Question

是否可以在android中为FontSize设置epub boooks可用性？

注意：我在epub显示WebView的数据。

我需要为集FontSize创建一个选项。

public class MainActivity extends ActionBarActivity implements OnClickListener{
    WebView webView;
    Handler hand ;
    String data = null;
    LinearLayout books;
    int pagecount = 1;
    int y = 1;
    Book book;
    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        hand = new Handler();
        webView = new WebView(this);
        webView.getSettings().setJavaScriptEnabled(true);
        books = (LinearLayout) findViewById(R.id.book);
         AssetManager assetManager = getAssets();
         try{
             InputStream epubInputStream = assetManager.open("ok.epub");
             book = (new EpubReader()).readEpub(epubInputStream);
             Log.i("Log_one", "author(s): " + book.getMetadata().getAuthors());
             Log.i("Log_two", "title: " + book.getTitle());
             Bitmap coverImage = BitmapFactory.decodeStream(book.getCoverImage().getInputStream());
             Log.i("Log_three", "Coverimage is " + coverImage.getWidth() + " by " + coverImage.getHeight() + " pixels");
             logTableOfContents(book.getTableOfContents().getTocReferences(), 0);

             Spine spine = book.getSpine(); 
             List<SpineReference> spineList = spine.getSpineReferences() ;
             int count = spineList.size();

             String datas = new String(book.getContents().get(1).getData());
             webView.loadDataWithBaseURL("file:///android_asset/", datas, "text/html", "UTF-8", null);
             books.addView(webView);
             Log.i("Log_four", datas);

         }
         catch (IOException e) {
              Log.e("Log_four", e.getMessage());
            }

         webView.setOnTouchListener(new OnSwipeTouchListener(G.context){
                public void onSwipeTop() {
                    Toast.makeText(MainActivity.this, "top", Toast.LENGTH_SHORT).show();
                }
                public void onSwipeRight() {    
                    try {

                        books.removeAllViews();
                        int i = pagecount + y;
                        y = i;
                            books = (LinearLayout) findViewById(R.id.book);

你可以设置android webview的字体大小。

WebSettings webSettings = webView.getSettings();

setTextSize或

webSettings.setTextSize(WebSettings.TextSize.SMALLEST);

这个也适用： -

webSettings.setDefaultFontSize(10);

由于

android中epubs的字体大小？
