分享图片时出错

Error With sharing image

我想使用 ACTION_SEND 分享图片。所以基本上当用户点击图像并选择 "share image" 时,它应该发送所选图像, 因此,在测试时,我需要使用哪个应用程序来与WhatsApp,Facebook,电子邮件等共享,然后选择任何一个应用程序,然后说"sharing failed, please try again."我似乎无法弄清楚为什么不起作用。但是,我有相同的代码来使用 ACTION_VIEW 全屏显示图像文件,这似乎很好用,但不适用于共享。

public void Onmulti2 (View view) {

    Intent share = new Intent(Intent.ACTION_SEND);

    share.setType("image/*");

    String imagePath = Environment.getExternalStorageDirectory()
            + "/ahmed.jpg";

    File imageFileToShare = new File(imagePath);

    Uri uri = Uri.fromFile(imageFileToShare);
    share.putExtra(Intent.EXTRA_STREAM, uri);

    startActivity(Intent.createChooser(share, "Share Image!"));

}

第一步:先添加权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

第 2 步:编辑

Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");    
sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(imagePath);

设置类型image/jpg而不是图片/*

public void Onmulti2 (View view) {

Intent share = new Intent(Intent.ACTION_SEND);

share.setType("image/jpg");

String imagePath = Environment.getExternalStorageDirectory()
        + "/ahmed.jpg";

File imageFileToShare = new File(imagePath);

Uri uri = Uri.fromFile(imageFileToShare);
share.putExtra(Intent.EXTRA_STREAM, uri);

startActivity(Intent.createChooser(share, "Share Image!"));

}

这对我有用

首先将我的图像存储在外部存储器中

private void SaveImage(Bitmap finalBitmap) {

    String state = Environment.getExternalStorageState();
    if (Environment.MEDIA_MOUNTED.equals(state)) {

        String root = Environment.getExternalStorageDirectory().toString();
        File myDir = new File(root + "/saved_images");
        myDir.mkdirs();
        String fname = "image.jpg";
        File file = new File(myDir, fname);
        if (file.exists()) file.delete();
        try {
            FileOutputStream out = new FileOutputStream(file);
            finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
            out.flush();
            out.close();

        } catch (Exception e) {
            e.printStackTrace();
        }

        MediaScannerConnection.scanFile(this, new String[]{file.toString()}, null,
                new MediaScannerConnection.OnScanCompletedListener() {
                    public void onScanCompleted(String path, Uri uri) {
                        Log.e("ExternalStorage", "Scanned " + path + ":");
                        Log.e("ExternalStorage", "-> uri=" + uri);
                    }
                });
    }
}

## 。 ##

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Bitmap img = BitmapFactory.decodeResource(getResources(), R.drawable.ahmed);
    SaveImage(img);

}

然后从外部存储加载我的图像然后共享它。

    public void Onmulti2 (View view) {

    Intent share = new Intent(Intent.ACTION_SEND);
    share.setType("image/jpeg");
    share.putExtra(Intent.EXTRA_STREAM, Uri.parse("/storage/emulated/0/saved_images/image.jpg"));
    startActivity(Intent.createChooser(share, "Share image using"));
}
