1、Activity

case TAKE_PHOTO:if (arg2 != null) {Bitmap one = null;Uri photoUri = arg2.getData(); Bundle extra = arg2.getExtras();          if (extra != null) {          one = (Bitmap)extra.get("data");        }    iv3.setImageBitmap(one);    SecureRandom random = new SecureRandom();      String picPath = Util.saveBitmap(""+random.nextInt(10000), one);            semdrommessage(picPath.trim(), Content.DaTingSERVICE_Home+ "@conference." + Content.DaTingSERVICE_Name);}break;

2、工具，保存图片到地址

public static String saveBitmap(String name, Bitmap bitmap) {File oneFile = new File(Content.APP_PATH + File.separator + name+ ".png");if (oneFile.exists())oneFile.delete();try {oneFile.createNewFile();FileOutputStream stream = new FileOutputStream(oneFile);bitmap.compress(CompressFormat.JPEG, 100, stream);stream.flush();stream.close();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return oneFile.toString();}

3、Adapter

if (entity.getText().contains(".png")) {viewHolder.tvContent.setText("");ImageSpan imageSpan = new ImageSpan(ctx,Util.getDiskBitmap(entity.getText()));             SpannableString spannableStringTuPian = new SpannableString("pp");   //这个pp不能删，必须有任意字符串，否则报错            spannableStringTuPian.setSpan(imageSpan, 0, spannableStringTuPian.length(),                      Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);             viewHolder.tvContent.setText(spannableStringTuPian);} else {viewHolder.tvContent.setText(spannableString);}

4、转本地为Bitmap

if (entity.getText().contains(".png")) {viewHolder.tvContent.setText("");ImageSpan imageSpan = new ImageSpan(ctx,Util.getDiskBitmap(entity.getText()));             SpannableString spannableStringTuPian = new SpannableString("pp");             spannableStringTuPian.setSpan(imageSpan, 0, spannableStringTuPian.length(),                      Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);             viewHolder.tvContent.setText(spannableStringTuPian);} else {viewHolder.tvContent.setText(spannableString);}
