Question

您好我使用手机屏幕进行应用，但此应用程序将所有照片存储在内部存储中的本地文件中，并且当我在手机中打开我的图库时，每张照片都没有显示。

那么如何在Gallery文件夹中存储每张照片？

这里我拿SS＃/ p>

private void takeAScreenshot() {
    Date now = new Date();
    android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
    try {
        String mPath = Environment.getExternalStorageDirectory().toString()
                + "/" + now + ".jpg";
        View v1 = getWindow().getDecorView().getRootView();
        v1.setDrawingCacheEnabled(true);
        Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
        v1.setDrawingCacheEnabled(false);
        File imageFile = new File(mPath);
        FileOutputStream outputStream = new FileOutputStream(imageFile);
        int quality = 100;
        bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
        outputStream.flush();
        outputStream.close();
    } catch (Throwable e) {
        e.printStackTrace();
    }
}

我检查权限

我还找到了来自aparat的保存文件的位置：

/storage/emulated/0/DCIM/Camera/img_name.jpg

我找到了这个，这个有效：

ContentValues values = new ContentValues();
            values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
            values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
            values.put(MediaStore.MediaColumns.DATA, mPath)

但图片保存在图库文件夹和内部存储空间，帮助

Answer 1

保存后使用MediaScanner。

private void takeAScreenshot() {
        Date now = new Date();
        android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
        try {
            String mPath = Environment.getExternalStorageDirectory().toString()
                    + "/" + now + ".jpg";
            View v1 = getWindow().getDecorView().getRootView();
            v1.setDrawingCacheEnabled(true);
            Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
            v1.setDrawingCacheEnabled(false);
            File imageFile = new File(mPath);
            FileOutputStream outputStream = new FileOutputStream(imageFile);
            int quality = 100;
            bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
            outputStream.flush();
            outputStream.close();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        MediaScannerConnection.scanFile(ActivityName.this,
                new String[]{imageFile.toString()}, null,
                new MediaScannerConnection.OnScanCompletedListener() {
                    public void onScanCompleted(final String path, final Uri uri) {
                        ActivityName.this.runOnUiThread(new Runnable() {
                            public void run() {
                                Intent shareIntent = new Intent();
                                shareIntent.setAction(Intent.ACTION_SEND);
                                shareIntent.putExtra(Intent.EXTRA_STREAM,
                                        uri);
                                shareIntent.setType("image/jpeg");
                                startActivity(Intent.createChooser(shareIntent,
                                        "choose one"));
                            }
                        });
                    }
                });
    }

Answer 2

尝试添加此内容：

MediaStore.Images.Media.insertImage(getContentResolver(), yourBitmap, yourTitle , yourDescription);

填写yourBitmap，yourTitle和yourDescription的详细信息，或者将其保留为＆＃34;＆＃34;。
