Display HTML Formatted String
I need an example of how to display the strings that I have marked up with simple html into a TextView. I have found "Spanned fromHtml(String source)", but I don't know how to plug it into my java code.
Here is my Java:
package com.SorenWinslow.TriumphHistory;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
public class TriumphHistory extends ListActivity {
String[] HistoryList;
/** Called when the activity is开发者_如何学Go first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ArrayAdapter<String> adapter;
HistoryList = getResources().getStringArray(R.array.history);
adapter = new ArrayAdapter<String> (this,R.layout.historylistlayout,HistoryList);
setListAdapter(adapter);
}
}
Here is a sample of history:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="history">
<item><b>1883</b><br/>Some stuff happened</item>
<item><b>1884</b><br/>Some more stuff happened <i>before</i> the other stuff
</item>
<resources>
Here is my historylistlayout.xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:textColor="#ffffff"
android:background="#000050"
android:layout_marginTop="5px"
android:minHeight="?android:attr/listPreferredItemHeight"
android:padding="3px"
android:textSize="8pt" android:layout_gravity="top|left"/>
And here is my main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:textColor="#ffffff"
android:background="#000080"
android:isScrollContainer="true"
android:layout_height="fill_parent"
android:layout_width="fill_parent" android:scrollbarStyle="insideOverlay">
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:dividerHeight="1px"/>
</LinearLayout>
I was trying to do something of the same nature and found out that my html along with CSS was not getting formatted correctly so I took the string and loaded it into a webview like this:
WebView webview = (WebView) findViewById(R.id.MyWebview);
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
webview.loadData(summary, "text/html", "utf-8");
and it recognized all the styles and formatted the html correctly. More from the android reference HERE
Use the function you mentioned to return a spanned and then set the text of your textview using the toString of the returned Spanned object like so to achieve formatted text:
Spanned marked_up = Html.fromHtml(yourTextWithHTML);
((TextView) findViewById(R.id.text1)).setText(marked_up.toString());
This will work where yourTextWithHTML is any of the Strings within the item tags you posted.
eg "<b>1883</b><br/>Some stuff happened"
Spanned spannedContent = Html.fromHtml(htmlString);
textView.setText(spannedContent, BufferType.SPANNABLE);
This seems easiest actually (from HTML in string resource?):
mTextView.setText(getText(R.string.my_styled_text));
This works for strings that have HTML inside.
I faced the same problem, and solved it by using
CharSequence[] HistoryList = getResources().getTextArray(R.array.history);
The above code returns styled text array associated with resource. It will return CharSequence[]
Then just use the elemens in
setText(HistoryList[index]);
