Android屏幕及view的截图实例详解
Android屏幕及view的截图实例详解
屏幕可见区域的截图
整个屏幕截图的话可以用Viewview=getWindow().getDecorView();
publicstaticBitmapgetNormalViewScreenshot(Viewview){
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
returnview.getDrawingCache();
}
scrollview的整体截屏
publicstaticBitmapgetWholeScrollViewToBitmap(Viewview){
view.measure(MeasureSpec.makeMeasureSpec(0,MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0,MeasureSpec.UNSPECIFIED));
view.layout(0,0,view.getMeasuredWidth(),view.getMeasuredHeight());
view.buildDrawingCache();
Bitmapbitmap=view.getDrawingCache();
returnbitmap;
}
webview的整体截图
publicstaticBitmapgetWholeWebViewToBitmap(WebViewwebView){
PicturesnapShot=webView.capturePicture();
Bitmapbmp=Bitmap.createBitmap(snapShot.getWidth(),snapShot.getHeight(),Bitmap.Config.ARGB_8888);
Canvascanvas=newCanvas(bmp);
snapShot.draw(canvas);
returnbmp;
}
listview的整体截图
publicstaticBitmapgetWholeListViewItemsToBitmap(ListViewlistview){
ListAdapteradapter=listview.getAdapter();
intitemscount=adapter.getCount();
intallitemsheight=0;
Listbmps=newArrayList();
for(inti=0;i
需要多次截图的话，需要用到view.destroyDrawingCache();
BitmapnormalViewScreenshot=ScreenShotUtils.getNormalViewScreenshot(mFrameContent);
if(normalViewScreenshot!=null){
Bitmapb=Bitmap.createBitmap(normalViewScreenshot);
mImageResult.setImageBitmap(b);
mFrameContent.destroyDrawingCache();
}
