Android 各种截屏方法

概述1应用内截屏(无SurfaceView,TextureView)booleancacheEnable=captureView.isDrawingCacheEnabled();captureView.setDrawingCacheEnabled(true);captureView.buildDrawingCache();Bitmapbitmap=captureView.getDrawingCache();cache[0]=Bitmap.createBitmap(

1 应用内截屏(无SurfaceVIEw, TextureVIEw)

boolean cacheEnable = captureVIEw.isDrawingCacheEnabled();captureVIEw.setDrawingCacheEnabled(true);captureVIEw.buildDrawingCache();Bitmap bitmap = captureVIEw.getDrawingCache();cache[0] = Bitmap.createBitmap(bitmap);captureVIEw.setDrawingCacheEnabled(cacheEnable);

2 应用内截屏.需要权限androID.permission.READ_FRAME_BUFFER

display display = ((WindowManager)captureVIEw.getContext()     .getSystemService(Context.WINDOW_SERVICE)).getDefaultdisplay();displayMetrics displayMetrics = new displayMetrics();display.getRealMetrics(displayMetrics);Bitmap bitmap = SurfaceControl.screenshot(displayMetrics.wIDthPixels,     displayMetrics.heightPixels);

3 AndroID 9.0

        Pixelcopy.request(window, bitmap, new Pixelcopy.OnPixelcopyFinishedListener() {        @OverrIDe        public voID onPixelcopyFinished(int copyResult){            if (Pixelcopy.SUCCESS == copyResult) {                // onSuccessCallback(bitmap)            } else {                // one rrorCallback()            }        }    }, new Handler());

4 读 framebuffer

        String DEVICE_name = "/dev/graphics/fb0";        file devicefile = new file(DEVICE_name);        Process localProcess = Runtime.getRuntime().exec("supersu");        String str = "cat " + devicefile.getabsolutePath() + "\n";        localProcess.getoutputStream().write(str.getBytes());        return localProcess.getinputStream();

5 拼接TextureVIEw (Todo)
