使用以下代碼：Bitmap?bitmap;View?v1?=?MyView.getRootView();v1.setDrawingCacheEnabled(true);bitmap?=?Bitmap.createBitmap(v1.getDrawingCache());v1.setDrawingCacheEnabled(false);

這MyView是View我們需要在屏幕中包含的內容。你也可以DrawingCache通過View這種方式獲得(沒有getRootView())。

還有另一種方式..

如果我們ScrollView以root身份查看，那么最好使用以下代碼，LayoutInflater?inflater?=?(LayoutInflater)?this.getSystemService(LAYOUT_INFLATER_SERVICE);FrameLayout?root?=?(FrameLayout)?inflater.inflate(R.layout.activity_main,?null);?//?activity_main?is?UI(xml)?file?we?used?in?our?Activity?class.?FrameLayout?is?root?view?of?my?UI(xml)?file.root.setDrawingCacheEnabled(true);Bitmap?bitmap?=?getBitmapFromView(this.getWindow().findViewById(R.id.frameLayout));?//?here?give?id?of?our?root?layout?(here?its?my?FrameLayout's?id)root.setDrawingCacheEnabled(false);

這是getBitmapFromView()方法public?static?Bitmap?getBitmapFromView(View?view)?{

//Define?a?bitmap?with?the?same?size?as?the?view

Bitmap?returnedBitmap?=?Bitmap.createBitmap(view.getWidth(),?view.getHeight(),Bitmap.Config.ARGB_8888);

//Bind?a?canvas?to?it

Canvas?canvas?=?new?Canvas(returnedBitmap);

//Get?the?view's?background

Drawable?bgDrawable?=view.getBackground();

if?(bgDrawable!=null)

//has?background?drawable,?then?draw?it?on?the?canvas

bgDrawable.draw(canvas);

else

//does?not?have?background?drawable,?then?draw?white?background?on?the?canvas

canvas.drawColor(Color.WHITE);

//?draw?the?view?on?the?canvas

view.draw(canvas);

//return?the?bitmap

return?returnedBitmap;

}

它將顯示整個屏幕，包括隱藏在ScrollView

還有另一種更好的截屏方式。

我在這里截了屏幕截圖WebView。WebView?w?=?new?WebView(this);

w.setWebViewClient(new?WebViewClient()

{

public?void?onPageFinished(final?WebView?webView,?String?url)?{

new?Handler().postDelayed(new?Runnable(){

@Override

public?void?run()?{

webView.measure(View.MeasureSpec.makeMeasureSpec(

View.MeasureSpec.UNSPECIFIED,?View.MeasureSpec.UNSPECIFIED),

View.MeasureSpec.makeMeasureSpec(0,?View.MeasureSpec.UNSPECIFIED));

webView.layout(0,?0,?webView.getMeasuredWidth(),

webView.getMeasuredHeight());

webView.setDrawingCacheEnabled(true);

webView.buildDrawingCache();

Bitmap?bitmap?=?Bitmap.createBitmap(webView.getMeasuredWidth(),

webView.getMeasuredHeight(),?Bitmap.Config.ARGB_8888);

Canvas?canvas?=?new?Canvas(bitmap);

Paint?paint?=?new?Paint();

int?height?=?bitmap.getHeight();

canvas.drawBitmap(bitmap,?0,?height,?paint);

webView.draw(canvas);

if?(bitmap?!=?null)?{

try?{

String?filePath?=?Environment.getExternalStorageDirectory()

.toString();

OutputStream?out?=?null;

File?file?=?new?File(filePath,?"/webviewScreenShot.png");

out?=?new?FileOutputStream(file);

bitmap.compress(Bitmap.CompressFormat.PNG,?50,?out);

out.flush();

out.close();

bitmap.recycle();

}?catch?(Exception?e)?{

e.printStackTrace();

}

}

}

},?1000);

}

});

希望這可以幫助..！
