Android doesn't support various fonts like Marathi so this tutorial gives you idea about how to use various font like Marathi in your app.So you can display your data in various languages using the font combination in your app.

Step1)First you have to download the .ttf file like (akshar.ttf for marathi font) which will be used for converting your text according to this font.

           b)  Typeface tf = Typeface.createFromAsset(getAssets(), "akshar.ttf");
                  t1.setTypeface(tf, Typeface.BOLD);

                  <TextView
                    android:id="@+id/t1"
                   android:layout_width="fill_parent"
                   android:layout_height="fill_parent"
                   android:text="@string/sindhu"
                   android:textColor="#000000"
                   android:textSize="6pt" />

Code To Start Camera with Build-in Intent

This code will show you how to start camera using intent and save the image to the file name.

Step1)Private constants & variable uses in the class:

 private static int TAKE_PIC = 1;
 private Uri FileUri;

Step2)Once the code is run, the camera pops up, just take your photo, and click on “Done” button on the screen. That would close the camera app and returns to your own App.
          

  private void ClickPhoto() {
  Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  File file = new File(Environment.getExternalStorageDirectory(), "img1.jpg");
 
  FileUri = Uri.fromFile(file);
  intent.putExtra(MediaStore.EXTRA_OUTPUT, FileUri);
  startActivityForResult(intent, TAKE_PICTURE);
 

}

Step3)You need to override the onActivityResult to handle when the camera returns to your app:
                         

 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data){
 
  if (requestCode == TAKE_PIC){
   //do whatever you want
  }
 
 }

Creating a dynamic row in TableLayout..

All of you know to add a no.of rows in Table-layout by using XML.but here i will provide you the
guideline for generating rows dynamically in your android code.


Step:1)First of all you add Table-layout in your XML file.like following

         <TableLayout

                       android:id="@+id/tbl_product"

                       android:layout_width="fill_parent"

                      android:layout_height="wrap_content" >

        </TableLayout>

Step:2)Then u add the follwing code in your java file.


A) First,you set up the control for table layout.

         TableLayout prodlist = (Table Layout) findViewById(R.id.tbl_product);


B) Second,you will create a method name display(). in that u create a row using follwing:

        void display(String id, String name) {

        Table Row tr2 = new Table Row(this);

        tr2.layout(0, 0, 0, 0);

C) Third,you will create a two text view which will be added in that above row and set the argument value of display() method to that text view.


First text-view:


      TextView lblid = new TextView(this);

        lblid.setText("" + id);

        lblid.setTextColor(Color.BLACK);

        lblid.setTextSize((float) 11.5);

        lblid.setTypeface(null, 1);

        lblid.setBackgroundColor(Color.TRANSPARENT);

        lblid.setPadding(30, 0, 0, 0);

        tr2.setPadding(0, 1, 0, 0);

        tr2.addView(lblid);

Second text-view:


      TextView lblname = new TextView(this);

        lblname.setText("" + name);

        lblname.setTextColor(Color.BLACK);

        lblname.setTextSize((float) 11.5);

        lblname.setTypeface(null, 1);

        lblname.setBackgroundColor(Color.TRANSPARENT);

        lblname.setPadding(30, 0, 20, 0);

        tr2.setPadding(0, 1, 0, 1);

        tr2.addView(lblname);

 

Step:3)

Next most important thing is add the table row to the tableLayout by the following:


       prodlist.addView(tr2, new TableLayout.LayoutParams(

                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
