public class ShareTools { private static final String[] PERMISSION_EXTERNAL_STORAGE = new String[]{ Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE}; private static final int REQUEST_EXTERNAL_STORAGE = 100; //本地路径:将图片发送到朋友 public static void shareToWeChatFriend(Activity activity, String filePath) { if (isWeixinAvilible(activity)){ //authority 需要替换,还需要有SD卡权限 Uri uriForFile = FileProvider.getUriForFile(activity, "com.ksk.android.fileProvider", new File(filePath)); Intent intent = new Intent(Intent.ACTION_SEND); intent.putExtra(Intent.EXTRA_STREAM, uriForFile); intent.putExtra("android.support.v4.app.EXTRA_CALLING_PACKAGE", activity.getPackageName()); intent.putExtra("android.support.v4.app.EXTRA_CALLING_ACTIVITY", activity.getComponentName()); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET); intent.setType(activity.getContentResolver().getType(uriForFile)); intent.setClassName("com.tencent.mm", "com.tencent.mm.ui.tools.ShareImgUI"); intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); boolean hasPermission = true; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { hasPermission = activity.checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED; } if (!hasPermission) { Toast.makeText(activity,"请允许权限,否则无法分享!",Toast.LENGTH_SHORT).show(); verifyStoragePermissions(activity); } else { activity.startActivity(intent); } }else { //没有安装微信 Toast.makeText(activity,"请先安装微信",Toast.LENGTH_SHORT).show(); } } //本地路径:将图片发送到朋友圈 public static void shareToWeChatTimeLine(Activity activity, String filePath) { if (isWeixinAvilible(activity)){ //authority 需要替換,还需要有SD卡权限 Uri uriForFile = FileProvider.getUriForFile(activity, "com.ksk.android.fileProvider", new File(filePath)); Intent intent = new Intent(Intent.ACTION_SEND); intent.putExtra("android.support.v4.app.EXTRA_CALLING_PACKAGE", activity.getPackageName()); intent.putExtra("android.support.v4.app.EXTRA_CALLING_ACTIVITY", activity.getComponentName()); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET); intent.putExtra(Intent.EXTRA_STREAM, uriForFile); intent.setType(activity.getContentResolver().getType(uriForFile)); intent.setClassName("com.tencent.mm", "com.tencent.mm.ui.tools.ShareToTimeLineUI"); intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); boolean hasPermission = true; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { hasPermission = activity.checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED; } if (!hasPermission) { Toast.makeText(activity,"请允许权限,否则无法分享!",Toast.LENGTH_SHORT).show(); verifyStoragePermissions(activity); } else { activity.startActivity(intent); } }else { //没有安装微信 Toast.makeText(activity,"请先安装微信",Toast.LENGTH_SHORT).show(); } } public static void shareBmpToWeChatFriend(Activity context,Bitmap bmp){ String uri = saveImageToGallery(bmp); shareToWeChatFriend(context,uri); } public static void shareBmpToWeChatTimeLine(Activity context,Bitmap bmp){ String uri = saveImageToGallery(bmp); shareToWeChatTimeLine(context,uri); } public static String saveImageToGallery(Bitmap bmp) { String root = Environment.getExternalStorageDirectory().getAbsolutePath(); String dirName = "sky"; File appDir = new File(root, dirName); if(!appDir.exists()) { appDir.mkdirs(); } long timeStamp = System.currentTimeMillis(); String fileName = timeStamp + ".jpg"; File file = new File(appDir, fileName); FileOutputStream fos = null; try { fos = new FileOutputStream(file); bmp.compress(Bitmap.CompressFormat.JPEG, 100, fos); fos.flush(); //发送广播刷新 //context.sendBroadcast(new Intent("android.intent.action.MEDIA_SCANNER_SCAN_FILE", Uri.fromFile(new File(file.getPath())))); byte var10 = 2; return file.getPath(); } catch (FileNotFoundException var22) { var22.printStackTrace(); } catch (IOException var23) { var23.printStackTrace(); } finally { try { if(fos != null) { fos.close(); } } catch (IOException var21) { var21.printStackTrace(); } } return null; } //是否安装微信 private static boolean isWeixinAvilible(Context context) { final PackageManager packageManager = context.getPackageManager();// 获取packagemanager List pinfo = packageManager.getInstalledPackages(0);// 获取所有已安装程序的包信息 if (pinfo != null) { for (int i = 0; i < pinfo.size(); i++) { String pn = pinfo.get(i).packageName; if (pn.equals("com.tencent.mm")) { return true; } } } return false; } //动态获取权限 private static boolean verifyStoragePermissions(Activity activity) { int permissionWrite = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE); if (permissionWrite != PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions(activity, PERMISSION_EXTERNAL_STORAGE, REQUEST_EXTERNAL_STORAGE); return false; } else { return true; } }} 不要忘记了,清单文件添加权限:
res目录添加xml文件夹,并在xml文件夹中添加 file_paths.xml 文件,内容为:
<?xml version="1.0" encoding="utf-8"?> 清单文件继续添加:
完成!
