推荐答案

您可以使用这段代码，其中 mPath 是保存文件的路径， mMainView 是要捕获的视图.

You can use this code, where mPath is path to save file, and mMainView is view to capture.

如果要更改文件类型或压缩率，请修改以下代码.

If you want to change file type or compress rate, modify below code.

bitmap.compress(Bitmap.CompressFormat.PNG, 90, fout);

bitmap.compress(Bitmap.CompressFormat.PNG, 90, fout);

private void captureScreen() {

    String mPath = getAppStorageFolder(getActivity()) + File.separator + "test.png";

    // create bitmap screen capture
    Bitmap bitmap;
    View v1 = webView.getRootView();
    v1.setDrawingCacheEnabled(true);
    bitmap = Bitmap.createBitmap(v1.getDrawingCache());
    v1.setDrawingCacheEnabled(false);

    OutputStream fout = null;
    File imageFile = new File(mPath);

    try {
        fout = new FileOutputStream(imageFile);
        bitmap.compress(Bitmap.CompressFormat.PNG, 90, fout);
        fout.flush();
        fout.close();

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

public String getAppStorageFolder(Activity activity) {
    return Environment.getExternalStorageDirectory() + File.separator + activity.getString(R.string.app_name);
}
