是否有可能为此应用配置自定义字体TextView？

Question

Using Android Studio 1.3 - and based on an online tutorial - I run this app successfully on my android phone, as it is, but I have unsuccessfully tried more than half a dozen different ListView and TextView configurations, some from this excellent stackoverflow site, in order to try to get a custom font to display the text within the .xml. Although I'm using a rooted Android 4.3 to debug and run, I would need to eventually modify and distribute this particular app with a custom font because oem fonts on rooted and unrooted phones and devices lack the repertoire of the local language's characters. I've made the fonts already from Google open source fonts. Using only the MainActivity.java and the row_site.xml below, is it possible for me to modify the textView to use the custom font that it appears I would place within and distribute from the /assets/fonts folder or would it be helpful if I include other files from this project?

MainActivity

package com.example.stacksites;

import java.io.FileNotFoundException;

public class MainActivity extends Activity {

    private SitesAdapter mAdapter;
    private ListView sitesList;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.i("StackSites", "OnCreate()");
        setContentView(R.layout.activity_main);

        //Get reference to our ListView
        sitesList = (ListView)findViewById(R.id.sitesList);

        //Set the click listener to launch the browser when a row is clicked.
        sitesList.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View v, int pos,long id) {
                String url = mAdapter.getItem(pos).getLink();
                Intent i = new Intent(Intent.ACTION_VIEW);
                i.setData(Uri.parse(url));
                startActivity(i);

            }

        });

        /*

         * If not then try to use the local file from last time.
         */
        if(isNetworkAvailable()){
            Log.i("StackSites", "starting download Task");
            SitesDownloadTask download = new SitesDownloadTask();
            download.execute();
        }else{
            mAdapter = new SitesAdapter(getApplicationContext(), -1, SitesXmlPullParser.getStackSitesFromFile(MainActivity.this));
            sitesList.setAdapter(mAdapter);

    }

              = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        return activeNetworkInfo != null && activeNetworkInfo.isConnected();
    } 

    /*

        @Override
        protected Void doInBackground(Void... arg0) {
            //Download the file
            try {
                Downloader.DownloadFromUrl("http://example.com/stacksites.xml", openFileOutput("StackSites.xml", Context.MODE_PRIVATE));
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }

            return null;
        }

        @Override
        protected void onPostExecute(Void result){
            //setup our Adapter and set it to the ListView.
            mAdapter = new SitesAdapter(MainActivity.this, -1, SitesXmlPullParser.getStackSitesFromFile(MainActivity.this));
            sitesList.setAdapter(mAdapter);
            Log.i("StackSites", "adapter size = "+ mAdapter.getCount());
        }
    }

}

Answer 1

You can put your custom font into assets then try using Typeface.createFromAsset()

Then TextView.setTypeface() passing the created typeface
