Hope this helps You need to add the dependency com.android.support:palette-v7:21.0.+ to your build.gradle file.
See https://developer.android.com/tools/support-library/features.html#v7-palette for reference.

Which class is implementing ContextWrapper's methods in Android?

Which class is implementing ContextWrapper's methods in Android?

this will help I finally found it out myself with the helpful tip from nicholas.hausschild, to just to run the debugger.
Unfortunatly this seems to be the only way, to find that out, because it's implemented in a Class called ContextImpl, which is package-readable (though not documented). You have to install Eclipse source-code plugin (which seems to be a little buggy to install, if you had downloaded and linked the Android-SDK to eclipse already) to see the sources.

Any of those help Ok I am really a little confused with your code. I would do something like this. If abc is my custom view in package com.test in my activity layout file xyz.xml
code :
<com.test.abc
android:id="@+id/myview"
<!-- You can modify the values below the way you want -->
android:layout_width="300dp"
android:layout_height="300dp"
android:layout_gravity="center"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"/>
public class abc extends ImageView{

  private OnclickxitemListener listener;

    public interface OnclickxitemListener
    {
      public String nil = "nilkash";
      public void onclickxtitem();
    }


    public void setOnxitemSelectedListener(OnclickxitemListener l )
    {
      listener = l;

    }

     public abc(Context context, AttributeSet attrs)
    {
      super(context, attrs);
      initialize();

    }

    public void initialize()
    {

      this.setImageResource(R.drawable.*name of the image saved in drawable*);


        setOnClickListener(new OnClickListener()
        {

         @Override
     public void onClick(View arg0) 
         {
          // TODO Auto-generated method stub
    notifyListener();
         }

        });
     }

     private void notifyListener()
     {
            if (null!=listener)
            listener.onclickxtitem();
     }
}
public class xyz extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.xyz);

        abc myview = (abc)findViewById(R.id.myview);
        myview.setOnxitemSelectedListener(new abc.OnclickxitemListener()
             {
                @Override
                public void onclickxtitem()
                 {


                 }
              });

    }

help you fix your problem I am generating gnuplot scripts with Python. Some of the Gnuplot scripts create graphs (with only a few points on them) with a color variation. I have to reuse the same colors for other graphs. I have discovered that it is possible to use the command , On a Unix system you can start gnuplot with
code :
gnuplot 2>/dev/null
Android - Implementing Parcelable Inner Class

Android - Implementing Parcelable Inner Class


By : Bill Chen

wish helps you You simply need to implement the Parcelable interface for each inner class (ListEntity, SysEntity, ...), so all classes and classes they contain implement Parcelable.
Then you add the class to the parcel using
code :
public final void writeParcelable (Parcelable p, int parcelableFlags)
public class SampleParcelable implements Parcelable {
    public static class InnerClass implements Parcelable {
        private String mInnerString;
        private long mInnerLong;

        // parcelable interface
        @Override
        public int describeContents() {
            return 0;
        }

        @Override
        public void writeToParcel(Parcel dest, int flags) {
            dest.writeString(mInnerString);
            dest.writeLong(mInnerLong);
        }

        public static final Creator<InnerClass> CREATOR = new Creator<InnerClass>() {
            public InnerClass createFromParcel(Parcel in) {
                return new InnerClass(in);
            }

            public InnerClass[] newArray(int size) {
                return new InnerClass[size];
            }
        };

        private InnerClass(Parcel in) {
            mInnerString = in.readString();
            mInnerLong = in.readLong();
        }
    }

    private String mString;
    private long mLong;
    private InnerClass mInnerClass;

    // parcelable interface
    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(mString);
        dest.writeLong(mLong);
        dest.writeParcelable(mInnerClass, flags);
    }

    public static final Creator<SampleParcelable> CREATOR = new Creator<SampleParcelable>() {
        public SampleParcelable createFromParcel(Parcel in) {
            return new SampleParcelable(in);
        }

        public SampleParcelable[] newArray(int size) {
            return new SampleParcelable[size];
        }
    };

    private SampleParcelable(Parcel in) {
        mString = in.readString();
        mLong = in.readLong();
        mInnerClass = in.readParcelable(InnerClass.class.getClassLoader());
    }
}

may help you . How can I add transparency value to a palette's swatch? Like I am adding the color(swatch.getRGB()) to a linear layout, It shows solid color. And I don't want to use alpha as it will make other items in layout transparent too. , Use android support utility class:
