'Android: change background color View onClick Button

How I can change the background color to a View this under a button when I click the button? I've tried a selector does not work because the View not change the color. What is the problem?

This is my code:

XML

    ...
          <View
            android:id="@+id/viewPlanos2"
            android:layout_width="match_parent"
            android:layout_height="3dp"
            android:layout_gravity="center" />

        <Button
            android:id="@+id/button"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:layout_weight="1"
            android:background="@color/transparente"
            android:drawableTop="@drawable/buttonimage"
            android:gravity="center"
            android:paddingTop="50dp" />

        <View
            android:id="@+id/viewPlanos1"
            android:layout_width="match_parent"
            android:layout_height="3dp"
            android:layout_gravity="center" />
 ...

JAVA

View linea2 = (View)findViewById(R.id.viewPlanos2);
linea2.setBackgroundColor(getResources().getColor(R.drawable.linea_verde));

linea_verde

<item android:state_pressed="true"><shape>
        <gradient android:angle="90" android:endColor="@color/azul" android:startColor="@color/azulOscuro" />
    </shape></item>
<item android:state_focused="true"><shape>
        <gradient android:angle="90" android:endColor="@color/azul" android:startColor="@color/azulOscuro" />
    </shape></item>
<item><shape>
        <solid android:color="@color/rojo" />
    </shape></item>

EDIT:

I have tried:

public void onClick(View v) {

    if(v == botonMetro) {

        linea2.setBackgroundResource(R.drawable.linea_verde);
                    and

        linea2.setBackgroundColor(getResources().getColor(R.drawable.linea_verde));
    }
}

But the code not work

androidviewcolorsbackground


Solution 1:[1]

You are wrongly using drawable use this one one

 view.setBackgroundResource(R.drawable.linea_verde)

Solution 2:[2]

as you say change the background color to a View this under a button when I click the button

do like this

 button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {

                  // change color of your view here  
           linea2.setBackgroundColor(getResources().getColor(R.drawable.linea_verde));

          }
    });

setBackgroundColor() is for colors only, but it seems your using a state list drawable. If you are sure you want to use a different color depending on the Button's state, set the state list drawable using this code:

view.setBackgroundDrawable(R.drawable.linea_verde);

Otherwise, just set the background color using

view.setBackgroundColor(getResources().getColor(R.drawable.yourcolor);

But in this case, use a click listener, and also make sure to actually use a color resource, e.g.:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="opaque_red">#f00</color>
    <color name="translucent_red">#80ff0000</color>
</resources>

You can also do like this.

android:background="@drawable/linea_verde"

Solution 5:[5]

If you would like to apply default background of selected item you could use background attribute with android ?attr.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="?attr/selectableItemBackground" />

selectableItemBackground attribute will use proper drawable according to Android version. On pre-lollipop it will use solid background, but on lollipop devices the ripple effect will be used.

Code from: com.android.support/appcompat-v7/23.0.0/res/values/values.xml

<item name="selectableItemBackground">@drawable/abc_item_background_holo_dark</item>

public void onClick(View v) {
    int id = v.getId();
    if(id == R.id.button) {
        linea2.setBackgroundResource(R.drawable.linea_verde);
    }
}

I think you were comparing the view the wrong way. I just happened to stumble to this question and since it is not marked as answered, this might help others.

Create two separate files for your shapes and change the background of your view after button click:

private boolean isPressed = false;    

public void onClick(View v) {
    if(v == botonMetro) {
        if(isPressed){
           linea2.setBackgroundResource(R.drawable.pressed_shape);       
        } else{
           linea2.setBackgroundResource(R.drawable.un_pressed_shape);       
        }
        isPressed = !isPressed;
    }
}
