Android TextView实现图文混排

TextView加载 不可否认有些抄的嫌疑 不够确实成功了

textView.setText(Html.fromHtml(html, imgGetter, null));
Html.ImageGetter imgGetter;

就这些解决了问题。

以前觉得图文混排会把图片给毁了，拉坏了，特别是用WebView掌握不好，就没谱了，现在终于解决了。哈哈哈！！！太高兴了。不说别的先复制粘贴代码，写好注释，感觉这样解决很简单。 等标签已经可以对文字和图片进行排版了

public class MainActivity extends AppCompatActivity {
    private TextView textView;
    private Html.ImageGetter imgGetter;
    private OkHttpClient httpOk;
    private String html=null;
//下边的就是Html的便签。
//    String html="斜体
"
//            +"

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
httpOk=new OkHttpClient();
textView=(TextView)findViewById(R.id.textView);
imgGetter=new Html.ImageGetter() {
@Override
public Drawable getDrawable(String source) {
//这里分割了 http://localhost:8080/img/ddd.jpg
String[] slipe=source.split("/");
String str=Environment.getExternalStorageDirectory().getAbsolutePath()+"/"+slipe[slipe.length-1];
//判断是否有这个图片
Drawable drawable=Drawable.createFromPath(str);
if(drawable!=null){
//如果有那么就返回图片
Log.i("tag","tag............"+"正确");
//别忘了设定图片的大小
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
return drawable;
}else {
//没有就下载图片
Log.i("tag", "tag............" + "错误");
new AsynTask().execute(slipe[slipe.length-1]);
}
return drawable;
}
};
//加这句才能让里面的超链接生效
textView.setMovementMethod(LinkMovementMethod.getInstance());

try {
//这是让Html重新加载的时候还有文字的缓存。
html=response.body().string();
textView.setText(Html.fromHtml(html, imgGetter, null));
