我怎樣才能爲我的WebView創建paging，從Epub填充。如何在我的epub頁面中創建分頁？ android
我MainActivity.java：
public class MainActivity extends ActionBarActivity implements OnClickListener {
WebView webView;
Handler hand;
String data = null;
LinearLayout books;
int pagecount = 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);
books = (LinearLayout) findViewById(R.id.book);
AssetManager assetManager = getAssets();
try {
InputStream epubInputStream = assetManager.open("mybook.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();
Button btnnext = (Button) findViewById(R.id.btnNext);
Button btnPreviuse = (Button) findViewById(R.id.btnPreviuse);
btnnext.setOnClickListener(this);
btnPreviuse.setOnClickListener(this);
} catch (IOException e) {
Log.e("Log_four", e.getMessage());
}
}
private void logTableOfContents(List<TOCReference> tocReferences, int depth) {
if (tocReferences == null) {
return;
}
for (TOCReference tocReference : tocReferences) {
StringBuilder tocString = new StringBuilder();
for (int i = 0; i < depth; i++) {
tocString.append("\t");
}
tocString.append(tocReference.getTitle());
Log.i("Log_five", tocString.toString());
logTableOfContents(tocReference.getChildren(), depth + 1);
}
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.btnNext) {
try {
int i = pagecount + 7;
webView = new WebView(this);
books = (LinearLayout) findViewById(R.id.book);
data = new String(book.getContents().get(i).getData());
webView.loadDataWithBaseURL("file:///android_asset/", data, "text/html", "UTF-8", null);
books.addView(webView);
} catch (IOException e) {
e.printStackTrace();
}
} else if (v.getId() == R.id.btnPreviuse) {
try {
int i = pagecount - 1;
webView = new WebView(this);
books = (LinearLayout) findViewById(R.id.book);
data = new String(book.getContents().get(i).getData());
webView.loadDataWithBaseURL("file:///android_asset/", data, "text/html", "UTF-8", null);
books.addView(webView);
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
當我click的按鈕，我需要看到另一個page但我看不到。 我activity_main.xml：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/book"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="@+id/Footer"
android:layout_width="match_parent"
android:layout_height="100dip"
android:layout_weight="1"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<Button
android:id="@+id/btnNext"
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight="0.5"
android:text="Next Page" />
<Button
android:id="@+id/btnPreviuse"
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight="0.5"
android:text="Previuse Page" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
