Abh*_*eet 71 android share uri image
我在该应用程序中有图像厨房应用程序我将所有图像放入drawable-hdpi文件夹中.我在我的活动中调用了这样的图像:
private Integer[] imageIDs = {
R.drawable.wall1, R.drawable.wall2,
R.drawable.wall3, R.drawable.wall4,
R.drawable.wall5, R.drawable.wall6,
R.drawable.wall7, R.drawable.wall8,
R.drawable.wall9, R.drawable.wall10
};

所以现在我想知道我如何使用共享Intent我分享这些图像我推出的共享代码如下:
Button shareButton = (Button) findViewById(R.id.share_button);
shareButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(Images.Media.EXTERNAL_CONTENT_URI + "/" + imageIDs);
sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));
}
});

当我点击分享按钮时我也有共享按钮分享框正在打开但当我克服任何服务时,大多数崩溃或一些服务说:无法打开图像所以我怎么能解决这个问题或者是否有任何其他格式代码来共享图像????
编辑:
我尝试使用下面的代码.但它不起作用.
Button shareButton = (Button) findViewById(R.id.share_button);
shareButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse("android.resource://com.android.test/*");
try {
InputStream stream = getContentResolver().openInputStream(screenshotUri);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));
}
});

superM提出的解决方案已经为我工作了很长时间,但最近我在4.2(HTC One)上测试了它并且它在那里停止工作.我知道这是一种解决方法,但它是唯一一款适用于所有设备和版本的解决方案.
根据文档,开发人员被要求"使用系统MediaStore"来发送二进制内容.但是,这具有(不)优势,即媒体内容将永久保存在设备上.
如果这是您的选项,您可能希望授予权限WRITE_EXTERNAL_STORAGE并使用系统范围的MediaStore.
Bitmap icon = mBitmap;
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.MIME_TYPE, "image/jpeg");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI,
values);
OutputStream outstream;
try {
outstream = getContentResolver().openOutputStream(uri);
icon.compress(Bitmap.CompressFormat.JPEG, 100, outstream);
outstream.close();
} catch (Exception e) {
System.err.println(e.toString());
}
share.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(share, "Share Image"));

首先添加权限
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
使用res的位图
Bitmap b =BitmapFactory.decodeResource(getResources(),R.drawable.userimage);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(getContentResolver(),
b, "Title", null);
Uri imageUri = Uri.parse(path);
share.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(share, "Select"));

我发现最简单的方法是使用MediaStore临时存储您要共享的图像:
Drawable mDrawable = mImageView.getDrawable();
Bitmap mBitmap = ((BitmapDrawable) mDrawable).getBitmap();
String path = MediaStore.Images.Media.insertImage(getContentResolver(), mBitmap, "Image Description", null);
Uri uri = Uri.parse(path);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(intent, "Share Image"));

谢谢大家,我尝试了给出的几个选项,但这些选项似乎不适用于最新的 android 版本,因此添加适用于最新 android 版本的修改步骤。这些基于上面的几个答案,但经过修改,解决方案基于文件提供程序的使用:
步骤1
在清单文件中添加以下代码:
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_provider_paths" />
</provider>
Run Code Online (Sandbox Code Playgroud)
步骤:2 在res > xml中创建XML文件
在 xml 中创建 file_provider_paths 文件。
请注意,这是我们在上一步中包含在 android:resource 中的文件。
在file_provider_paths中写入以下代码:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<cache-path name="cache" path="/" />
<files-path name="files" path="/" />
</paths>

步骤:3
之后转到您的按钮单击:
Button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Bitmap bit = BitmapFactory.decodeResource(context.getResources(), R.drawable.filename);
File filesDir = context.getApplicationContext().getFilesDir();
File imageFile = new File(filesDir, "birds.png");
OutputStream os;
try {
os = new FileOutputStream(imageFile);
bit.compress(Bitmap.CompressFormat.PNG, 100, os);
os.flush();
os.close();
} catch (Exception e) {
Log.e(getClass().getSimpleName(), "Error writing bitmap", e);
}
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri imageUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID, imageFile);
intent.putExtra(Intent.EXTRA_STREAM, imageUri);
intent.setType("image/*");
context.startActivity(intent);
}
});

如何在机器上以progamatically方式共享图像,有时您想拍摄视图的快照然后分享它,请按照以下步骤操作:1.添加对mainfest文件的权限

这是一个适合我的解决方案.一个问题是你需要将图像存储在共享或非应用程序的私有位置(http://developer.android.com/guide/topics/data/data-storage.html#InternalCache)
许多建议说要存储在Apps"私有"缓存位置,但这当然不能通过其他外部应用程序访问,包括正在使用的通用共享文件意图.当你尝试这个时,它会运行,但是例如dropbox会告诉你文件不再可用.
/*步骤1 - 使用下面的文件保存功能在本地保存位图文件.*/
localAbsoluteFilePath = saveImageLocally(bitmapImage);
Run Code Online (Sandbox Code Playgroud)
/*步骤2 - 将非私有绝对文件路径共享到共享文件意图*/
if (localAbsoluteFilePath!=null && localAbsoluteFilePath!="") {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
Uri phototUri = Uri.parse(localAbsoluteFilePath);
File file = new File(phototUri.getPath());
Log.d(TAG, "file path: " +file.getPath());
if(file.exists()) {
// file create success
} else {

我厌倦了搜索从我的应用程序到其他应用程序共享视图或图像的不同选项.最后我得到了解决方案.
第1步:共享意图处理阻止.这将弹出您的窗口,其中包含您手机中的应用程序列表
public void share_bitMap_to_Apps() {
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("image/*");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
/*compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] bytes = stream.toByteArray();*/
i.putExtra(Intent.EXTRA_STREAM, getImageUri(mContext, getBitmapFromView(relative_me_other)));
try {
startActivity(Intent.createChooser(i, "My Profile ..."));
} catch (android.content.ActivityNotFoundException ex) {
ex.printStackTrace();
}
}

第2步:将视图转换为BItmap
public static Bitmap getBitmapFromView(View view) {
//Define a bitmap with the same size as the view
Bitmap returnedBitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
//Bind a canvas to it
Canvas canvas = new Canvas(returnedBitmap);
//Get the view's background
Drawable bgDrawable = view.getBackground();
if (bgDrawable != null)
//has background drawable, then draw it on the canvas
bgDrawable.draw(canvas);
else
//does not have background drawable, then draw white background on the canvas
canvas.drawColor(Color.WHITE);
// draw the view on the canvas
view.draw(canvas);
//return the bitmap
return returnedBitmap;
}

第3步:
从位图图像获取URI
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
