I have a layout with multiple TextView's. When the user clicks one I check if the the TextView has a background. If it has a background I remove it, else if it doesn't I set it.

Here is an example of my code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/linear"
    android:orientation="vertical"
    android:background="@drawable/selector">

    <TextView
        android:id="@+id/text_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:textAppearance="@android:style/TextAppearance.Medium"/>
</RelativeLayout>

So my question is, how do I check if the TextView already has a background set?

Update

if( textView.getBackground() == null) {
                    Log.i("here", "null");
                    textView.setBackgroundResource(R.drawable.draw_cross);

                 }

                 if(textView.getBackground() != null) {
                     Log.i("here", "not null");

                     textView.setBackground(null);

                 }

You can achieve this with the following code:

Java:

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView textView = findViewById(R.id.text_view);
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (hasBackground(v)) {
                    v.setBackground(null);
                } else {
                    v.setBackgroundResource(R.drawable.draw_cross);
                }
            }
        });
    }

    private boolean hasBackground(View v) {
        return v.getBackground() != null;
    }
}

else

            count = count+2;
        }
        else if(count%2 != 0)
        {
            tv.setBackgroundResource(0);
        }
    }
