效果：将如图所示的一个LinearLayout分享到qq

布局代码为：

   <!--左边表情处理区域-->
            <LinearLayout
                android:id="@+id/custom_linearlayout"
                android:layout_width="280dp"
                android:layout_height="280dp"
                android:orientation="vertical"
                >
                <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="0dp"
                    android:layout_weight="8"
                    android:background="@drawable/img_visualty2"
                    android:gravity="center"
                    android:orientation="vertical">

                    <ImageView
                        android:id="@+id/img_expression"
                        android:layout_width="90dp"
                        android:layout_height="90dp"
                        android:layout_gravity="center"

                        android:src="@drawable/expression1" />

                </LinearLayout>


                <TextView
                    android:id="@+id/text_expression"
                    android:layout_width="match_parent"
                    android:layout_height="30dp"
                    android:layout_gravity="center"
                    android:background="#fff"
                    android:gravity="center"
                    android:text="暗中观察"
                    android:textSize="18sp" />
            </LinearLayout>

1.定义一个辅助类

            intent.putExtra(Intent.EXTRA_STREAM, uri);
        }

        intent.putExtra(Intent.EXTRA_SUBJECT, msgTitle);
        intent.putExtra(Intent.EXTRA_TEXT, msgText);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        List<PackageInfo> pinfo = packageManager.getInstalledPackages(0);
        for (int i = 0; i < pinfo.size(); i++) {
            if (((PackageInfo) pinfo.get(i)).packageName
                    .equalsIgnoreCase(packageName))
                return true;
        }
        return false;
    }

//    将view转换成bitmap
    public  Bitmap convertViewToBitmap(View view){
        view.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
        view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
        view.buildDrawingCache();
        Bitmap bitmap = view.getDrawingCache();
        return bitmap;
    }
    /**
     * 指定分享到qq
     * @param context
     * @param bitmap
     */
    public void sharedQQ(Activity context, Bitmap bitmap){
        Uri uri = Uri.parse(MediaStore.Images.Media.insertImage(
                context.getContentResolver(), BitmapFactory.decodeResource(context.getResources(), R.drawable.img002), null, null));
        Intent imageIntent = new Intent(Intent.ACTION_SEND);
        imageIntent.setPackage("com.tencent.mobileqq");
        imageIntent.setType("image/*");
        imageIntent.putExtra(Intent.EXTRA_STREAM, uri);
        imageIntent.putExtra(Intent.EXTRA_TEXT,"您的好友邀请您进入天好圈");
        imageIntent.putExtra(Intent.EXTRA_TITLE,"天好圈");
        context.startActivity(imageIntent);
    }
}

2.使用：将一个LinearLayout分享到QQ

LinearLayout custom_linearlayout;
custom_linearlayout= (LinearLayout) findViewById(R.id.custom_linearlayout);
 AndroidShare androidShare=new AndroidShare(this);
                Bitmap bitmap=androidShare.convertViewToBitmap(custom_linearlayout);
                androidShare.shareQQFriend("title","text",1,bitmap);

当然也可以分享到微信好友，朋友圈等

3.若出现权限的问题

Failed to insert image
                                                              java.lang.SecurityException: Permission Denial: writing com.android.providers.media.MediaProvider uri content://media/external/images/media from pid=793, uid=10292 requires android.permission.WRITE_EXTERNAL_STORAGE, or grantUriPermission()
                                                                  at android.os.Parcel.readException(Parcel.java:1665)
。。。。。。。。。。。

见这篇Android6.0权限问题解决：
http://blog.csdn.net/yyl424525/article/details/55254086
将下面的权限加到权限数组即可

Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.READ_EXTERNAL_STORAGE,

附：也可见这位朋友的，原理一样
