我尝试在 Html.fromHtml() 中显示文本和图像，但它在图像显示中不起作用。
message = (TextView) findViewById (R.id.message);
message.setText(Html.fromHtml(
"<p><b>First, </b><br/>" +
"Please press the" + "<img src = 'addbutton.png' />" + " to insert a new event.</p>"));
文字显示正常，图片显示不出来。如何改进？

这是供用户引用的编码pskink ...
package com.tutorial.myjob;
import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.LevelListDrawable;
import android.os.Bundle;
import android.text.*;
import android.text.Html.ImageGetter;
import android.widget.*;
public class HelpMenu extends Activity implements ImageGetter{
TextView message;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.help_menu);
String code = "<p><b>First, </b><br/>" +
"Please press the <img src ='addbutton.png'> button beside the to insert a new event.</p>" +
"<p><b>Second,</b><br/>" +
"Please insert the details of the event.</p>"
"<p>The icon of the is show the level of the event.<br/>" +
"eg: <img src = 'tu1.png' > is easier to do.</p></td>";
message = (TextView) findViewById (R.id.message);
Spanned spanned = Html.fromHtml(code, this, null);
message.setText(spanned);
message.setTextSize(16);
}
@Override
public Drawable getDrawable(String arg0) {
// TODO Auto-generated method stub
int id = 0;
if(arg0.equals("addbutton.png")){
id = R.drawable.addbutton;
}
if(arg0.equals("tu1.png")){
id = R.drawable.tu1;
}
LevelListDrawable d = new LevelListDrawable();
Drawable empty = getResources().getDrawable(id);
d.addLevel(0, 0, empty);
d.setBounds(0, 0, empty.getIntrinsicWidth(), empty.getIntrinsicHeight());
return d;
}
}
这是我编辑的...这些代码对我来说运行良好...非常感谢那些帮助我的人...感谢~ ^^
