这是我的代码
btnSave.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT) {
createWebPrintJob(webView);
}else {
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
Picture picture = view.capturePicture();
Bitmap b = Bitmap.createBitmap(
picture.getWidth(), picture.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
picture.draw(c);
FileOutputStream fos = null;
try {
fos = new FileOutputStream( "/sdcard/" + "page.jpg" );
if ( fos != null ) {
b.compress(Bitmap.CompressFormat.JPEG, 90, fos );
fos.close();
}
}
catch( Exception e ) {
System.out.println("-----error--"+e);
}
}
});
Toast.makeText(WebViewActivity.this, "Saved", Toast.LENGTH_SHORT).show();
}
}
});
如果用户sdk> kitkat然后webview被视为pdf并且如果用户sdk
保存pdf的一部分工作成功,但保存图像不起作用 请帮帮我,我需要这个选项。

我在我的一个项目中使用过这段代码。这很好用。试一试。
webView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
// do your stuff here
webView.measure(MeasureSpec.makeMeasureSpec(
MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
webView.layout(0, 0, webView.getMeasuredWidth(),
webView.getMeasuredHeight());
webView.setDrawingCacheEnabled(true);
webView.buildDrawingCache();
Bitmap bm = Bitmap.createBitmap(webView.getMeasuredWidth(),
webView.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas bigcanvas = new Canvas(bm);
Paint paint = new Paint();
int iHeight = bm.getHeight();
bigcanvas.drawBitmap(bm, 0, iHeight, paint);
webView.draw(bigcanvas);
System.out.println("WIDTH"
+ bigcanvas.getWidth());
System.out.println("HEIGHT="
+ bigcanvas.getHeight());
if (bm != null) {
try {
String path = Environment.getExternalStorageDirectory()
.toString();
OutputStream fOut = null;
File file = new File(path, "/aaaa.png");
fOut = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.PNG, 50, fOut);
fOut.flush();
fOut.close();
bm.recycle();
} catch (Exception e) {
e.printStackTrace();
}
}
}
});
答案 1 :(得分:-1)
webView.setDrawingCacheEnabled(true);
在onPageFinished()
Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache());
imageView.setImageBitmap(bitmap);
希望这会有所帮助......
