Android截圖的幾種方法

第一種：5.0 之後開放了截圖的方法

if

(build.version.sdk_int >=21)
else
@override
protected
void
onactivityresult
(int requestcode,
int resultcode, intent data)}}
}private
void
parsedata
(intent data)},
300)
;	mvirtualdisplay.
release()
;	mvirtualdisplay = null;
}

public

static bitmap capture
(activity activity)
public
static bitmap shotactivity
(activity ctx)

scrollview 截圖

public

static bitmap shotscrollview
(scrollview scrollview)
bitmap = bitmap.
createbitmap
(scrollview.
getwidth()
, h, bitmap.config.rgb_565)
;final canvas canvas =
newcanvas
(bitmap)
;    scrollview.
draw
(canvas)
;return bitmap;
}

public

static bitmap shotlistview
(listview listview)
bitmap bigbitmap = bitmap.
createbitmap
(listview.
getmeasuredwidth()
, allitemsheight, bitmap.config.argb_8888)
;    canvas bigcanvas =
newcanvas
(bigbitmap)
;    paint paint =
newpaint()
;int iheight =0;
for(
int i =
0; i < bmps.
size()
; i++
)return bigbitmap;
}

public

static bitmap shotrecyclerview
(recyclerview view)
height += holder.itemview.
getmeasuredheight()
;}bigbitmap = bitmap.
createbitmap
(view.
getmeasuredwidth()
, height, bitmap.config.argb_8888)
;      canvas bigcanvas =
newcanvas
(bigbitmap)
;      drawable lbackground = view.
getbackground()
;if(lbackground instanceof
colordrawable
)for
(int i =
0; i < size; i++)}
return bigbitmap;
}

adb shell screencap -p /sdcard/sreenshot1.png

// 第五種：通過 /dev/graphics/fb0 獲取螢幕截圖

fileinputstream graphics = null;

trycatch
(filenotfoundexception e)
datainputstream dstream =
newdatainputstream
(graphics)
;dstream.
readfully
(piex)
;dstream.
close()
;int
colors =
newint
[screenheight * screenwidth]
;// 將rgb轉為色值
for(
int m =
0; m < colors.length; m++
)bitmap bitmap = bitmap.
createbitmap
(colors, screenwidth, screenheight, bitmap.config.argb_8888)
;
