我有fragment一个画布绘图并将其保存到外部存储器。我通过连接 USB 并搜索文件目录进入设备。我在Android/data/appname/files/img/nameofimage.png. 现在我有一个第二个片段，它在相机拍摄时保存照片，但我找不到它们。
相机
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check that request code matches ours:
if (requestCode == CALL_BACK) {
// Check if your application folder exists in the external storage,
// if not create it:
File imageStorageFolder = new File(
Environment.getExternalStorageDirectory() + File.separator
+ "Camera");
if (!imageStorageFolder.exists()) {
imageStorageFolder.mkdirs();
Log.d("FILE",
"Folder created at: " + imageStorageFolder.toString());
}
// Check if data in not null and extract the Bitmap:
if (data != null) {
String filename = "image";
String fileNameExtension = ".jpg";
File sdCard = Environment.getExternalStorageDirectory();
String imageStorageFolderName = File.separator + "Camera"
+ File.separator;
File destinationFile = new File(sdCard, imageStorageFolderName
+ filename + fileNameExtension);
Log.d("FILE", "the destination for image file is: "
+ destinationFile);
if (data.getExtras() != null) {
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
try {
FileOutputStream out = new FileOutputStream(
destinationFile);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
Log.e("FILE", "ERROR:" + e.toString());
}
}
}
}
}
帆布
capSig.setView(sign = new Sign(this.getActivity(), null))
.setMessage(R.string.store_question)
.setPositiveButton(R.string.save,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
try {
sign.setDrawingCacheEnabled(true);
sign.getDrawingCache()
.compress(
Bitmap.CompressFormat.PNG,
10,
new FileOutputStream(
new File(
getActivity()
.getExternalFilesDir(
"img"),
"signature.png")));
} catch (Exception e) {
Log.e("Error ", e.toString());
}
点击
private class ClickListener implements View.OnClickListener {
@Override
public void onClick(View v) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, CALL_BACK);
}
}
我不完全理解代码，为什么要保存到不同的位置。另外，我需要做什么才能将其保存下来Android/data/appname/files/Camera/？
编辑
logcat 告诉我它被保存在这里：06-08 16:21:49.333: D/FILE(4818): 图像文件的目标是：/storage/emulated/0/Camera/image.jpg我假设它被列为在文件中是私有的，这就是我找不到它的原因。这并没有告诉我为什么它被保存在这里。
第二次编辑
当前代码
private class ClickListener implements View.OnClickListener {
@Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File sdCard = Environment.getExternalStorageDirectory();
String path = sdCard.getAbsolutePath() + "/Camera" ;
File dir = new File(path);
if (!dir.exists()) {
if (dir.mkdirs()) {
}
}
String FileName = "image";
File file = new File(path, FileName + ".jpg");
Uri outputFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, CALL_BACK);
}
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check that request code matches ours:
if (requestCode == CALL_BACK) {
Log.v("RESULT", "Picture Taken");
}
}
