I write an algorithm to rename a file, how can I print the current name in the input field?
final EditText input = new EditText(MainActivity.this);
new AlertDialog.Builder(MainActivity.this)
.setTitle("Rename")
.setMessage("Add new name:")
.setView(input)
.setPositiveButton("Ok", new OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString();
if (directory.isDirectory()) {
File from = new File(directory.getAbsolutePath());
File to = new File(directory.getParent() + "/" + value);
from.renameTo(to);
} else {
File from = new File(directory.getAbsolutePath());
File to = new File(directory.getParent() + "/" + value + "." + checkFormat);
from.renameTo(to);
}
go(currentDirectory);
}
}).setNegativeButton("Cancel", new OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Do nothing.
}
}).show();
I would greatly appreciate the help
If I understand correctly, this should work to put the old name in the input box.
File old = null;
if (directory.isDirectory()) {
old = new File(directory.getAbsolutePath());
}
final EditText input = new EditText(MainActivity.this);
input.setText(old.toString());
...
//the rest of your code

I have an edittext that performs an action and if the result of that actions returns an int greater than 1 a dialog box pops up for user input, how can I after the user has inputted data to force enter on the edittext (from_loc_code) again?
from_loc_code being my edittext that already has data
int total_tickets_to_loc = Integer.valueOf(VALUES.total_tickets_to_loc);
if (total_tickets_to_loc > 1) {
// force user to scan product id
AlertDialog.Builder aBuilder = new AlertDialog.Builder(transfer.this);
aBuilder.setTitle("Scan Product");
final EditText input = new EditText(transfer.this);
input.setInputType(InputType.TYPE_CLASS_TEXT);
aBuilder.setView(input);
aBuilder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
final String sText = input.getText().toString().toUpperCase();
VALUES.ticket_product_id = " and p.PRODUCT_ID = '" + sText + "' ";
handler.postDelayed(new Runnable() {
#Override
public void run() {
from_loc_code.requestFocus();
from_loc_code.performClick();
}
}, 200);
}
});
aBuilder.show();
}
I only want my AlertDialog to be dismissed when certain conditions are met (when name and surname given are valid) - else it should always be on top of the parent view. My code is this:
final AlertDialog.Builder alert = new AlertDialog.Builder(this);
final TextView instructions = new TextView(this);
instructions.setText(R.string.alert_enter_data);
final EditText name = new EditText(this);
name.setHint(R.string.name);
final EditText surname = new EditText(this);
surname.setHint(R.string.surname);
LinearLayout ll=new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.addView(instructions);
ll.addView(name);
ll.addView(surname);
alert.setView(ll);
alert.setNeutralButton(R.string.enter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String name_txt = name.getText().toString();
String surname_txt = surname.getText().toString();
if ((name_txt.length() > 1) && (surname_txt.length() > 1)) {
dialog.dismiss();
}
}
});
final AlertDialog alert_dialog = alert.create();
alert_dialog.setCanceledOnTouchOutside(false);
alert_dialog.show();
With this code the AlertDialog disappears when the button is pressed, regardless of the input text. I then tried this:
alert_dialog.setOnShowListener(new DialogInterface.OnShowListener() {
#Override
public void onShow(DialogInterface dialog) {
Button b = alert.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String name_txt = name.getText().toString();
String surname_txt = surname.getText().toString();
String email_txt = email.getText().toString();
String cellphone_txt = cellphone.getText().toString();
String postcode_txt = postcode.getText().toString();
if ((name_txt.length() > 1) && (surname_txt.length() > 1) && (email_txt.length() > 4)) {
if (debug_mode) {Log.i(TAG,"clause 1");}
String data_to_upload = name_txt + ", " + surname_txt + ", " + email_txt + ", "+ cellphone_txt + ", " + postcode_txt + "\n";
// upload_to_github(data_to_upload);
alert_dialog.dismiss();
}
}
});
}
});
But this way I get not Button at all. The Alert Dialog only contains the EditText fields.
alert.setNeutralButton(R.string.enter, new DialogInterface.OnClickListener() {
and
Button b = alert.getButton(AlertDialog.BUTTON_POSITIVE);
both are different buttons.
try
Button b = alert.getButton(AlertDialog.BUTTON_NEUTRAL);
I'm using alert dialog to show some records.those records are comming from db and display in Alertdialog.when user click on item i want to get item name to Log.this is my code.it show item as [test] but i want it showing as test
ArrayList arrayList and String [] categoryStrings initialized on top
List<Video> vd=Video.findWithQuery(Video.class, "select * from Video");
if (vd.size()>0) {
for (Video v : vd) {
arrayList.add(v.getTitle());
}
final List<String> list = Arrays.asList(arrayList.toString());
categoryStrings=new String[list.size()];
categoryStrings=list.toArray(categoryStrings);
AlertDialog.Builder alert = new AlertDialog.Builder(Editmedia.this);
alert.setTitle("Media List");
alert.setCancelable(false);
final int selected = 0; // or whatever you want
alert.setSingleChoiceItems(categoryStrings, selected, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
//onclick
String categoryString = categoryStrings[item];
Log.d("sel", " " + item+" "+categoryString);
edit();
}
});
alert.show();
log value showing
0 [test] i want it as test
Log
Try this, it should help
String categoryString = categoryStrings[item];
categoryString = categoryString.replaceAll("[\\p{Ps}\\p{Pe}]","");
Log.d("sel", " " +" "+categoryString);
[EDIT]
String categoryString = categoryStrings[item];
categoryString = categoryString.replace("[","");
categoryString = categoryString.replace("]","");
Log.d("sel", " " +" "+categoryString);
Try this:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Media List");
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1);
arrayAdapter.clear();
for (int i = 0; i < list.size(); i++) {
Log.i(LOG_TAG, list.get(i));
arrayAdapter.add(list.get(i));
}
builder.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getApplicationContext(), list.get(which),
Toast.LENGTH_LONG).show();
}
});
builder.setPositiveButton("Cancel",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
AlertDialog alert = builder.create();
alert.show();

the permission is added in the

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Emulator SD Card size should be defined
You need to edit your AVD to allot an SD card size to it. You need to launch the AVD Manager dor it of course.
Here's the screen where you add it:
Updating after to include your comments
You're mostly missing the path seperator.
String sdPath = Environment.getExternalStorageDirectory()
.getAbsolutePath() + fileName + ".txt";
must be changed to
String sdPath = Environment.getExternalStorageDirectory()
.getAbsolutePath() +"/"+ fileName + ".txt";
Please add following in your manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Most likely you need to read as well so this is needed for that:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Also note that most likely SD card has different allowed characters so you might need to replace all "|\\?*<\":>+[]/'"; with wanted character like _

Rename the files:
Its working fine:Put this code where you want to change the name.
File sdcard = new File(Environment.getExternalStorageDirectory(), "sample");
String fromFullPath = "/username556596268.mp3";
String toFullPath = "/username.mp3";
File from = new File(sdcard,fromFullPath);
File to = new File(sdcard,toFullPath);
from.renameTo(to);
here "sample" is my sdcard main directory name,"fromFullPath" is my filename it is in inside the sample directory, "toFullPath" is my changed name.
Delete the files:
Its working fine:Put this code where you want to delete file.
File sdcard = new File(Environment.getExternalStorageDirectory(), "sample");
String fromFullPath = "/username556596268.mp3";
File from = new File(sdcard,fromFullPath);
from.delete();
from.deleteOnExit();
