    textView.setText(versionName);

    //Initialize the sample
    ((LinearLayout) findViewById(R.id.LinearLayout)).setBackgroundColor(mColor);
    float hsv[] = newfloat[3];
    Color.colorToHSV(mColor, hsv);
    if (UberColorPickerDialog.isGray(mColor))
        hsv[1] = 0;
    if (hsv[2] < .5)
        ((TextView) findViewById(R.id.sample)).setTextColor(Color.WHITE);
    else ((TextView) findViewById(R.id.sample)).setTextColor(Color.BLACK);

    //Set up the buttonsButtonbutton= (Button) findViewById(R.id.colorPickerWithTitle);
    button.setOnClickListener(this);

    button = (Button) findViewById(R.id.colorPickerWithToast);
    button.setOnClickListener(this);
}

protectedvoidonPause() {
    super.onPause();
}

protectedvoidonResume() {
    super.onResume();
}

publicbooleanonCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);

    returntrue;
}

publicbooleanonPrepareOptionsMenu(Menu menu) {
    super.onPrepareOptionsMenu(menu);

    returntrue;
}

publicbooleanonOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    }

    returnsuper.onOptionsItemSelected(item);
}

publicvoidonClick(View v) {
    if (v.getId() == R.id.colorPickerWithTitle)
        newUberColorPickerDialog(this, this, mColor, true).show();
    if (v.getId() == R.id.colorPickerWithToast)
        newUberColorPickerDialog(this, this, mColor, false).show();
}

publicvoidcolorChanged(int color) {
    ((LinearLayout) findViewById(R.id.LinearLayout)).setBackgroundColor(mColor=color);

    float hsv[] = newfloat[3];
    Color.colorToHSV(mColor, hsv);
    //if (UberColorPickerDialog.isGray(mColor))//  hsv[1] = 0;if (hsv[2] < .5)
        ((TextView) findViewById(R.id.sample)).setTextColor(Color.WHITE);
    else ((TextView) findViewById(R.id.sample)).setTextColor(Color.BLACK);
   }
  }

And use the color picker class
