Android Color Example

Android Multiple Button and Color Example

Actually in This example i am going to explain several topic:

1. Use Of Multiple Button
2. Giving click event via XML File
3. Accessing Color using import android.graphics.Color class
4. Accessing Color property from value>color.xml file

step 1: create an color.xml file in res/values/ folder

    #ff0000

    #0000ff

    #000000

    #ffffff

    #FFD700

    

    

step 2: create an activity_MultiButton.xml in res/layout folder

    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/TableLayout1"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".Button1Activity" >

   

step3: Create MultiButtonActivity class

import android.os.Bundle;

import android.app.Activity;

import android.content.res.Resources;

import android.graphics.Color;

import android.text.Layout;

import android.view.Menu;

import android.view.View;

import android.widget.TableLayout;

public class MultiButtonActivity extends Activity {

TableLayout background;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_button1);

background = (TableLayout)findViewById(R.id.TableLayout1);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.button1, menu);

return true;

}

public void setColor(View v)

{

switch(v.getId())

{

case R.id.button1 :

background.setBackgroundColor(getResources().getColor(R.color.red));

break;

case R.id.button2 :

background.setBackgroundColor(Color.BLUE);

break;

case R.id.button3 :

background.setBackgroundColor(getResources().getColor(R.color.black));

break;

case R.id.button4 :

background.setBackgroundColor(Color.WHITE);

break;

case R.id.button5 :

background.setBackgroundColor(getResources().getColor(R.color.gold));

}

}

}

Output Screen:
