How does android write an interface for voting or expressing opinions?

First:

 

 

Place these views in a LinearLayout:

 

Each Item can be implemented as follows:

 

 

Public class KXTagWidget extends TextView {String mTagName =;/** colors */int mBgColor = Color. WHITE; int mPressedBgColor = Color. WHITE; int mTextColor = Color. WHITE; int mPressedTextColor = Color. BLACK; public KXTagWidget (Context context) {super (context); setClickable (true);} public KXTagWidget (Context context, AttributeSet attrs) {super (context, attrs ); setClickable (true);} public KXTagWidget (Context con Text, AttributeSet attrs, int defStyle) {super (context, attrs, defStyle); setClickable (true);} public void setName (String tagName) {if (tagName! = Null) {mTagName = tagName; this. setText (mTagName) ;}} public void setBgColor (int bgColor, int pressedBgColor) {mBgColor = bgColor; mPressedBgColor = pressedBgColor; this. setBackgroundColor (bgColor); // this. set} public int getmPressedBgColor () {return mPressedBgColor;} public void setmPressedBgColor (int mPressedBgColor) {this. mPressedBgColor = mPressedBgColor;} public int getmPressedTextColor () {return mPressedTextColor;} public void setmPressedTextColor (int mPressedTextColor) {this. mPressedTextColor = mPressedTextColor;} public int getmBgColor () {return mBgColor;} public void setmBgColor (int mBgColor) {this. mBgColor = mBgColor;} public int getmTextColor () {return mTextColor;} public void setmTextColor (int mTextColor) {this. mTextColor = mTextColor;} public void setTextColor (int textColor, int pressedTextColor) {mTextColor = textColor; mPressedTextColor = pressedTextColor;} @ Overrideprotected void onDraw (Canvas canvas) {super. onDraw (canvas); // Add the border Paint paint = new Paint (); paint. setColor (this. mBgColor); int width = getWidth (); int height = getHeight (); canvas. drawLine (0, 0, width-1, 0, paint); canvas. drawLine (width-1, 0, width-1, height, paint); canvas. drawLine (width-1, height-1, 0, height-1, paint); canvas. drawLine (0, height-1, 0, 0, paint);} public int getMesuredWidth () {int mesuredWidth = 0; Paint p = this. getPaint (); float textWidth = p. measureText (mTagName); mesuredWidth = (int) textWidth + this. getCompoundPaddingLeft () + this. getCompoundPaddingRight (); return mesuredWidth ;}}

Implementation of Activity:

 

 

Private static final int VOTE_BAR_IMAGE_NUM = 9; private int mVoteBarImage [] = new int [VOTE_BAR_IMAGE_NUM]; private HashMap
 
  
MVoteControlMap = new HashMap
