i want to save a view, when i run the app everything is working fine, but i am unable to find saved file/s in the internal storage of the phone. Any help would be appreciated as i am new and unable to sort out what is going wrong . here is my code
public void saveMe(View v) {
// get prompts.xml view
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.prompt, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set prompt.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialog);
// set dialog message
alertDialogBuilder.setCancelable(false);
alertDialogBuilder.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
final String fileName = userInput.getText().toString();
final View view1=findViewById(R.id.relativeLayout); // The view that you want to save as an image
Bitmap bitmap = Bitmap.createBitmap(view1.getWidth(), view1.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(bitmap);
view1.draw(c);
if(fileName.length() == 0)
Toast.makeText(EidCardFinal.this,"Please Enter File Name",Toast.LENGTH_SHORT).show();
else{
File file = new File(context.getFilesDir(), fileName);
if (file.exists())
Toast.makeText(EidCardFinal.this,"File Already Exists",Toast.LENGTH_SHORT).show();
else{
try{
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, out);
Toast.makeText(EidCardFinal.this,"File Saved",Toast.LENGTH_SHORT).show();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
}
});
alertDialogBuilder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
}

I'm getting an error in this method: "The constructor Object(EditText) is undefined"
private void setupAlert()
{
Log.d(TAG, "setupAlert()");
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.emaildialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText)promptsView.findViewById(R.id.editTxtEmailAddress);
alertDialogBuilder.setCancelable(false).setPositiveButton("OK", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int id)
{
updatePref(userInput.getText().toString());
Log.d(MainActivity.TAG, "setupAlert: getPreference()=" + getPreference());
takeSnapNow();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.colour_selector);
Log.d(TAG, "onCreate: getPreference()=" + getPreference());
if (getPreference().equals("")) {
setupAlert();
takeSnapNow();
} else {
takeSnapNow();
}
}
private void takeSnapNow()
{
String fileName = "TempImage.jpg";
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION, "Captured by XYZ app");
imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
Please suggest the solution to this error.
Edit: Corrected the above error by removing UserInput as suggested by others. However the alertDialog is still not shown. The logic is to check the sharedpref initially in onCreate, and if not found, call setupAlert() method to get email ID from user.
Any clues? Changed code updated in the above snippet.
DialogInterface.OnClickListener doesn't take an EditText as a constructor parameter and you don't need to do that ! you can use userInput without passing it to DialogInterface.OnClickListener, just use it as follow
alertDialogBuilder.setCancelable(false).setPositiveButton("OK", new DialogInterface.OnClickListener() {
Why are you using "new DialogInterface.OnClickListener(userInput)"?
Just use new DialogInterface.OnClickListener()
In my android app, I'm producing a lot of data which I store at the moment in a .txt file simply called "logData". Now my boss wants me to give him the possibility to save it as an extra file, like the Save As Button in various windows programms.
At the moment I have a method for generating a logFile and write first data to it and one for writing all coming data to it. But how can I implement a "Save as" functionality?
Here the code of both methods and the used variables:
private String logData = "logData.txt";
private String logText = "";
private File extStorageDir = Environment.getExternalStorageDirectory();
private File mLogFile = new File(extStorageDir, "DCULogData/logData.txt");
generating:
public void generateLogFileOnSD(String sFilename, String sBody) {
try {
File logFile = new File(extStorageDir, sFilename);
FileWriter writer = new FileWriter(logFile);
writer.append(sBody);
writer.flush();
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}
writing:
public void writeLogFileOnSD(String sFilename, String sBody) {
if (mLogFile.exists()) {
try {
FileOutputStream fOut = new FileOutputStream(mLogFile);
OutputStreamWriter mOutWriter = new OutputStreamWriter(fOut);
mOutWriter.append(sBody);
mOutWriter.close();
fOut.close();
} catch (IOException e) {
e.printStackTrace();
}
} else {
generateLogFileOnSD(logData, logText);
}
}
EDIT : This is my solution based on Simple Plan's answer. Thanks for this!
I also tested some scenarios with filenames like "/blabla", "m/m/m/m/m/". No failure found until now :)
public Button.OnClickListener saveLogFileOnClickListener = new Button.OnClickListener() {
public void onClick(View v) {
AlertDialog.Builder builder = new AlertDialog.Builder(
DiagnosisActivity.this);
builder.setTitle(R.string.save_file_dialog);
builder.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
final EditText input = new EditText(
DiagnosisActivity.this);
input.setSingleLine();
AlertDialog.Builder ad = new Builder(
DiagnosisActivity.this);
ad.setTitle("Enter save as File Name");
ad.setView(input);
ad.setCancelable(true);
ad.setPositiveButton("Save as",
new DialogInterface.OnClickListener() {
#Override
public void onClick(
DialogInterface dialog,
int which) {
int len = input.length();
if (len != 0) {
final_filename = input
.getText().toString()
.trim();
generateLogFileOnSD(
"DCULogData/"
+ final_filename
+ ".txt",
ReceiverThread
.getLogText());
Toast.makeText(
getApplicationContext(),
"Saved!",
Toast.LENGTH_LONG)
.show();
} else {
Toast.makeText(
getApplicationContext(),
"Enter a proper name",
Toast.LENGTH_LONG)
.show();
}
}
});
ad.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog,
int which) {
dialog.cancel();
}
});
AlertDialog alert = ad.create();
alert.show();
}
});
builder.setNegativeButton("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog alert1 = builder.create();
alert1.show();
}
};
First add Button into your Layout as a text Save as and implement OnClickListner()
String final_filename;
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
annual_crop.setTextColor(Color.BLUE);
AlertDialog.Builder al1 = new Builder(youractivity);
al1.setMessage("Do you want to save a file?");
al1.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog,
int which) {
final EditText input = new EditText(
youractivity.this);
input.setSingleLine();
AlertDialog.Builder al = new Builder(
AgriListView.this);
al.setTitle("Enter save as File Name");
al.setView(input);
al.setCancelable(true);
al.setIcon(R.drawable.bt);
al.setPositiveButton(
"Save as",
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog,
int which) {
int len = input
.length();
if (!(len == 0)) {
final_filename=input.getText().toString.trim();
);
} else {
Toast.makeText(
getApplicationContext(),
"Enter Name Properly",
Toast.LENGTH_LONG)
.show();
}
}
});
al.setNegativeButton(
"Cancel",
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog,
int which) {
dialog.cancel();
}
});
AlertDialog alert = al.create();
alert.show();
}
});
al1.setNegativeButton("No",
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog,
int which) {
dialog.cancel();
}
});
AlertDialog alert1 = al1.create();
alert1.show();
}
});
}
});
And used final_filename like below:
File folder = new File(Environment.getExternalStorageDirectory(), "DCULogData");
File mLogFile = new File(folder.getPath(), final_filename);
And add permission in your manifest.xml file
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I'm having some trouble with displaying multiple popups. Right now I have an AlertDialog that pops up with an EditView for the user to put in the name of the file they want to make, which I would then pass into a File object and then a Writer and a new Dialog is supposed to pop up asking the user if they want to launch the music player.
However, as things are now, after I press 'Ok' on the first AlertDialog, absolutely nothing happens. I'm not sure what I'm doing wrong. Any help? Here is my code.
//naming the playlist
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Exporting Playlist");
alert.setMessage("Enter the name of the playlist!");
// Set an EditText view to get user input
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
name = input.getText().toString() + ".m3u";
popup = true;
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
alert.show();
//after the playlist is named, put songs into file
if (popup){
popup = false;
final File list = new File(mp3folderPath + name);
FileWriter writer;
BufferedWriter write;
ArrayList<String> playlist = new ArrayList<String>();
Log.d("poo", "mAdapter count: "+mAdapter.getCount());
for (int i=0; i < mAdapter.getCount(); i++) {
playlist.add(mAdapter.getItem(i));
}
Log.d("poo", playlist.toString());
//write the songs to the m3u playlist
writer = new FileWriter(list);
write = new BufferedWriter(writer);
for (int i = 0; i<playlist.size(); i++){
String[] name = playlist.get(i).split(" : ");
Log.d("poo", name[0]);
write.append(name[0]+"\n");
}
write.close();
//popup window
CharSequence choices[] = new CharSequence[] {"Launch Music Player", "Quit"};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Exported playlist!");
builder.setItems(choices, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
if (which == 0) {
Intent intent = new Intent(MediaStore.INTENT_ACTION_MUSIC_PLAYER);
startActivity(intent);
finish();
}
else {
finish();
}
}
});
builder.show();
}
}
To show sequential popup, the conditions and code for consecutive popup(s) would have to be reachable from one to the other.
AlertDialog1 has to contain the code which would show AlertDialog2...
Try something like this:
//naming the playlist
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Exporting Playlist");
alert.setMessage("Enter the name of the playlist!");
// Set an EditText view to get user input
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//check if the name is not null
name = input.getText().toString() + ".m3u";
//Now instead of popup = true;
//call func to name the playlist and next dialog
callNextDialog();
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
alert.show();
//after the playlist is named, put songs into file
// if (popup){
// popup = false;
// }
public void callNextDialog(){
final File list = new File(mp3folderPath + name);
FileWriter writer;
BufferedWriter write;
ArrayList<String> playlist = new ArrayList<String>();
Log.d("poo", "mAdapter count: "+mAdapter.getCount());
for (int i=0; i < mAdapter.getCount(); i++) {
playlist.add(mAdapter.getItem(i));
}
Log.d("poo", playlist.toString());
//write the songs to the m3u playlist
writer = new FileWriter(list);
write = new BufferedWriter(writer);
for (int i = 0; i<playlist.size(); i++){
String[] name = playlist.get(i).split(" : ");
Log.d("poo", name[0]);
write.append(name[0]+"\n");
write.close();
//popup window
CharSequence choices[] = new CharSequence[] {"Launch Music Player", "Quit"};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Exported playlist!");
builder.setItems(choices, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
if (which == 0) {
Intent intent = new Intent(MediaStore.INTENT_ACTION_MUSIC_PLAYER);
startActivity(intent);
finish();
}
else {
finish();
}
}
});
builder.show();
}
}
AlertDialog.show() doesn't wait for the dialog to go away. It returns immediately. That means ALL of the logic of what to do after the user makes a choice has to go in the onClick function of the dialog's positive button.
Basically, everything in your if(popup) code needs to be in the onClick handler
I am using this tutorial to learn how to connect to Facebook via Android app. I am particularly interested in the section where he shows how to post something on the wall / status of the user.
The tutorial is fairly straightforward however my requirement is that I need to let the app append things along with what the user posts.
How can that be achieved ?
You can do something like this:
private void publishToFacebook(String message)
{
long songId = MusicUtils.getCurrentAudioId();
long albumId = MusicUtils.getCurrentAlbumId();
String albumartUrl = MusicUtils.getArtworkUrlFromExtrasCache(getApplicationContext(),albumId);
Bitmap bm = MusicUtils.getArtworkFromExtrasCache(getApplicationContext(),albumId,false,false);
if(bm == null)
bm = MusicUtils.getDefaultArtwork(getApplicationContext());
shareFacebookConnector = new ShareConnector(MediaPlaybackActivity.this, getApplicationContext());
shareFacebookConnector.setCurrentAlbum(MusicUtils.getCurrentAlbumName());
shareFacebookConnector.setCurrentArtist(MusicUtils.getCurrentArtistName());
shareFacebookConnector.setCurrentTrack(MusicUtils.getCurrentTrackName());
shareFacebookConnector.setCurrentCoverArt(bm);
if(albumartUrl != null)
{
shareFacebookConnector.setCurrentCoverUrl(albumartUrl);
}
LayoutInflater inflater = this.getLayoutInflater();
final View dialoglayout = inflater.inflate(R.layout.facebook_share, (ViewGroup) findViewById(R.id.facebook_share_root));
final ImageView image = (ImageView) dialoglayout.findViewById(R.id.facebook_cover_view);
input = (EditText) dialoglayout.findViewById(R.id.facebook_share_content);
ContextThemeWrapper ctw = new ContextThemeWrapper(this, R.style.AlertDialogCustom);
AlertDialog.Builder alert = new AlertDialog.Builder(ctw);
if(message != null)
{
shareFacebookConnector.publishToFacebook(alert, input, message);
}
else
{
shareFacebookConnector.publishToFacebook(alert, input, null);
}
alert.setView(dialoglayout);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
bAlertInProgress = false;
String messageToPost = input.getText().toString();
shareFacebookConnector.postMessageToWall(messageToPost, false);
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
bAlertInProgress = false;
Toast.makeText(MediaPlaybackActivity.this, "Wall post cancelled !", Toast.LENGTH_SHORT).show();
//finish();
}
});
bAlertInProgress = true;
mShareKey = "********";
alertDialog = alert.create();
alertDialog.show();
}
You have to open the session as session.openForPublish(); and you required permission "publish_action"
How come the AlertDialog that has the title "Location was saved to file" doesn't show up? It is the one that should be displayed after the user presses Okay on the first dialog.
I think it has something to do with threads, but I'm not sure.
SimpleDateFormat timeStampFormat = new SimpleDateFormat("MMMMM-dd-yyyy");
final EditText input = new EditText(EncounterActivity.this);
input.setWidth(75);
input.setText("Bear-Encounter-GPS-" + timeStampFormat.format(new Date()) + ".txt");
new AlertDialog.Builder(EncounterActivity.this)
.setTitle("Save GPS Location")
.setMessage("Please enter a filename")
.setView(input)
.setIcon(R.drawable.gps)
.setPositiveButton("Save", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
try {
File root = Environment.getExternalStorageDirectory();
if (root.canWrite()){
File fn = new File(root, input.getText().toString());
FileWriter gpxwriter = new FileWriter(fn);
BufferedWriter out = new BufferedWriter(gpxwriter);
out.write(ll.toUTMRef().toString());
out.close();
AlertDialog.Builder builder = new AlertDialog.Builder(EncounterActivity.this);
builder.setIcon(R.drawable.gps);
builder.setTitle("Location was saved to file");
builder.setMessage("Your GPS coordinates were saved to " + fn.getAbsolutePath())
.setPositiveButton("Okay", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
AlertDialog alert = builder.create();
alert.show();
}
} catch (IOException e) {
//ProfitBandit.alert(Shipment.this, "Couldn't write the file.");
Log.v("IOException", "Could not write file " + e.getMessage());
}
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Do nothing.
}
}).show();
You CAN display an alert dialog from an alert dialog if you use the pattern showDialog(int) getInstanceSomeDialog and onCreateDialog(int) for both dialogs. So in my aboutAlertDialog I have:
builder.setPositiveButton("View EULA", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) { //cancels itself?
showDialog(DIALOG_EULA_SHOW);
}
});
which in turn displays an EULA in yet another AlertDialog. OR you could just toss up a Toast as in:
Toast.makeText(Main.this,"Location Saved.", Toast.LENGTH_SHORT).show();
where Main is the activity class.
