篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Android实现截屏和截长图功能的各种方法相关的知识，希望对你有一定的参考价值。
微信好友或者朋友圈的分享，可以是普通的截图分享，也可以是截取长图的分享，甚至还会有需求让你拼上生成的二维码和logo图片，下面我们直接来看看这些方法的使用：
先说一下拼接三张不同的图片后有黑色背景的解决方案(在下面的6拼接合成图片的方法里加上就可以了)：
//设置画布背景色为白色，即自定义控件显示的背景色为白色：
canvas.drawRGB(255,255,255);1.普通的截屏方法
/**
* 截屏
*
* @param activity
* @return
*/
public static Bitmap activityShot(Activity activity)
/*获取windows中最顶层的view*/
View view = activity.getWindow().getDecorView();
//允许当前窗口保存缓存信息
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
//获取状态栏高度
Rect rect = new Rect();
view.getWindowVisibleDisplayFrame(rect);
int statusBarHeight = rect.top;
WindowManager windowManager = activity.getWindowManager();
//获取屏幕宽和高
DisplayMetrics outMetrics = new DisplayMetrics();
windowManager.getDefaultDisplay().getMetrics(outMetrics);
int width = outMetrics.widthPixels;
int height = outMetrics.heightPixels;
//去掉状态栏
Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache(), 0, statusBarHeight, width, height - statusBarHeight);
//销毁缓存信息
view.destroyDrawingCache();
view.setDrawingCacheEnabled(false);
return bitmap;
2.截取scrollView的屏幕方法
/**
* 截取scrollview的屏幕
* @param scrollView
* @return
*/
public static Bitmap getBitmapByView(ScrollView scrollView)
int h = 0;
Bitmap bitmap = null;
// 获取listView实际高度
for (int i = 0; i < scrollView.getChildCount(); i++)
h += scrollView.getChildAt(i).getHeight();
scrollView.getChildAt(i).setBackgroundResource(R.drawable.white_drawable);
// 创建对应大小的bitmap
bitmap = Bitmap.createBitmap(scrollView.getWidth(), h,
Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(bitmap);
scrollView.draw(canvas);
// 测试输出
FileOutputStream out = null;
try
out = new FileOutputStream("/sdcard/screen_test.png");
catch (FileNotFoundException e)
e.printStackTrace();
try
if (null != out)
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
catch (IOException e)
// TODO: handle exception
return bitmap;
3.截取ListvListView的屏幕方法
/**
* 截图listview
* **/
public static Bitmap getbBitmap(ListView listView)
int h = 0;
Bitmap bitmap = null;
// 获取listView实际高度
for (int i = 0; i < listView.getChildCount(); i++)
h += listView.getChildAt(i).getHeight();
// 创建对应大小的bitmap
bitmap = Bitmap.createBitmap(listView.getWidth(), h,
Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(bitmap);
listView.draw(canvas);
// 测试输出
FileOutputStream out = null;
try
out = new FileOutputStream("/sdcard/screen_test.png");
catch (FileNotFoundException e)
e.printStackTrace();
try
if (null != out)
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
catch (IOException e)
// TODO: handle exception
return bitmap;
4.截取线性布局或相对布局屏幕的方法
/**
* 截取RelativeLayout
**/
public static Bitmap getRelativeLayoutBitmap(RelativeLayout relativeLayout)
int h = 0;
Bitmap bitmap;
for (int i = 0; i < relativeLayout.getChildCount(); i++)
h += relativeLayout.getChildAt(i).getHeight();
// 创建对应大小的bitmap
bitmap = Bitmap.createBitmap(relativeLayout.getWidth(), h,
Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(bitmap);
relativeLayout.draw(canvas);
return bitmap;
/**
* 截取LinearLayout
**/
public static Bitmap getLinearLayoutBitmap(LinearLayout linearLayout)
int h = 0;
Bitmap bitmap;
for (int i = 0; i < linearLayout.getChildCount(); i++)
h += linearLayout.getChildAt(i).getHeight();
// 创建对应大小的bitmap
bitmap = Bitmap.createBitmap(linearLayout.getWidth(), h,
Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(bitmap);
linearLayout.draw(canvas);
return bitmap;
5.截取除了导航栏之外的整个屏幕
/**
* 截取除了导航栏之外的整个屏幕
*/
public static Bitmap screenShotWholeScreen(Activity activity)
View dView = activity.getWindow().getDecorView();
dView.setDrawingCacheEnabled(true);
dView.buildDrawingCache();
Bitmap bitmap = Bitmap.createBitmap(dView.getDrawingCache());
return bitmap;
6.拼接合成图片的方法
//合成三张图片
private static Bitmap mergeBitmap(Bitmap firstBitmap, Bitmap secondBitmap, Bitmap threeBitmap)
Bitmap bitmap = Bitmap.createBitmap(firstBitmap.getWidth(), firstBitmap.getHeight() + secondBitmap.getHeight() + threeBitmap.getHeight(), firstBitmap.getConfig());
Canvas canvas = new Canvas(bitmap);
canvas.drawBitmap(firstBitmap, new Matrix(), null);
canvas.drawBitmap(secondBitmap, 0, firstBitmap.getHeight(), null);
canvas.drawBitmap(threeBitmap, secondBitmap.getWidth(), firstBitmap.getHeight(), null);
return bitmap;
//合成两张图片
public static Bitmap mergeBitmap(Bitmap firstBitmap, Bitmap secondBitmap)
Bitmap bitmap = Bitmap.createBitmap(firstBitmap.getWidth(), firstBitmap.getHeight(),firstBitmap.getConfig());
Canvas canvas = new Canvas(bitmap);
canvas.drawBitmap(firstBitmap, new Matrix(), null);
canvas.drawBitmap(secondBitmap, 0, 0, null);
return bitmap;
7.具体的调用和拼接合成图片：
Bitmap bitmap = StringUtil.activityShot(JCZQTDetailActivity.this);
Bitmap bitmap = StringUtil.getBitmapByView(scrollView_jc_type);//截取长图
// Bitmap bitmap = StringUtil.getRelativeLayoutBitmap(rl_jc_all);
// Bitmap bitmap1 = StringUtil.screenShotWholeScreen(JCZQTDetailActivity.this);
// Bitmap bitmap2 = ShareUtil.mergeBitmap(bitmap, bitmap1);ShareUtil.weiChatPic(Constants.wx_api, 7, MakeReceiptDetailsActivity.this, bitmap2);8.微信分享图片方法和链接生成二维码图片方法：
/**
* 分享 图片
*/
public static void weiChatPic(IWXAPI api, int flag, Context context, Bitmap bitmap)
if (api.isWXAppInstalled()) //判断微信是否安装
//Bitmap mWXShareBitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.logo_icon);//将截屏得到的bitmap赋值
GlobalLog.e("sgf", "-------GlobalEntity.USER.getUrl()-------" + GlobalConfig.getURL(context));
if ("".equals(GlobalConfig.getURL(context)) || "null".equals(GlobalConfig.getURL(context)))
Intent intent = new Intent(context, LoginActivity.class);
context.startActivity(intent);
return;
loadRQInfo(GlobalConfig.getURL(context));
Bitmap b = BitmapFactory.decodeResource(context.getResources(), R.drawable.sharewinlogo);
GlobalLog.e("sgf", "-------bitmap-------" + bitmap);
GlobalLog.e("sgf", "-------bitmaps-------" + bitmaps);
GlobalLog.e("sgf", "-------b-------" + b);
Bitmap bitmap1 = mergeBitmap(bitmap, bitmaps, b);
WXImageObject imgObject = new WXImageObject(bitmap1);
//imgObject.imagePath
WXMediaMessage mediaMessage = new WXMediaMessage();
mediaMessage.mediaObject = imgObject;
//设置缩略图
Bitmap thumbBmp = Bitmap.createScaledBitmap(bitmap1, bitmap1.getWidth() / 10, bitmap1.getHeight() / 10, true);
mediaMessage.thumbData = bmpToByteArray(thumbBmp, true);
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = buildTransaction("img");//分享类型是图片
req.message = mediaMessage;
//表示发送给朋友圈 WXSceneTimeline 表示发送给朋友 WXSceneSession
req.scene = flag == 7 ? SendMessageToWX.Req.WXSceneSession : SendMessageToWX.Req.WXSceneTimeline;
api.sendReq(req);
GlobalLog.e("sgf", "-------end-------");
else
Toast.makeText(context, "您没有安装微信客户端", Toast.LENGTH_SHORT).show();
/**
* 生成万二维码
*
* @param soldUrl
*/
private static void loadRQInfo(String soldUrl)
//回收bitmaps
if (null != bitmaps && !bitmaps.isRecycled())
bitmaps.recycle();
bitmaps = null;
try
bitmaps = StringUtil.makeQRImage(soldUrl, 480, 350);
catch (WriterException e)
e.printStackTrace();
