How can I display an Integer value in TextView?

When I try, I get an error android.content.res.Resources$NotFoundException: String resource ID

    Six answers, and noone mentions why it doesn't "just work" when you specify an integer value in the setText() method. After a bit looking around I've concluded that the problem is that setText() with an integer value assumes that the integer is actually a resource ID number. – RenniePet Jun 01 '15 at 00:36

    and thats why the app crashes with a weird error `UncaughtException: android.content.res.Resources$NotFoundException` – Faisal Naseer Feb 24 '17 at 10:45

TextView tv = new TextView(this);
tv.setText(String.valueOf(number));

or

tv.setText(""+number);

TextView tv = new TextView(this);
tv.setText("" + 4);

    @BoldijarPaul, `setText(String.valueOf(variable));` sample code provided in [Muhammad Abdullah's answer](https://stackoverflow.com/a/3994387/6398434) doesn't and I can confirm it works pretty well. – JorgeAmVF Apr 18 '18 at 15:21

    @JorgeAmVF both work good, but the 1st one will give you a lint warning. – Boldijar Paul Apr 19 '18 at 06:13

If you want it to display on your layout you should

For example:

activity_layout.XML file

    <TextView
        android:id="@+id/example_tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

On the activity.java file

    final TextView textView = findViewById(R.id.example_tv);
    textView.setText(Integer.toString(yourNumberHere));

In the first line on the XML file you can see: 

android:id="@+id/example_tv"

That's where you get the id to change in the .java file for the findViewById(R.id.example_tv)

Hope I made myself clear, I just went with this explanation because a lot of times people seem to know the ".setText()" method, they just can't change the text in the "UI".

EDIT Since this is a fairly old answer, and Kotlin is the preferred language for Android development, here's its counterpart.

With the same XML layout:

You can either use the findViewbyId() or use Kotlin synthetic properties:

findViewById<TextView>(R.id.example_tv).text = yourNumberHere.toString()

// Or

example_tv?.text = yourNumberHere.toString()

The toString() is from Kotlin's Any object (comparable to the Java Object):

The root of the Kotlin class hierarchy. Every Kotlin class has Any as a superclass.

Consider using String#format with proper format specifications (%d or %f) instead.

int value = 10;

textView.setText(String.format("%d",value));

This will handle fraction separator and locale specific digits properly

Alternative approach:

 TextView tv = new TextView(this);
 tv.setText(Integer.toString(integer));

String s = Integer.toString(10);

Then setText(s)

just found an advance and most currently used method to set string in textView

textView.setText(String.valueOf(YourIntegerNumber));

It might be cleaner for some people to work with an Integer object so you can just call toString() directly on the object:

Integer length = my_text_view.getText().getLength();
counter_text_view.setText( length.toString() );
