In my application I need to set dynamic text to my textview so I want it to get resized dynamically. I have set:
As Konstantin said, this code will probably be ignored after you exceed 4 lines unless you remove android:maxLines="4"
This is how you would set the height in code:
TextView tv = (TextView) findViewById(R.id.TextView02);
int height_in_pixels = tv.getLineCount() * tv.getLineHeight(); //approx height text
tv.setHeight(height_in_pixels);
If you want to use dip units, which allows your app to scale across multiple screen sizes, you would multiply the pixel count by the value returned by getResources().getDisplayMetrics().density;
This depends on your desired behavior, but you might also consider having the TextView size fixed, and allowing the user to scroll the text:
TextView tv = (TextView)findViewById(R.id.TextView02);
tv.setMovementMethod(ScrollingMovementMethod.getInstance());
TextView tv;
----------------------
tv=new TextView(this); // you take TextView id (R.id.textview1)
LinearLayout.LayoutParams Params1 = new LinearLayout.LayoutParams(15,50);
tv.setLayoutParams(Params1); //you take linearlayout and relativelayout.
Remove android:maxLines="4", it restricts height of your view to 4 lines of text.
