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 class="lazy" data-src='image1'/>";    html+="<font>图片2</font><img class="lazy" data-src='image2'/>";    html+="<font>图片3</font><img class="lazy" data-src='image3'/>";    html+="<font>图片4</font><img class="lazy" data-src='image4'/>";    html+="<font>图片5</font><img class="lazy" data-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);      }    private int getDrawableResurceID(String imageName){    //利用反射机制取得图片的id        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;      }}
