May be you could use a Dialog where you can add Buttons to show the keys, and this pops up when a key is pressed on EditText. You can pass the reference of EditText to this dialog class, and in button click event fetch the text of button and set it to edit text.

Deepika,

You can have a look on this. In this example I am using a numeric key pad, the only change what you need is to make a alphabetic/alphanumeric key pad.

main.xml
-----------


numericpopup.xml
---------------------

where to use this code?

public class NumbreKeyboardActivity extends Activity {
/** Called when the activity is first created. */
private EditText _etText;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
_etText=(EditText)this.findViewById(R.id.EditText01);
_etText.setOnTouchListener(new View.OnTouchListener(){

public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if(event.getAction()==MotionEvent.ACTION_DOWN){
EditText et=(EditText)v;
et.setInputType(InputType.TYPE_CLASS_NUMBER);
NumericCalculator ncp=new NumericCalculator(NumbreKeyboardActivity.this,et);
ncp.show();
return true;
}
return false;
}

});
}
}
it will be stored in separate folder or this is continuation of the code?

This is the main activity class. For your easier understanding I have pasted everything under different code tags.

1. Create a project and name the Activity class name NumbreKeyboardActivity. Copy the code of the the class to this.
2. Add another class to the same project, i.e NumericCalculator, code is already there.
3. Moidfy the contents of main.xml
4. Add another xml file named numericpopup.xml, code is already given.
5. Build and run the project.

Do you mean, when the tab is tapped, the keyboard pops up? Can we have click events for tab, not very sure about this, probably a tab just represents an activity, correct me if I am wrong, however positioning the dialog looks possible.

Probably in your code you just need to include this part.

package com.example.addition;


import android.app.Activity;

import android.os.Bundle;

import android.widget.EditText;

import android.widget.TextView;

import android.widget.Button;

import android.view.View;


public class AdditionActivity extends Activity
{
EditText amount1;
EditText amount2;
TextView tt;
Button calculate;
double x=0;
double y=0;
double z=0;
/** Called when the activity is first created. */
@Override

calculate.setOnClickListener(new Button.OnClickListener()

}
private void calculate()
{
x=Double.parseDouble(amount1.getText().toString());
y=Double.parseDouble(amount2.getText().toString());
z=x+y;
tt.setText(Double.toString(z));
// System.out.println("you are inside calculate");
}
}

and i have tried to use the numeric keyboard for the addition program and changed the code like this

Deepika,

As these buttons are already having an event. May be you could add some other buttons on the numeric keyboard for your required functionality. Because you can't expect the same button to behave in two different ways.

Probably you need to use a class to convert "A" into "அ" everytime a keypress event occured. Check out this Android Project's Utill Class

If you want to enter system wide then you gotta develop a IME for Android. There are many Tamil Android IME's such as Tamil Visai which is open source.

Does the font file exist under assets/fonts? How are you creating the Typeface object to create the font?

Instead of running the APK you find in the bin folder, run the whole project by loading it in Eclipse. It should work. I worte that code and its working fine in my SAmsung Ace.

It's happening due to some uncaught exception. Use an exception handler block (try..catch) to see what exception you are getting.

i have used an try catch exception like this but there is no variations in the result

for tamildemo

package com.mayuonline.tamildemo;

import android.app.Activity;
import android.graphics.Typeface;
import android.os.Bundle;
import android.widget.TextView;

public class TamilDemoActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try{
//initializing tf instance with Bamini font
Typeface tf = Typeface.createFromAsset(getAssets(),
"font/Bamini.ttf");

//Initializing TextView and setting the typeface created
TextView tamilTextView = (TextView)findViewById(R.id.textView1);
tamilTextView.setTypeface(tf);

//Tamil Unicode text goes here.
String tamilString = "வணக்கம் அன்ரொயிட்";

//creating intance of TamilFotnUtil Class
TamilFontUtil tfUtil = new TamilFontUtil();

//Convert Tamil font encording using the utility.
String tamilStringEncoded = tfUtil.convertTamilString(tamilString);

//Setting the text in the TextView
tamilTextView.setText(tamilStringEncoded);
}

catch(ArrayIndexOutOfBoundsException e){
//printed just to inform that we have entered the catch block
System.out.println("Oops, we went to far, better go back to 0!");
}

}
}
