java - 在 android 中捕获完整的 webView

Question

我无法捕获完整的 WebView，我只捕获 Dashboard(Activity) 的可见内容。我的 WebView 超出了 Activity 范围。指导我如何捕获完整 View 。

webView.setWebViewClient(new WebViewClient() {

    public void onPageFinished(WebView v, String url) {
        webView.setDrawingCacheEnabled(true);
        webView.buildDrawingCache();
        Bitmap bmp = Bitmap.createBitmap(webView.getWidth(), webView.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bmp);
        webView.draw(canvas);
        imgView.setImageBitmap(bmp);
    }
});

Answer 1

webView.setWebViewClient(new WebViewClient() {

    public void onPageFinished(WebView v, String url) {
        Picture picture = v.capturePicture();
        Bitmap bmp = Bitmap.createBitmap(
                      picture.getWidth(), picture.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(b);
        picture.draw(canvas);
        imgView.setImageBitmap(bmp);      
}

对不起，我没注意到

This method was deprecated in API level 19. Use onDraw(Canvas) to obtain a bitmap snapshot of the WebView, or saveWebArchive(String) to save the content to a file.

Gets a new picture that captures the current contents of this WebView. The picture is of the entire document being displayed, and is not limited to the area currently displayed by this WebView. Also, the picture is a static copy and is unaffected by later changes to the content being displayed.
