我想将视图渲染到位图并保存位图。但我需要在屏幕外完成这一切。

我试过这个：

Canvas c = new Canvas(bm);
linearview.layout(0, 0, linearview.getLayoutParams().width, linearview.getLayoutParams().height);
linearview.draw(c);

    extStorageDirectory = Environment.getExternalStorageDirectory().toString();
    OutputStream outStream = null;
    File file = new File(extStorageDirectory, "screen1.PNG");

    try {
        outStream = new FileOutputStream(file);
        bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
        outStream.flush();
        outStream.close();


    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch …
