本文介绍了一种在Android设备上进行屏幕截图的方法，并提供了将截图保存为JPEG或PNG格式的具体实现。此外，还提供了获取屏幕截图的其他几种方式供参考。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

private void printScreen(boolean save) {//截屏 View view = this.getWindow().getDecorView();//this是当前的Activity // if (view.isDrawingCacheEnabled()) { view.setDrawingCacheEnabled(true); Calendar c = Calendar.getInstance(); String date = c.get(Calendar.YEAR) + "-" + (c.get(Calendar.MONTH) + 1) + "-" + c.get(Calendar.DAY_OF_MONTH) + " " + c.get(Calendar.HOUR_OF_DAY) + "-" + c.get(Calendar.MINUTE) + "-" + c.get(Calendar.SECOND); // } view.buildDrawingCache(); Bitmap bmp = view.getDrawingCache(); imagePath = ConstValue.MY_ALBUM_DIR + "/" + date + ".jpg";//路径 writePhotoJpg(bmp, imagePath); // FileSaveAsync myAsync = new FileSaveAsync(bmp, imagePath, true); // myAsync.execute(); }

保存到sd卡下的方法：（记得加上写入sd卡的权限）

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" ></uses-permission>

public void writePhotoJpg(Bitmap data, String pathName) { File file = new File(pathName); try { file.createNewFile(); // BufferedOutputStream os = new BufferedOutputStream( // new FileOutputStream(file)); FileOutputStream os = new FileOutputStream(file); data.compress(Bitmap.CompressFormat.JPEG, 100, os); os.flush(); os.close(); MyDebug.i("writePhotoJpg"); } catch (Exception e) { e.printStackTrace(); } } public void writePhotoPng(Bitmap data, String pathName) { File file = new File(pathName); try { file.createNewFile(); FileOutputStream os = new FileOutputStream(file); // BufferedOutputStream os = new BufferedOutputStream( // new FileOutputStream(file)); data.compress(Bitmap.CompressFormat.PNG, 100, os); os.flush(); os.close(); MyDebug.i("writePhotoPng"); } catch (Exception e) { e.printStackTrace(); } }

另外几种方法，没仔细测试过：仅供参考

//抓屏的方式生成照片 public static Bitmap printScreen(Context context) { View view = ((Activity) context).getWindow().getDecorView(); // if (view.isDrawingCacheEnabled()) { view.setDrawingCacheEnabled(true); // Calendar c = Calendar.getInstance(); // String date = c.get(Calendar.YEAR) + "-" + (c.get(Calendar.MONTH) + 1) + "-" + c.get(Calendar.DAY_OF_MONTH) + " " + c.get(Calendar.HOUR_OF_DAY) + "-" + c.get(Calendar.MINUTE) + "-" + c.get(Calendar.SECOND); // } view.buildDrawingCache(); Bitmap bmp = view.getDrawingCache(); return bmp; /*imagePath = ConstValue.MY_ALBUM_DIR + "/" + date + ".jpg"; ImageFile.writePhotoJpg(bmp, imagePath);*/ // FileSaveAsync myAsync = new FileSaveAsync(bmp, imagePath, true); // myAsync.execute(); } public static Bitmap catchScreen(View v1) { v1.setDrawingCacheEnabled(true); Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache()); v1.setDrawingCacheEnabled(false); return bitmap; }
