I have this code:
void sendMessage(){
EditText messageText = (EditText) findViewById(R.id.editText3);
String messageString = messageText.getText().toString();
LinearLayout chatLayout = (LinearLayout) findViewById(R.id.chatView);
TextView chatMessage = new TextView(this);
chatMessage.setText(messageString);
chatLayout.addView(chatMessage);
messageText.setText("");
scrollChatDown();
/*
int arraySize = messages.size();
messages.set(arraySize + 1, chatMessage);
*/
}
When I call the function sendMessage(); by a button, it gives an empty TextView, when I call the function again, it gives me a TextView with the text.
Output
I did what jiotman said but it didn't work, now I have this
void sendMessage(){
TextView chatMessage = new TextView(this);
EditText messageText = (EditText) findViewById(R.id.editText3);
String messageString = messageText.getText().toString();
LinearLayout chatLayout = (LinearLayout) findViewById(R.id.chatView);
chatLayout.addView(chatMessage);
chatMessage.setText(messageString);
messageText.setText("");
scrollChatDown();
/*
int arraySize = messages.size();
messages.set(arraySize + 1, chatMessage);
*/
}
As I see, you`r trying to implement kind of list with item population.
I`d use bubble list view for this purpose, here is a simple tutorials how to do it.

In main activity I have button which onClick method creates EditText every time when user clicks this button. I wanted to pass user input from each EditText to TextView into another activity. But TextView shows user input only from last EditText. My code may look strange, because I tried to solve problem on my own. How can I show user input from each created EditText? I am new to programming. Thank you in advance.
Java code
EditText code
int i=1;
int numberOfCreated = 2;
public void buttonCreate(View view){ // button onClick method
for(i=1;i<numberOfCreated;i++){
LinearLayout createdEditText1Layout=findViewById(R.id.createdEditText1Layout);
editText1 = new EditText(this);
LinearLayout.LayoutParams paramsForEditText1 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
editText1.setLayoutParams(paramsForEditText1);
editText1.setInputType(InputType.TYPE_CLASS_TEXT);
editText1.setHint(R.string.editText1Hint);
editText1.setTextSize(16);
createdEditText1Layout.addView(editText1);
}
}
Intent to pass string to second activity
public void openResult() {
String productName = editText1.getText().toString();
Intent intent2 = new Intent(this, ResultActivity.class);
intent2.putExtra("product", productName);
startActivity(intent2);
}
public void buttonResultClick(View view){
openResult();
}
Second activity
int i=1;
int numberOfButtons = 2;
for(i=1;i<numberOfButtons;i++) {
LinearLayout layoutForProductName = findViewById(R.id.layoutForProductName);
TextView productNameTextView = new TextView(this);
LinearLayout.LayoutParams layoutParamsForProductNameTextView = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
productNameTextView.setLayoutParams(layoutParamsForProductNameTextView);
productNameTextView.setTextSize(40);
String productName = getIntent().getStringExtra("product");
productNameTextView.setText(productName);
layoutForProductName.addView(productNameTextView);
}
From what I can tell it's because you're adding only one String productName
You can solve this by passing a String Array aka String[]
public void openResult() {
ArrayList<String> productNames = new ArrayList<String>();
for(int y=0; y < createdEditText1Layout.getChildCount(); y++)
{
if((View)layout.getChildAt(y) instanceof TextView){
String productName = editText1.getText().toString();
productNames.add(productName);
}
}
Intent intent2 = new Intent(this, ResultActivity.class);
intent2.putStringArrayListExtra("product", productNames);
startActivity(intent2);
}
And then in the second Activity you would recalled like
int i=1;
int numberOfButtons = 2;
for(i=1;i<numberOfButtons;i++) {
LinearLayout layoutForProductName = findViewById(R.id.layoutForProductName);
TextView productNameTextView = new TextView(this);
LinearLayout.LayoutParams layoutParamsForProductNameTextView = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
productNameTextView.setLayoutParams(layoutParamsForProductNameTextView);
productNameTextView.setTextSize(40);
String productName = getIntent().getExtras().getStringArrayList("product").get(i);
productNameTextView.setText(productName);
layoutForProductName.addView(productNameTextView);
}
I try solve this but I don't know what I'm doing wrong, has passed 7 days for trying a lot of things, I need help solve it please and I think the mistake is on my created class.
I have 4 players with 4 text view and 4 other text view for the score of the players. Also I have made a new other 4 textviews for the place1, place2, place3, place4. What I want to do is that I need to sort scores and display them in place1, place2, place3, place4 along with the name of that player who has that score.
What I did until now is that I created my class into the main activity above the onCreate section
public class MainActivity extends AppCompatActivity {
//my created class
class JucatorScor {
public String Name;
public int Scor;
public JucatorScor (String sName, int iScor) {
this.Name = sName;
this.Scor = iScor;
}
}
//begin oncreate
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
//end oncreate
}
And I also have a button, when I click it, read my values from the text view name of players, score of players and after sorting the array display place1, place2, place3, place4 like this:
//begin button click
public void sorteazaCLICK (View view) {
//initialization place1, place2, place3, place4 where i will put the sorting value
TextView varPozitia1 = (TextView) findViewById(R.id.text_loc1);
TextView varPozitia2 = (TextView) findViewById(R.id.text_loc2);
TextView varPozitia3 = (TextView) findViewById(R.id.text_loc3);
TextView varPozitia4 = (TextView) findViewById(R.id.text_loc4);
//initialization name of players
TextView varNumeJucator1 = (TextView) findViewById(R.id.text_numeJuc1);
String sNameJuc1;
sNameJuc1 = varNumeJucator1.getText().toString();
TextView varNumeJucator2 = (TextView) findViewById(R.id.text_numeJuc2);
String sNameJuc2;
sNameJuc2 = varNumeJucator1.getText().toString();
TextView varNumeJucator3 = (TextView) findViewById(R.id.text_numeJuc3);
String sNameJuc3;
sNameJuc3 = varNumeJucator1.getText().toString();
TextView varNumeJucator4 = (TextView) findViewById(R.id.text_numeJuc4);
String sNameJuc4;
sNameJuc4 = varNumeJucator1.getText().toString();
//initialization scores
TextView varScorJucator1 = (TextView) findViewById(R.id.text_scorJuc1);
String t1;
t1 = varScorJucator1.getText().toString();
TextView varScorJucator2 = (TextView) findViewById(R.id.text_scorJuc2);
String t2;
t2 = varScorJucator2.getText().toString();
TextView varScorJucator3 = (TextView) findViewById(R.id.text_scorJuc3);
String t3;
t3 = varScorJucator1.getText().toString();
TextView varScorJucator4 = (TextView) findViewById(R.id.text_scorJuc4);
String t4;
t4 = varScorJucator1.getText().toString();
//transform the values from text view scores into integer
int iScorJuc1;
iScorJuc1 = Integer.parseInt(t1);
int iScorJuc2;
iScorJuc2 = Integer.parseInt(t2);
int iScorJuc3;
iScorJuc3 = Integer.parseInt(t3);
int iScorJuc4;
iScorJuc4 = Integer.parseInt(t4);
ArrayList<JucatorScor> arrJucatorScor = new ArrayList<>(4);
//building manually the array list
arrJucatorScor.add(new JucatorScor(sNameJuc1, iScorJuc1)); //position 0
arrJucatorScor.add(new JucatorScor(sNameJuc2, iScorJuc2)); //position 1
arrJucatorScor.add(new JucatorScor(sNameJuc3, iScorJuc3)); //position 2
arrJucatorScor.add(new JucatorScor(sNameJuc4, iScorJuc4)); //position 3
Collections.sort(arrJucatorScor, new Comparator<JucatorScor>() {
//sorting my object array depending on scores
#Override
public int compare(JucatorScor o1, JucatorScor o2) {
return Integer.valueOf(o1.Scor).compareTo(o2.Scor);
}
});
//here display them from bigger to smaller according to eatch place1, place2, place3, place4
varPozitia1.setText(String.valueOf(arrJucatorScor.get(3)));
varPozitia2.setText(String.valueOf(arrJucatorScor.get(2)));
varPozitia3.setText(String.valueOf(arrJucatorScor.get(1)));
varPozitia4.setText(String.valueOf(arrJucatorScor.get(0)));
} //end button click
The problem is that when I click the button don't put on place1, place2, place3, place4 the name and the score sorted... just appear some thing like in this photo:
Here you use the toString() method of JucatorScor to render the objects :
varPozitia1.setText(String.valueOf(arrJucatorScor.get(3)));
varPozitia2.setText(String.valueOf(arrJucatorScor.get(2)));
varPozitia3.setText(String.valueOf(arrJucatorScor.get(1)));
varPozitia4.setText(String.valueOf(arrJucatorScor.get(0)));
What you see in your screen is a default implementation toString() provided by a base class.
Either you implement toString() with the wished text
Or the other solution is to perform the rendering in a helper method and that also sets the suitable String in the TextView:
public set renderTopJucatorScor(JucatorScor jucatorScor, int ranking, TextView varPozitia){
varPozitia.setText("Loc" + ranking + " = " + jucatorScor.getName() + jucatorScor.getScore());
}
Then you can call the helper method like that :
renderTopJucatorScor(varPozitia1, arrJucatorScor.get(3), 1);
renderTopJucatorScor(varPozitia2, arrJucatorScor.get(2), 2);
renderTopJucatorScor(varPozitia3, arrJucatorScor.get(1), 3);
renderTopJucatorScor(varPozitia4, arrJucatorScor.get(0), 4);
After discovering ( with the help of user "davidxxx" ), some mistakes into my initialization of textviews, finnaly i have managed to solve the problem. Also i added into my created class a method: toString.
The correct solution is this:
//my created class
class JucatorScor {
public String Name;
public int Scor;
public JucatorScor (String sName, int iScor) {
this.Name = sName;
this.Scor = iScor;
}
//this is the toString added to diplay name and score
#Override
public String toString() {
return Name + " " + Scor;
}
}
and the exectution code from the button click
//begin button click
public void sorteazaCLICK(View view) {
//initialization of textvies for place1 to place 4
TextView varPozitia1 = (TextView) findViewById(R.id.text_loc1);
TextView varPozitia2 = (TextView) findViewById(R.id.text_loc2);
TextView varPozitia3 = (TextView) findViewById(R.id.text_loc3);
TextView varPozitia4 = (TextView) findViewById(R.id.text_loc4);
//initialization for name of players
TextView varNumeJucator1 = (TextView) findViewById(R.id.text_numeJuc1);
String sNameJuc1;
sNameJuc1 = varNumeJucator1.getText().toString();
TextView varNumeJucator2 = (TextView) findViewById(R.id.text_numeJuc2);
String sNameJuc2;
sNameJuc2 = varNumeJucator2.getText().toString();
TextView varNumeJucator3 = (TextView) findViewById(R.id.text_numeJuc3);
String sNameJuc3;
sNameJuc3 = varNumeJucator3.getText().toString();
TextView varNumeJucator4 = (TextView) findViewById(R.id.text_numeJuc4);
String sNameJuc4;
sNameJuc4 = varNumeJucator4.getText().toString();
//initialization of scores
TextView varScorJucator1 = (TextView) findViewById(R.id.text_scorJuc1);
String t1;
t1 = varScorJucator1.getText().toString();
TextView varScorJucator2 = (TextView) findViewById(R.id.text_scorJuc2);
String t2;
t2 = varScorJucator2.getText().toString();
TextView varScorJucator3 = (TextView) findViewById(R.id.text_scorJuc3);
String t3;
t3 = varScorJucator3.getText().toString();
TextView varScorJucator4 = (TextView) findViewById(R.id.text_scorJuc4);
String t4;
t4 = varScorJucator4.getText().toString();
//transformation scores into integer values
int iScorJuc1;
iScorJuc1 = Integer.parseInt(t1);
int iScorJuc2;
iScorJuc2 = Integer.parseInt(t2);
int iScorJuc3;
iScorJuc3 = Integer.parseInt(t3);
int iScorJuc4;
iScorJuc4 = Integer.parseInt(t4);
ArrayList<JucatorScor> arrJucatorScor = new ArrayList<>(4);
//manually construct of the object array list
arrJucatorScor.add(new JucatorScor(sNameJuc1, iScorJuc1)); //position 0
arrJucatorScor.add(new JucatorScor(sNameJuc2, iScorJuc2)); //position 1
arrJucatorScor.add(new JucatorScor(sNameJuc3, iScorJuc3)); //position 2
arrJucatorScor.add(new JucatorScor(sNameJuc4, iScorJuc4)); //position 3
Collections.sort(arrJucatorScor, new Comparator<JucatorScor>() {
//the sort of the object list by their scores
#Override
public int compare(JucatorScor o1, JucatorScor o2) {
return Integer.valueOf(o1.Scor).compareTo(o2.Scor);
}
});
//here are displayed in the position place1 to place4 from bigger score to smaller score
varPozitia1.setText(String.valueOf(arrJucatorScor.get(3)));
varPozitia2.setText(String.valueOf(arrJucatorScor.get(2)));
varPozitia3.setText(String.valueOf(arrJucatorScor.get(1)));
varPozitia4.setText(String.valueOf(arrJucatorScor.get(0)));
}//end button click
Thanks very much for the help.

Here is my code for creating textviews dynamically.
and i am successful in this.
Now i want to add grid view or listview beneath every text view like the following image :
The same way i want to show text view and display grid or list view on click and this all should be made on bases of arry1 named array's length.
All i want is to create grid or list view dynamically.
I have an ArrayList in which the input of dynamically added EditTexts are referenced. I iterate the ArrayList so that I can get all the values of the EditTexts and add them together. However, I do have one non-dynamically added EditText that is already laid out in my layout.xml.
The problem is that whenever I click my Calculate Button and the only EditText on the screen is the already laid out EditText and it has an input of 1 or any other number, my Calculate Button shows the total input as 0. Whenever I add 1 or more editTexts dynamically, the total input includes the already laid out EditText after I click the Calculate Button.
I need to get the correct total input even if the only input is the non-dynamic editText.

I think you need to take a look at where your adding the tempText2 editText to your list. Check that it isn't as a result of adding the dynamic editTexts.
Look at where you add the following
allEd.add(tempText2);
allEd.add(editText2);
It could be that your only adding the tempText2 as a result of adding a dynamic field. As such when you don't add a dynamic field the arraylist will be empty. resulting in 0. When you do add a dynamic field this will result in the calculation working.
Difficult to say this is it without more code.
I think that maybe u dont initilized value editText2, and u try to add null object to list, but I really cant say anything without any source code.
