问题描述

我会知道什么是code取当前屏幕的截图(后一个按钮,preSS)并将其保存在一个画廊,因为我没有使用SD卡的设备。所以我会保存在默认画廊。谢谢

解决方案

 点阵位图;
  查看V1 = findViewById(R.id.rlid); //获取乌尔根视图id
  v1.setDrawingCacheEnabled(真正的);
  位图= Bitmap.createBitmap(v1.getDrawingCache());
  v1.setDrawingCacheEnabled(假);
 

这应该做的伎俩。

有关节能

  ByteArrayOutputStream字节=新ByteArrayOutputStream();
  bitmap.com preSS(Bitmap.Com pressFormat.JPEG,40个字节);
  文件F =新的文件(Environment.getExternalStorageDirectory()
                    +文件分割符+test.jpg放在)
  f.createNewFile();
  FileOutputStream中FO =新的FileOutputStream(F);
  fo.write(bytes.toByteArray());
  fo.close();
 

i would to know what is the code to take a screenshot of the current screen (after a press of a button) and save it on a gallery because I don't have a device with sd cards. So i would to save in the default gallery. thank you

解决方案
  Bitmap bitmap;
  View v1 = findViewById(R.id.rlid);// get ur root view id
  v1.setDrawingCacheEnabled(true);
  bitmap = Bitmap.createBitmap(v1.getDrawingCache());
  v1.setDrawingCacheEnabled(false);

This should do the trick.

For saving

  ByteArrayOutputStream bytes = new ByteArrayOutputStream();
  bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
  File f = new File(Environment.getExternalStorageDirectory()
                    + File.separator + "test.jpg")
  f.createNewFile();
  FileOutputStream fo = new FileOutputStream(f);
  fo.write(bytes.toByteArray());
  fo.close();
