TextView实现图文混合编排的方法

package fry;

import java.lang.reflect.Field;

import com.example.textViewDemo1.R;

import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.text.Html;
import android.text.Html.ImageGetter;
import android.widget.TextView;

public class ActivityDemo2 extends Activity{
  private TextView tv_textAndImage;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity02);
    setTitle("TextViewDemo2");
    tv_textAndImage=(TextView) findViewById(R.id.tv_textAndImage);
    //第一步，设置文本
    String html="<font>图片1</font><img src='image1'/>";
    html+="<font>图片2</font><img src='image2'/>";
    html+="<font>图片3</font><img src='image3'/>";
    html+="<font>图片4</font><img src='image4'/>";
    html+="<font>图片5</font><img src='image5'/>";
    //第二步，告诉TextView控件这是html，并且获取文本中的图片源
    CharSequence text=Html.fromHtml(html, new ImageGetter() {
      
      public Drawable getDrawable(String source) {
        // TODO Auto-generated method stub
        //根据图片资源ID获取图片
        //getResources就是去找项目里面的res文件夹
        Drawable drawable=getResources().getDrawable(getDrawableResurceID(source));
        //一定要加上边界这部分代码。要不然drawable会因为信息不完整读不出来图片
        //分别是left top width height 
        drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
        return drawable;
      }
    }, null);
    //第三步、将CharSequence字符串序列的文本text插入到TextView控件中即可
    tv_textAndImage.setText(text);
    
  }
  /**
   * 获取图片的资源ID
   * @param imageName 图片的名称
   * @return 图片对应的ID
   * 
   */
  private int getDrawableResurceID(String imageName){
    //利用反射机制取得图片的id
    /*
     * 其实是找com.example.textViewDemo1.R.drawable.image1的值，也就是
     * public static final int image1=0x7f020001;
     * 也就是0x7f020001
     * 例如image1，返回的就是0x7f020001
     */
    try {
      Field field=R.drawable.class.getField(imageName);
      return Integer.parseInt(field.get(null).toString()); 
    } catch (Exception e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
    
    return 0;
    
  }
}
