setText("Text from sqlite database");
tv.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
relativeLayout.addView(tv);
}

Trying to set the marker on the current position gives me nullpointer exception

I have done the following things in my program:
I am generating some Buttons programmatically in my MenuItemsActivity class. I have a Listview in the xml of the MenuItemsActivity class.
When I click on the button the appropriate contents get loaded in the Listview. I just refresh the activity i.e I am using the same Listview to load different contents based on the button which is clicked.
I want to do the following:
When the Button is clicked I want to change the background of the button to 'blue_tab` and maintain that same color when the same activity reloads. Can anyone guide me step by step what to do, as I am a newbie to Android.

You can use PreferenceManager to save data and use it when the app is reloaded/restarted
sample:
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String text = tv1.getText().toString();
Log.e("text message", "" + text);
if(PreferenceManager.getDefaultSharedPreferences(MenuItemsActivity.this).getString("button", "").length != 0)
tv1.setBackgroundDrawable(getResources().getDrawable(R.drawable.blue_tab));
else
{
Editor editor = PreferenceManager.getDefaultSharedPreferences(MenuItemsActivity.this).edit();
editor.putString("button", "1");
editor.commit();
tv1.setBackgroundDrawable(getResources().getDrawable(R.drawable.blue_tab));
}
Toast.makeText(MenuItemsActivity.this, "clicked", 1000)
.show();
Intent i = new Intent(MenuItemsActivity.this,
MenuItemsActivity.class);
i.putExtra("category name", "" + text);
finish();
startActivity(i);
}

Displaying json data in ListView?

In my android project, I have a ListView which populates the data entered by the user on runtime. Along with this, I want to show some data from an existing JSON file. So I parsed this JSON file and stored it in a String. How can I show both of these in my application?Can I use same the Listview for both ?
This is my code
// Reading text file from assets folder
StringBuffer sb = new StringBuffer();
BufferedReader br = null;
try
{
br = new BufferedReader(new InputStreamReader(getAssets().open(
"jsonshoutdata.txt")));
String temp;
while ((temp = br.readLine()) != null)
sb.append(temp);
}
catch (IOException e)
{
e.printStackTrace();
}
finally
{
try
{
br.close(); // stop reading
}
catch (IOException e)
{
e.printStackTrace();
}
}
String myjsonstring = sb.toString();
// Try to parse JSON
try {
//urlist = new ArrayList<HashMap<String, String>>();
// Creating JSONObject from String
JSONObject jsonObjMain = new JSONObject(myjsonstring);
// Creating JSONArray from JSONObject
JSONArray jsonArray = jsonObjMain.getJSONArray("message");
ArrayList<String> messages = new ArrayList<String>();
for (int i = 0; i < jsonArray.length(); i++) {
// Creating JSONObject from JSONArray
JSONObject jsonObj = jsonArray.getJSONObject(i);
// Getting data from individual JSONObject
String message = jsonObj.getString("msg");
messages.add(message);
}
This is my customList adapter for json data
customtest adapter = new customtest(Single.this,R.layout.list_single_shout_single,messages);
ListView list = (ListView)findViewById(R.id.list_shout_screen);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(Single.this, "TEST.........", Toast.LENGTH_SHORT).show();
}
});
}
catch (JSONException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
This is my customList adapter which i already have
final CustomListSingle adapter1 = new CustomListSingle(Single.this, web1,web,rounded,imageId2,imageId3,result1,result2);
//CustomListSingle adapter = new CustomListSingle(Single.this, web1,web,rounded,imageId2,imageId3,result1,result2);
list_shout_screen=(ListView)findViewById(R.id.list_shout_screen);
list_shout_screen.setAdapter(adapter1);
//list_shout_screen.setAdapter(adapter);
list_shout_screen.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id)
{
TextView txtTitle = (TextView)findViewById(R.id.txt);
txtTitle.length();
Toast.makeText(Single.this, "Length is " + txtTitle.getMeasuredWidth(), Toast.LENGTH_SHORT).show();
txtTitle.getTextSize();
}
}
);
//Button click activity......
final EditText et = (EditText)findViewById(R.id.EditText1);
final Button imb=(Button)findViewById(R.id.btn_send);
imb.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View arg0)
{
String str = et.getText().toString();
web1.add(str);
Toast.makeText(Single.this, "You entered...."+str, Toast.LENGTH_SHORT).show();
adapter1.notifyDataSetChanged();
scrollMyListViewToBottom();
et.setText(" ");
}
This is my adapter class
public CustomListSingle(Activity context,ArrayList<String> web,ArrayList<String> web1,Bitmap rounded,Integer[] imageId2,Integer[] imageId3,Bitmap image1,Bitmap image)
{
super(context, R.layout.list_single_shout_single, web);
this.context = context;
this.web = web;
this.web1 = web1;
//this.imageId1 = imageId1;
this.rounded=rounded;
this.imageId2 = imageId2;
this.imageId3 = imageId3;
this.image=image;
this.image1=image1;
}
#Override
public View getView(int position, View view, ViewGroup parent)
{
LayoutInflater inflater = context.getLayoutInflater();
View rowView= inflater.inflate(R.layout.list_single_shout_single, null, true);
/*msg*/
TextView txtTitle = (TextView) rowView.findViewById(R.id.txt);
//pic
ImageView imageView1 = (ImageView) rowView.findViewById(R.id.img1);
ImageView imageView3 = (ImageView) rowView.findViewById(R.id.img);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.RIGHT;
txtTitle.setLayoutParams(params);
txtTitle.setText(web.get(position));
txtTitle.setBackgroundResource(R.drawable.test);
imageView1.setImageBitmap(rounded);
imageView3.setImageBitmap(image1);
return rowView;
}
}
Method for making images circular
public static Bitmap getCircularBitmapFrom(Bitmap bitmap)
{
if (bitmap == null) {
return null;
}
float radius = bitmap.getWidth() > bitmap.getHeight() ? ((float) bitmap
.getHeight()) / 2f : ((float) bitmap.getWidth()) / 2f;
if (radius < 0) {
radius = 0;
}
Bitmap canvasBitmap = Bitmap.createBitmap(bitmap.getWidth(),
bitmap.getHeight(), Bitmap.Config.ARGB_8888);
BitmapShader shader = new BitmapShader(bitmap, TileMode.CLAMP,
TileMode.CLAMP);
Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setShader(shader);
Canvas canvas = new Canvas(canvasBitmap);
canvas.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2,
radius, paint);
return canvasBitmap;
}
And this
Bitmap bmp=BitmapFactory.decodeResource(getResources(), R.drawable.white);
Bitmap bmp1=BitmapFactory.decodeResource(getResources(), R.drawable.prof_pic_a);
Bitmap images = BitmapFactory.decodeResource(getResources
(),R.drawable.prof_pic_a);
Bitmap rounded;
rounded=getCircularBitmapFrom(images);
result1=getCircularBitmapFrom(bmp);
result2=getCircularBitmapFrom(bmp1);

suppose you have this arraylist
ArrayList<String> messages = new ArrayList<String>(); //add this line on top so it will be accessed globally
and your button code
final Button imb=(Button)findViewById(R.id.btn_send);
imb.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View arg0)
{
String str = et.getText().toString();
messages.add(str);
Toast.makeText(Single.this, "You entered...."+str, Toast.LENGTH_SHORT).show();
adapter1.notifyDataSetChanged();
scrollMyListViewToBottom();
et.setText(" ");
adapter1.notifyDataSetChanged(); //list is the name of your listview
}
call notifyDataSetChanged whenever you want to update your listview(after adding data in your arraylist)

Correct item is not selected in Listview

I am using this Tutorial for Creating a custom listview with radio button. In this tutorial when we click the item in the list then color of item change.

Your Adapter class
public class GoArrayAdapter extends ArrayAdapter<GoModelAll> {
private final Context context;
ImageLoader imgLoader;
private final ArrayList<GoModelAll> values;
DataHelper dh;
public GoArrayAdapter(Context context,
ArrayList<GoModelAll> values) {
super(context, R.layout.go_row, values);
this.context = context;
this.values = values;
imgLoader = new ImageLoader(context);
dh = new DataHelper(context);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.go_row, parent, false);
/** Get view over here.. */
GoModelAll asm = values.get(position);
TextView title = (TextView) rowView.findViewById(R.id.go_tv);
ImageView business_logo = (ImageView) rowView.findViewById(R.id.go_image);
ImageView go_red = (ImageView)rowView.findViewById(R.id.go_red);
if(asm.isSeen)
{
go_red.setVisibility(View.INVISIBLE);
}
/**Set view over here..*/
title.setText(asm.title);
// Loader image - will be shown before loading image
int loader = R.drawable.image_not_available;
String image_url = asm.thumsrc;
imgLoader.DisplayImage(image_url, loader, business_logo);
return rowView;
}
}
At last your Model class
public class GoModelAll {
public String description = "";
public String excert = "";
public String thumsrc = "";
public String title = "";
public int postid = 0;
public boolean isSeen = false;
}

Show us your adapter code as well and try not to change an item of list view from setOnItemClickListener instead change your data and notify adapter to refresh the view.
Set this as background to your list item :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#color/white" />
<item android:color="#color/black" />
</selector>

How to get tablerow id dynamically in android?

Hello, my old code is working, but the problem is that when i am clicking tablerow it call another activty, but it not set that table row data but it setting last array data to that activity.
Means it set the last array value to next screen activity.
for ( j = 0; j < dataListfeture.size(); j++)
{
HashMap<String, String> hm = new HashMap<String, String>();
hm = dataListfeture.get(j);
final TableRow tblrow = new TableRow(MainScreen.this);
final View rowView = inflater.inflate(R.layout.featuredrow, null);
tblrow.setId(j);
tblrow.getId();
featuredName = (TextView) rowView.findViewById(R.id.xxName);
featuredDistance = (TextView) rowView.findViewById(R.id.xxDistance);
featuredVeneType = (TextView) rowView.findViewById(R.id.xxVeneType);
featuredPhone = (TextView) rowView.findViewById(R.id.xxPhone);
featuredAddress = (TextView) rowView.findViewById(R.id.xxAddress);
Drawable image = ImageOperations(MainScreen.this, hm.get("url"), "image.jpg");
featuredImage = (ImageView) rowView.findViewById(R.id.xxdImage);
featuredImage.setImageDrawable(image);
featuredName.setText("" + hm.get("name"));
featuredDistance.setText("" + hm.get("distance") + " mi");
featuredVeneType.setText("" + hm.get("venuetype"));
featuredPhone.setText("" + hm.get("phonenumber"));
featuredAddress.setText("" + hm.get("address"));
mapnamelist = hm.get("name");
mapvenuelist = hm.get("venuetype");
mapothervenuelist = hm.get("othervenuetype");
mapaddresslist= hm.get("address");
mapcitylist= hm.get("city");
mapstatelist= hm.get("state");
tblrow.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
final ProgressDialog progDailog = ProgressDialog.show(MainScreen.this, null, "Loading ....", true);
final Handler handler = new Handler()
{
public void handleMessage(Message msg)
{
System.out.println("search");
Intent myIntent = new Intent(MainScreen.this, xxxxscreen.class);
startActivity(myIntent);
MainScreen.this.finish();
progDailog.dismiss();
}
};
new Thread()
{
public void run()
{
try
{
System.out.println();
handler.sendEmptyMessage(1);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}.start();
}
});

Create an int array of id say array_id[] and after setting id to table row add that id to array_id[] also like
tblrow.setId(j);
array_id[j] = j;
And in onClick method do this:
for(int i = 0;i< array_id.length;i++)
{
TableRow tbl_row = (TableRow) findViewById(i);
if(v.getId() == array_id[i])
{
/** Perform your Operations */
}
}
