Android - TextViews not showing up in ListView - java

I'm having an issue to where none of my TextViews are showing up in the ListView. I'm not sure whether it is an issue with the layout or the java class itself. There are two images here, one of the application running after data had been entered into the database and one of what it is supposed to look like.
Layout for each row of data in ListView
Fragment for the ListView (Delete Button appears but not the TextViews)

I don't believe the issue is with database showing the data because some of the TextViews in the ListView don't even use the data from inside the database.

your row_layout.xml file textview in set textcolor:
<TextView
android:layout_width="123dp"
android:layout_height="wrap_content"
android:id="#+id/resultTeamNumber"
android:text="Here Number"
android:textSize="18dp"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:textColor="#android:color/black"
/>

It is theme issue on your end,probably textcolor set to white in your theme change these
<item name="android:textColorPrimary">#color/white</item>
<item name="android:textColorSecondary">#color/white</item>
change it to black

set your adapter upon listview in the last..............

The issue is when I don't put any value into the firstEditText or secondEditText or both of them and click on any button then the app crashes and a pop up shows "myapp keeps stopping".
I cannot get the text and am unsure of why the app keeps crashing.

you have defined your Edit texts in the first activity with id's named
edtPhone
edtMessage
but there was no edtPhone or edtMessage in your xml.
this issue also repeats in your second activity
you have defined txtPhone and txtMessage
but again there are no such ids in your second activity XML.
keep in mind that these might not be the whole problem as you didn't post any log for the errors. but if there were anything else, ask and we'll help you

I want an image to rotate around its center, but my method is not working, it's clearly rotated around a different pivot point. I'm new to Android development, so you may find some serious mistakes in my code. Also, if I rotate the screen, the image is rotated back to its initial rotation.

This is my Activity
RelativeLayout custom_RelativeLayout = (RelativeLayout)findViewById(R.id.actionbar_relativelayout);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM );
getSupportActionBar().setCustomView(R.layout.custom_actionbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayShowCustomEnabled(true);
getSupportActionBar().setDisplayUseLogoEnabled(false);
getSupportActionBar().setDisplayShowHomeEnabled(false);
getSupportActionBar().setBackgroundDrawable(
getApplicationContext().getResources().getDrawable(
R.drawable.drawable_actionbar_back));
getSupportActionBar().setCustomView(R.layout.custom_actionbar);
I want to its occupy whole space of action bar but it does not occupy i also read many answers on stackoverflow but didn't work.
1) I want match parent space in action bar
Edit This is my main Avtivity

If you want to get the height of native action bar then use ?android:attr/actionBarSize in XML.
Now your XML will look like:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"

so im really new to android programming(and java) and im trying to do basic stuff.I followed tutorial on the internet but I cant manage to do what I want.I have spinners with edittext, and a button.When I click the button, I want the selected items in the spinners and numbers in the edittext to go in another textview(load a new page with a big textview).So far I did this:
(Mainactivity.java)
package com.example.spinnertest;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Button;
import android.widget.Spinner;
import android.widget.TextView;
public class MainActivity extends Activity {
Spinner s1,s2,s3,s4;
TextView txt2;
Button button1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
s1 = (Spinner) findViewById(R.id.spinner1);
s2= (Spinner) findViewById(R.id.spinner2);
s3 = (Spinner) findViewById(R.id.spinner3);
txt2 = (TextView) findViewById(R.id.textView2);
/////////CODE PART FOR TESTING ONLY,NO LINK WITH MY QUESTION/////
s1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
String val = s1.getSelectedItem().toString();
txt2.setText(val);
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
s3.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
String val = s3.getSelectedItem().toString();
txt2.setText(val);
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
s2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
String val = s2.getSelectedItem().toString();
txt2.setText(val);
}
//////////////////END OF TESTING CODE PART///////////
// OnClickListener of Button
button.setOnClickListener(new OnClickListener() { ///theres few errors here?
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// Getting values of text and spinners
//selectedDay = daySpinner.getSelectedItem().toString(); //this code doesnt fit the way I define my spinners;see below
//selectedMonth = monthSpinner.getSelectedItem().toString(); //this code doesnt fit the way I define my spinners;see below
//text = editText.getText().toString(); //this code doesnt fit the way I define my spinners;see below
// Creating an Intent to open new Activity(Screen) and sending
// the details
Intent intent = new Intent(MainActivity.this, Affichage.class);
// intent.putExtra("day", selectedDay);//this code doesnt fit the way I define my spinners;see below
//intent.putExtra("month", selectedMonth);//this code doesnt fit the way I define my spinners;see below
//intent.putExtra("text", text); //this code doesnt fit the way I define my spinners;see below
startActivity(intent);
}
});
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
}
};}}
seconde java file activity:
package com.example.spinnertest;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.Spinner;
import android.widget.TextView;
public class Display extends ActionBarActivity {
TextView textView;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
Spinner s1;
setContentView(R.layout.activity_display);
textView = (TextView) findViewById(R.id.disp);
s1 = (Spinner) findViewById(R.id.spinner1);
Intent intent = getIntent();
if(intent!=null)
{
String val = s1.getSelectedItem().toString();
textView.setText(val);
//String month = intent.getStringExtra("month"); //example from the internet;doesnt fit my code
//String text = intent.getStringExtra("text"); //example from the internet,doesnt fit my code
}
else
{
textView.setText("Intent is null");
}
}}
layout of the second page with the textview:
<?xml version="1.0" encoding="utf-8"?>

content of my spinner are defined in array.xml(in values) like this:
<resources>
<array name="spin1">
<item>item1</item>
<item>item2</item>
<item>item3</item>
</array>
<array name="Type">
<item> A</item>
<item> B</item>
<item>c</item>
<item>d</item>
</array>
<array name="Production">
<item>motorbike</item>
</array>
</resources>
So I want the selected items of my spinners + edittext to go in a textview on a new page, and I dont know how to do that, But I have a good start I think?
thank you

You should be fine sending the data over an intent with myIntent.setExtra("Data", data); as you have above. Why do you define your spinners to listen to every change when all you want is the final value? You can use mySpinner.getSelectedItem().toString(); instead. Can you please elaborate on the doesn't fit my code please? (I would comment this but i don't have 50 rep)

I am new to android. I am trying to make simple unit converter. The layout contains EditText for input, two spinners (to and from), an ImageButton and EditText to display answer.
I want to add values to spinners and when these values are selected i want to perform action.
My xml code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>
My java code:
package com.easy.convert;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.Spinner;
import android.widget.TextView;
public class BitsBytes extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.bitsbytes);
ImageButton ib = (ImageButton) findViewById(R.id.convertButton);
ib.setOnClickListener(new View.OnClickListener() {
EditText etValue = (EditText) findViewById(R.id.inputvalue);
Spinner spBitsBytesFrom = (Spinner) findViewById(R.id.SpinnerFrom);
Spinner spBitsBytesTo = (Spinner) findViewById(R.id.SpinnerTo);
String txtFromSpinner = spBitsBytesFrom.getSelectedItem().toString();
String txtToSpinner = spBitsBytesTo.getSelectedItem().toString();
TextView Answer = (TextView) findViewById(R.id.answer);
public void onClick(View v)
{
if (txtFromSpinner.equals("Bits") && txtToSpinner.equals("Bytes"))
{
Double value = Double.parseDouble(etValue.getText().toString());
Double answer = (double) 0;
answer = value/8;
String stringAnswer = Double.toString(answer);
Answer.setText(stringAnswer);
}
}
});
}
}
I am filling the spinners using string array. I am not able to figure out whats wrong in my code because there is no error in logcat.

Change this,
(txtFromSpinner.equals("Bits") && txtToSpinner.equals("Bytes"))
to
if((txtFromSpinner.getSelectedItem().toString().equals("Bits")) && (txtToSpinner.getSelectedItem().toString().equals("Bytes")))
this will get the text from the item selected in the spinner.
