Android: Textview not showing the value set programatically

Question

I want to set the value of textview programatically, everything seems okay by me but dont know why the set value is not appearing

This is the code:

//set the value of a text view
            final TextView textView = (TextView) findViewById(R.id.validityValue);
            textView.setText("30 days");

This is what I have in my xml file

<TextView 
        android:id="@+id/validityValue"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:textSize="12sp"
        android:textColor="#000" />

With the above code, the textview is not showing when the application launched.

Answer 1

Review properly that id is not conflicted..Please be sure that you don't have same id of TextView in two fragments for tab in viewpager If you are using those...

Answer 2

At first Change Your android:textColor .Use This

android:textColor="#000000"

Then

  final TextView textView = (TextView) findViewById(R.id.validityValue);
    textView.setText("30 days");
    String str1 = textView.getText().toString();
    Log.d("++++++",str1);

Then check What Log.d returns .

If Log.d returns properly then post your Total XML .

Answer 3

Add the below code in your xml and run your application. Let me know what happens.

    android:text="New Text"
