Code for reading from a text file in asset folder to a textview:

public class Readfile extends Activity {
    String path;
    ArrayList data = new ArrayList();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        path = getResources().getString(R.string.directory1);
        String[] data1 = null;
        AssetManager am = getResources().getAssets();
        try {
            data1 = am.list(path);
        } catch (Exception e) {
        }
        for (String name : data1) {
            data.add(name);
        }
        Readoperation();
    }
    public void Readoperation() {
        // TODO Auto-generated method stub
        TextView txt = (TextView) findViewById(R.id.text);
        try {  
            path=getResources().getString(R.string.directory1) +"/"+data.get(2);
            InputStream stream = getAssets().open(path);
            int size = stream.available();
            byte[] buffer = new byte[size];
            stream.read(buffer);
            stream.close();
            txt.setText(Html.fromHtml(new String(buffer).trim()));
            }
           catch (IOException e) {
        }}
