Toast.makeText(this, text, Toast.LENGTH_LONG).show();
Intent intent = new Intent(this, YOUR_ACTIVITY_NAME.class);
intent.putExtra("DATA", text);
startActivity(intent);
// Or else you can do whatever you want to do here with that text
}
}
Then in your other activity
String data = getIntent().getStringExtra("DATA");
YOUR_TEXTVIEW_NAME.setText(data);

This is basics of Android so before answering I suggest you to go
through basic tutorials before posting on Stackoberflow.
Now,
Here is how you can access the items from your string_array.
String[] chapters= getResources().getStringArray(R.array.chapters);
Now,here is pseudo code that might help you.
btn1.setOnClickListener(
your_text_view.setText(chapters[0])
)
//Here 0 means your first item, likewise you can access items by their index in
array

About Correct or Wrong answer

I want a test for 3-4 years old childs. I want if they click different apple , true count must plus one. And if they click one of same aplles false count must plus one. And click any apple the question and apples are must change.

Thank you so much

You are comparing drawables. which never matches.
Change your if(CONDITION) to following:
if(secenek1.getDrawable().getConstantState().equals(getResources().getDrawable(dogruCevap).getConstantState())).
same way for other two cases.

change the colors of different buttons randomly at a specified time

I have 4 different buttons. I want to change the background of the buttons at a fixed time (say 1 sec i.e. one button changes its color for one sec then retains its previous color and then other button does the same and so on) in certain random pattern, and then the user will repeat this pattern. However I am unable to change the background of the buttons randomly. I know that a timer or handler will b used but I have no idea ho to use it. Can anyone post a example program that shows how to change the background of buttons randomly?

}
}`

You could try something like this:
Button[] changingButtons = new Button[4];
changingButtons[0] = (Button)findViewById(R.id.button1_id);
changingButtons[1] = (Button)findViewById(R.id.button2_id);
changingButtons[2] = (Button)findViewById(R.id.button3_id);
changingButtons[3] = (Button)findViewById(R.id.button4_id);
You can then access the corresponding button in the array and change the background colour using changingButtons[<desired index>].setBackgroundResource(<color resource>)
To retain the previous color, you can use ColorDrawable previousBackground = (ColorDrawable)changingButtons[<desired index>].getBackground();
Then, for the "set time" part, use a timer, and do the colour switching in the TimerTask.
If you wish to use a TimerTask would look something like this inside the method calling it:
timer = new Timer();
timer.schedule(new MyTask(buttonNumber), numMilliseconds);
And then MyTask would be an extension class of TimeTask
class MyTask extends TimerTask
{
private int buttonId;
public MyTask(int buttonId)
{
super();
this.buttonId = buttonId;
}
public void run()
{
//Do your button alterations here
}
}
Here's a sample I made using the above code on Ideone
Hopefully this points you in the right direction!
For more information, check out these: Changing the background color programmatically, Getting the background color, Java Timer documentation

You can use Collections.shuffle(colorList);
List<String> colorList=new ArrayList<>();
colorList.add("#108E44");
colorList.add("#000000ff");
colorList.add("#108E44");
for() {
giveMeButtons(i).setBackgorundColor(Color.parseColor(colorList.get(i)));
}
And you must make other method. It will return random View button.

Probably da error in the code is that you never defined an id "add" - you have #+id/TextView01 in the xml "page" (you mean file - and you must tell us which file) but no #+id/add

but when i run it to emulator,and i choose 1 option in spinner and click the button , the TextView doesn't show up the word from spinner which i choose
(for example, i choose "senin" at spinner, and click the button, but the text "senin" doesn't appear in the TextView )
i check DDMS and there are no error.....
is the code wrong?
can you help me please which one is wrong?
Thank anyway....

I think you don't set the selection listener on your spinner.
But actually you can just retrieve the spinner's selected position with getSelectedItemPosition in the click handler of your button:
Try this:
public void clickHandler(View view) {
switch (view.getId()) {
case R.id.btnSubmit:
textView1.setText(nama_hari[spinner1.getSelectedItemPosition()]);
break;
}
}
