I've got an activity where I can add bookmarks to a favourites list. Each favourite has got a button. When I click that button I have to go to that specific activity. But it shows me an error. The app doesn't crash, but the bookmarked activity isn't started from the click.
Here is the code for the "Favourites" activity:
public class FavouritesActivity extends Activity {
private TextView mEmptyText;
private LinearLayout mBookmarkLayout;
private Context mContext;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.favourites_layout);
mContext = this;
mEmptyText = (TextView) findViewById(R.id.empty_textview);
mBookmarkLayout = (LinearLayout) findViewById(R.id.bookmark_insert_point);
getAllKeys();
}
private void getAllKeys()
{
SharedPreferences sp = this.getSharedPreferences("favs", MODE_PRIVATE);
Map<String,?> keys = sp.getAll();
int count = 0;
for(Map.Entry<String,?> entry : keys.entrySet())
{
String value = entry.getValue().toString();
System.out.println("!!!!!!!!!!!!!!!!!value = "+value);
String delimiter = ",";
String[] values_array = value.split(delimiter);
addBookmark(values_array);
count++; //keep track of the number of bookmarks
}
//if there are no bookmarks, display a text view saying so. Otherwise, make the text view go away
if (count == 0)
{
mEmptyText.setVisibility(View.VISIBLE);
mEmptyText.setText(getString(R.string.no_favs));
}
else
mEmptyText.setVisibility(View.GONE);
}
private void addBookmark(String[] values_array)
{
LayoutInflater vi = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = vi.inflate(R.layout.fav_individual, null);
TextView text = (TextView) v.findViewById(R.id.bookmark_text);
text.setSelected(true);
ImageButton button = (ImageButton) v.findViewById(R.id.bookmark_button);
v.getContext();
text.setText(values_array[1]);
final String myClass = values_array[0];
button.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Class<?> cl = null;
try {
cl = Class.forName(myClass);
Intent myIntent = new Intent(mContext, cl);
startActivity(myIntent);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
});
// insert into main view
mBookmarkLayout.addView(v, 0, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));
System.out.println("!!!!!!!!!!!!!!!!!!!!Just added a view");
}
}
The error is the onClick method, exactly in this line:
cl = Class.forName(myClass);
It gives me a ClassNotFoundException.
It seems that with this code I'm able to start an activity which is inside this package. But the problem is that the activity I want to start is inside a different package. The logcat says that it coulnd't find the activity in the current package.
So how can I open an activity from a different package in my case? Tha activity is declared in the manifest file.
Thank you.
Did you import the other package in your FavouritesActivity ?
Add this line at the top of your code and replace the words to match with your other package:
import com.yourotherpackage.name.yourclassname;

I made a TableLayout 3x3 in "Activity A"(Chose a Table Layout, because I thought it suits my needs)
7 of the 9 cells are clickable and open "Activity B" which is a custom number picker I made.
I used an intent to pass an array and other data to activiy B
The idea of my number picker is to set a value in the cell I just clicked in Activiy A(I wanted something like the calendarDatePicker)
In "Activity B" I have a method to update the values from "Activity A" and finish() "Activity B" when an image View is clicked wich works very fine except that it does not set the value for the clicked Text View
How can I set the TextValue from another activity when the TextValue is contained in a Table Layout?
I don't use intent, because honestly I don't know how to handle it when the "Activity B" is closed.
I mean where in "Activity A" should I handle this intent from "Activity B"
Using the debugger I found out that trying to set the text using the TextView Id does not works as it shows a "null" object in the debugger.
Activiy A
package com.example.racu.threebythree;
public class threebythree extends AppCompatActivity {
public static ArrayList<Integer> ColumnA = new ArrayList<Integer>();
public static ArrayList<Integer> ColumnB = new ArrayList<Integer>();
public static ArrayList<Integer> ColumnC = new ArrayList<Integer>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_three_by_three);
for (int i = 1; i < 28; i++) {
if (i > 0 && i < 10)
ColumnA.add(i);
if (i > 10 && i < 19)
ColumnB.add(i);
if (i > 19 && i < 28)
ColumnC.add(i);
}
}
public void openNumberPicker(View v) {
// I used this to "guess" the location of the cell in the table layout as I could not find a way to do it.
String cellName = v.getResources().getResourceName(v.getId());
String cellLetter = cellName.substring(cellName.lastIndexOf("/") + 1);
// Send intent
Intent intent = new Intent(this, NumberPicker.class);
intent.putExtra("Id", (cellLetter.substring(0, 1) + cellLetter.substring(2)).toUpperCase());
switch (cellLetter.substring(0, 1)) {
case ("a"):
intent.putIntegerArrayListExtra("Column", ColumnA);
break;
case ("b"):
intent.putIntegerArrayListExtra("Column", ColumnB);
break;
case ("c"):
intent.putIntegerArrayListExtra("Column", ColumnC);
break;
}
intent.putExtra("Cell ID", v.getId());
startActivity(intent);
}
}

// Here I try to Set the text to the cell in Activity A, using its R.id, but in the debugger I get a null reference, therefore my app crashes

Thanks to Pavan for the hint I found two more very helpful post here and this one was EXACTLY what I was looking for.
Like that ( make sure you give the TableLayout an id ):
TableLayout tl = (TableLayout)findViewById( R.id.tableLayout );
TextView tv = (TextView)tl.findViewById( R.id.textView );
problem: I set point breaks at the following code:
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_NAME, workoutName);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_DAYS, workoutDays);
, both showed up as null when I ran the app in debug mode. workoutName contains a simple String that is passed to a new activity, whereas workoutDays constains an array of String.
the full code is provided below:
public class CreateWorkoutActivity extends Activity {
public final String TAG = this.getClass().getSimpleName();
protected String[] workoutDays = new String[7];
protected String workoutName;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_workout);
Button mNextButton = (Button) findViewById(R.id.next_button1);
CheckBox satBox = (CheckBox) findViewById(R.id.sat_checkbox);
CheckBox sunBox = (CheckBox) findViewById(R.id.sun_checkbox);
CheckBox monBox = (CheckBox) findViewById(R.id.mon_checkbox);
CheckBox tuesBox = (CheckBox) findViewById(R.id.tues_checkbox);
CheckBox wedBox = (CheckBox) findViewById(R.id.wed_checkbox);
CheckBox thursBox = (CheckBox) findViewById(R.id.thurs_checkbox);
CheckBox friBox = (CheckBox) findViewById(R.id.fri_checkbox);
final EditText mWorkoutName = (EditText) findViewById(R.id.workout_name1);
workoutName = mWorkoutName.getText().toString();
Log.i(TAG, workoutName);
if (satBox.isChecked()) {
workoutDays[0] = new String(satBox.getText().toString());
}
if (sunBox.isChecked()) {
workoutDays[1] = new String(sunBox.getText().toString());
}
if (monBox.isChecked()) {
workoutDays[2] = new String(monBox.getText().toString());
}
if (tuesBox.isChecked()) {
workoutDays[3] = new String(tuesBox.getText().toString());
}
if (wedBox.isChecked()) {
workoutDays[4] = wedBox.getText().toString();
}
if (thursBox.isChecked()) {
workoutDays[5] = satBox.getText().toString();
}
if (friBox.isChecked()) {
workoutDays[6] = friBox.getText().toString();
Log.i(TAG, workoutDays[6]);
}
mNextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.i(TAG, workoutDays.toString());
Intent intent = new Intent(CreateWorkoutActivity.this, WorkoutRoutinesActivity.class);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_NAME, workoutName);
intent.putExtra(WorkoutRoutinesActivity.EXTRA_WORKOUT_DAYS, workoutDays);
Log.i(TAG, workoutDays.toString());
startActivity(intent);
}
});
}
The problem is not in the intent, but in the way you obtain workoutName (this is the null value). You create the activity, set up final EditText mWorkoutName = (EditText) findViewById(R.id.workout_name1); and then immediately ask for the input value through workoutName = mWorkoutName.getText().toString();, but at this time the user still hasn't entered anything. You should put that second line in the listener below (so its activated only after the user presses mNextButton. It's a good idea to put some check after it and send a message to user that they need to fill in that field (if it is indeed necessary).
Looks like the values for workoutName and workoutDays are not filled in initially when the view is created. You should move retrieving the value from the text fields to your onClickListener function.
you checking the CheckBox and EditText in onCreate, absolutely the EditText will be empty and all CheckBox it not checked
i need help please.
I have two activities and a db. All i want to do is when i press a button in activity A, i send the string in my editText to the activity B. In the activity B i try to insert that string in my db and display it in a listview. All works if i start the activity B in the activity A but i wont display the activity B.
Here my code:
Activity A:
public class Example extends Activity {

String InputString;
InputString = MyInputText.getText().toString();
try{
Intent d = new Intent(Example.this, Secondactivity.class);
d.putExtra(ID_EXTRA2, InputString);
//startActivity(d); <----- If i start the secondactivity, that works...
}catch (Exception e){
}
}
};
public boolean onCreateOptionsMenu(Menu menu){
super.onCreateOptionsMenu(menu);

awesome.inflate(R.menu.main_menu, menu);
return true;

startActivity(new Intent("com.example.activities.SECONDACTIVITY"));
return true;
case R.id.menu2:
//something to do
return true;
}
return false;
}
};

public class Secondactivity extends Activity {

}
};

super(Zhistorytranslate.this, c);
}
public void bindView(View row2, Context ctxt, Cursor c) {
NoteHolder2 holder2 = (NoteHolder2)row2.getTag();
holder2.populateFrom2(c, helper2);
}
public View newView(Context ctxt, Cursor c, ViewGroup parent) {

}
void populateFrom2(Cursor c, NoteHelper2 helper2) {
entriText.setText(helper2.getEntri(c));
}
}
If I understood you correctly, you want to send data from A to B without launching B. In this case, you need to forget about Intents and consider a way to store data in your app. My suggestion is to use SharedPreferences.
Here is how you can use it:
In your Activity A, store the String:
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = prefs.edit();
editor.putString("string_id", InputString); //InputString: from the EditText
editor.commit();
In your Activity B, you can get the value by:
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
String data = prefs.getString("string_id", "no id"); //no id: default value
Your question is very difficult to understand, but you seem to want to be able to add the EditText's contents into your database without starting another Activity. Simply do this in your Image's OnClickListener:
public void onClick(View v) {
NoteHelper2 helper2 = new NoteHelper2(this);
helper2.insert(MyInputText.getText().toString());
}
You should also read about Java naming convention.
well i'm having some problem with android. Maybe its simple but i'm pretty new in android world (3, 4 days actually). Well i have an activity whitch runs an asyncTask that stands to reading data from a sensor network. The async Task only executes the function l.read() that by itself is a loop and keep allways "earing" the sensor network and when a new node joins to the sensor network, it tells the UI thread that one more node has joined, and so it has to update the view (witch has just one tab saying that no nodes exists and will now have to have one node available - besides this i even have to load an xml layout file for this tab ) the problem is that, when i preform the function that supostly creates a view and add a tab (that is properly working because when i call it on onCreate it works) the app do not respond anymore, however, Logcat gives me no errors. It look like it works but it is not showing anything.
Please, i dont expect you to read all this code, its just to hel to explain my problem. Its been 2 days and i'm still asking for a solution..

Many thanks in advance
it's weird that your app doesn't crash , since all UI operations should be done on the UI thread . maybe it's because the asynctask's thread has crashed but not the ui thread , and that's why nothing occurs.
anyway , in order to create/update the view within the asyncTask , you can use any of the following , which will post something to the UI thread to do as soon as it can :
use a handler.
use publishProgress.
use runOnUiThread.
It's hard to explain in the title. Basically as far as I can tell the submit button is taking the name and placing it in the array like I want. What I need now is for the Play(done) Button to transfer the user and the data to the next class (which I believe is coded correctly) and I need it to start a game. The game which you will see in the second class (get the data from the previous) I need it to display the names from the names array 1 at a time and randomly assign them a task to do from the tasks array.
Currently the app is force closing after I click the play button. I'm linking both classes cause I'm pretty sure the problem is in the second class. Thanks for your help ahead of time.

champButton.setOnClickListener(new View.OnClickListener()

Thought I should also mention that these buttons on the 2nd page I would like to assign a score to whichever name array person is up and keep track until the final round where it will display the winner. If anyone has any idea how to make that work.
Have you made sure to include the Game activity as an Application Node in your AndroidManifest?
If not, open your manifest to the application tab, on the bottom hit Add, and add an Activity of the name .Game
Without this, that intent never gets received by the other class.
You've already been told that you use non-initialized arrays here: EditText and using buttons to submit them. But also you're trying to get array extra, however you don't put it inside intent. And you're using uninitialized tasks array in Game class.
