不多说废话，直接上代码
屏幕截图，亲测可用，基于Activity
/*** 屏幕截图* @param activity* @return*/public static Bitmap screenShot(AppCompatActivity activity,String filePath) {if (activity == null){Logger.getLogger().e("screenShot--->activity is null");return null;}View view = activity.getWindow().getDecorView();//允许当前窗口保存缓存信息view.setDrawingCacheEnabled(true);view.buildDrawingCache();int navigationBarHeight = ScreenUtils.getNavigationBarHeight(view.getContext());//获取屏幕宽和高int width = ScreenUtils.getScreenWidth(view.getContext());int height = ScreenUtils.getScreenHeight(view.getContext());// 全屏不用考虑状态栏，有导航栏需要加上导航栏高度Bitmap bitmap = null;try {bitmap = Bitmap.createBitmap(view.getDrawingCache(), 0, 0, width,height + navigationBarHeight);} catch (Exception e) {// 这里主要是为了兼容异形屏做的处理，我这里的处理比较仓促，直接靠捕获异常处理// 其实vivo oppo等这些异形屏手机官网都有判断方法// 正确的做法应该是判断当前手机是否是异形屏，如果是就用下面的代码创建bitmapString msg = e.getMessage();// 部分手机导航栏高度不占窗口高度，不用添加，比如OppoR15这种异形屏if (msg.contains("<= bitmap.height()")){try {bitmap = Bitmap.createBitmap(view.getDrawingCache(), 0, 0, width,height);} catch (Exception e1) {msg = e1.getMessage();// 适配Vivo X21异形屏，状态栏和导航栏都没有填充if (msg.contains("<= bitmap.height()")) {try {bitmap = Bitmap.createBitmap(view.getDrawingCache(), 0, 0, width,height - ScreenUtils.getStatusHeight(view.getContext()));} catch (Exception e2) {e2.printStackTrace();}}else {e1.printStackTrace();}}}else {e.printStackTrace();}}//销毁缓存信息view.destroyDrawingCache();view.setDrawingCacheEnabled(false);if (null != bitmap){try {compressAndGenImage(bitmap,filePath);Logger.getLogger().d("--->截图保存地址：" + filePath);} catch (IOException e) {e.printStackTrace();}}return bitmap;}
View截图，亲测可用 参考
/*** view截图* @return*/public static void viewShot(@NonNull final View v, @Nullable final String filePath,@Nullable final ShotCallback shotCallback){if (null == v) {Logger.getLogger().e("view is null");return;}v.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {@Overridepublic void onGlobalLayout() {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {v.getViewTreeObserver().removeOnGlobalLayoutListener(this);} else {v.getViewTreeObserver().removeGlobalOnLayoutListener(this);}// 核心代码startBitmap bitmap = Bitmap.createBitmap(v.getWidth() , v.getHeight(), Bitmap.Config.ARGB_8888);Canvas c = new Canvas(bitmap);v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height);v.draw(c);// endString savePath = filePath;if (TextUtils.isEmpty(savePath)){savePath = createImagePath();}try {compressAndGenImage(bitmap,savePath);Logger.getLogger().d("--->截图保存地址：" + savePath);} catch (IOException e) {e.printStackTrace();}if (null != shotCallback){shotCallback.onShotComplete(bitmap,savePath);}}});}
关于View截图，如果需要实现后台截图，也就是截图的时候view不在屏幕显示显示，只需要把要截图的View设置成invisible就可以了。 另外再附上生成图片和保存到手机SD卡上的方法，一步到位，直接粘贴拿去就用。
