示例1: getBitmapFromWebView
import android.webkit.WebView; //导入方法依赖的package包/类
@Nullable
public static Bitmap getBitmapFromWebView(WebView webView) {
try {
int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
//Measure WebView's content
webView.measure(widthMeasureSpec, heightMeasureSpec);
webView.layout(0, 0, webView.getMeasuredWidth(), webView.getMeasuredHeight());
//Build drawing cache and store its size
webView.buildDrawingCache();
int measuredWidth = webView.getMeasuredWidth();
int measuredHeight = webView.getMeasuredHeight();
//Creates the bitmap and draw WebView's content on in
Bitmap bitmap = Bitmap.createBitmap(measuredWidth, measuredHeight, Bitmap.Config.ARGB_8888);
