How do I put an external source in my app?

Question

I’m trying to put a custom font in my app, but I’m having too many mistakes.

I’ve tried using Pixlui, I’ve tried several different codes and always error, or the application runs, but crash (app Stopped).

This is the code I’m trying to put inside the Mainactivity.java:

TextView tx = (TextView)findViewById(R.id.textView1);
Typeface custom_font = Typeface.createFromAsset(this.getAssets(),
    "fonts/watermelon.ttf");
tx.setTypeface(custom_font);

This is the code of Mainactivity:

@SuppressWarnings("unused")
public class MainActivity extends ActionBarActivity{


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    TextView tx = (TextView)findViewById(R.id.textView1);
    Typeface custom_font = Typeface.createFromAsset(this.getAssets(),
    "fonts/watermelon.ttf");
    tx.setTypeface(custom_font);                
    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment())
                .commit();}
                }

public void opensecondactivity(View view) {
    Intent intent = new Intent(this , SecondActivity.class);
    startActivity(intent);
    overridePendingTransition(R.anim.slide_in, R.anim.slide_out);
       } 

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    Intent intent = new Intent(this , AboutActivity.class);
    startActivity(intent);
    overridePendingTransition(R.anim.slide_in, R.anim.slide_out);
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

/**
 * A placeholder fragment containing a simple view.
 */
public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {
          }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
                View rootView = inflater.inflate(R.layout.fragment_main, container, false);
                return rootView;               
            }
     }
}

With this code Eclipse declares no error, but when it executes the Activity it error and the application is closed alone. What to do?

Just for the record, the font is in the "Assets/fonts folder"

EDIT - SOLUTION: Thanks to everyone who helped me! The solution was to implement the code within the public View onCreateView. Look how it turned out:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main, container, false);

        TextView txt = (TextView) rootView.findViewById(R.id.TextView1);
        Typeface font = Typeface.createFromAsset(getActivity().getAssets(), "fonts/laouib.TTF");
        txt.setTypeface(font); 

        return rootView; 

Answer 1

To read external fonts, I put the fonts in the root of the Asset folder and created a "Fontchanger" class that only has methods for changing fonts. All methods are static so you don’t need to instantiate the class. The only thing I pass to the method is Context. Implementation of the method within the Fontchanger class :

public static Typeface setRobotoRegular(Context context)
{
     return Typeface.createFromAsset(context.getAssets(),"roboto_regular.ttf");
}

changing the source of a textView you have in my application:

meuTextView.setTypeFace(FontChanger.setRobotoRegular(context));

Answer 2

Right-click the folder "res" > New>Android Resource Diretory. Put a name of your preference in the directory and in "Resource type" select the type "font" and press ok. After that just copy your fonts into the created folder.

Note: Before copying the fonts, rename and remove all the special characters and strokes, because Android Studio does not accept files with names like this.

Example: DS-DIGITAL.TFF >>>>>> dsdigital.tff!
