How to I know parent padding from custom view?

I create a custom view and added it to layout: ``` <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:custom="http://schemas.android.com/apk/res/com.eleks.customview" android:padding="20dp" android:layout_width="match_parent" android:layout_height="match_parent" > <com.eleks.customview.CView android:id="@+id/circle1" android:layout_width="wrap_content" android:layout_height="wrap_content" custom:textSize="@dimen/circle_text_size" custom:text="@string/circle_default_text" custom:radius="@dimen/circle_radius" custom:textColor="@color/circle_text" custom:textBackground="@color/circle_background" /> </LinearLayout> ``` I implement onMeasure in custom view and set width and height. But my view ignores parent padding (20dp). See the picture: public class CView extends View { private static final String TAG = "CView"; ``` // default value private static final int DEFAULT_RADIUS = 30; private static final int DEFAULT_TEXT_SIZE = 12; private static final int DEFAULT_TEXT_COLOR = Color.BLACK; private static final int DEFAULT_BACKGROUND = Color.GRAY; private static final int DEFAULT_WIDTH = DEFAULT_RADIUS * 2; private static final int DEFAULT_HEIGHT = DEFAULT_RADIUS * 2; // variables private Paint mBackgroundPaint = null; private Paint mTextPaint = null; private float mCircleX = 0; private float mCircleY = 0; private float mTextX = 0; private float mTextY = 0; private int mWidth = DEFAULT_WIDTH; private int mHeight = DEFAULT_HEIGHT; // attrs private int mTextColor = DEFAULT_TEXT_COLOR; private int mBackground = DEFAULT_BACKGROUND; private float mRadius = DEFAULT_RADIUS; private String mText = null; private float mTextSize = 0; public CView(Context context) { super(context); Log.d(TAG, "init view"); init(null); } public CView(Context context, AttributeSet attrs) { super(context, attrs); Log.d(TAG, "init view"); init(attrs); } private void init(AttributeSet attrs) { if (attrs != null) { TypedArray a = getContext().getTheme().obtainStyledAttributes(attrs, R.styleable.CircleButton, 0, 0); try { mTextColor = a.getColor(R.styleable.CircleButton_textColor, DEFAULT_TEXT_COLOR); mBackground = a.getColor(R.styleable.CircleButton_textBackground, DEFAULT_BACKGROUND); mRadius = a.getDimension(R.styleable.CircleButton_radius, DEFAULT_RADIUS); mText = a.getString(R.styleable.CircleButton_text); mTextSize = a.getDimensionPixelOffset(R.styleable.CircleButton_textSize, DEFAULT_TEXT_SIZE); } finally { a.recycle(); } } mBackgroundPaint = new Paint(); mBackgroundPaint.setColor(mBackground); this.setMinimumHeight((int) mRadius * 2); this.setMinimumWidth((int) mRadius * 2); } private void initLayoutParams() { LayoutParams params = this.getLayoutParams(); params.width = mWidth + getLeft(); params.height = mHeight + getTop(); Log.d(TAG, "params| width: " + mWidth + " height: " + mHeight); } private void initText() { mTextPaint = new Paint(); mTextPaint.setColor(mTextColor); mTextPaint.setTextSize(mTextSize); Rect textRect = new Rect(); if (mText == null) { mText = ""; } mTextPaint.getTextBounds(mText, 0, mText.length(), textRect); mTextX = mCircleX - (((Math.abs(textRect.right) - Math.abs(textRect.left))) / 2); mTextY = mRadius + ((Math.abs(textRect.top) - (Math.abs(textRect.bottom))) / 2); Log.d(TAG, "text| x: " + mTextX + " y: " + mTextY); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); Log.d(TAG, "init onDraw"); if (canvas != null) { canvas.drawCircle(mCircleX, mCircleY, mRadius, mBackgroundPaint); // canvas.drawText(mText, mTextX, mTextY, mTextPaint); } } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { // super.onMeasure(widthMeasureSpec, heightMeasureSpec); Log.d(TAG, "init onMeasure"); setWidth(MeasureSpec.getMode(widthMeasureSpec), MeasureSpec.getSize(widthMeasureSpec)); setHeight(MeasureSpec.getMode(heightMeasureSpec), MeasureSpec.getSize(heightMeasureSpec)); mCircleX = getLeft() - getPaddingLeft() + mRadius; mCircleY = getTop() - getPaddingTop() + mRadius; fixedSize(); Log.d(TAG, "circle| x: " + mCircleX + " y: " + mCircleY); this.setMeasuredDimension(mWidth, mHeight); // initText(); } private void fixedSize() { if (mWidth > mHeight) { mHeight = mWidth; } else if (mHeight > mWidth) { mWidth = mHeight; } } private void setWidth(final int modeWidth, final int width) { switch (modeWidth) { case MeasureSpec.AT_MOST: Log.d(TAG, "width mode is AT_MOST"); if (mRadius > 0) { mWidth = (int) (mRadius * 2) + getPaddingLeft() + getPaddingRight(); } else { mWidth = DEFAULT_WIDTH; } mWidth = Math.min(mWidth, width); break; case MeasureSpec.EXACTLY: Log.d(TAG, "width mode is EXACTLY"); break; case MeasureSpec.UNSPECIFIED: default: Log.d(TAG, "width mode is UNSPECIFIED"); mWidth = DEFAULT_WIDTH; break; } } private void setHeight(final int modeHeight, final int height) { switch (modeHeight) { case MeasureSpec.AT_MOST: Log.d(TAG, "height mode is AT_MOST"); if (mRadius > 0) { mHeight = (int) (mRadius * 2) + getPaddingTop() + getPaddingBottom(); } else { mHeight = DEFAULT_HEIGHT; } mHeight = Math.min(mHeight, height); break; case MeasureSpec.EXACTLY: Log.d(TAG, "height mode is EXACTLY"); break; case MeasureSpec.UNSPECIFIED: default: Log.d(TAG, "height mode is UNSPECIFIED"); mHeight = DEFAULT_HEIGHT; break; } } @Override protected void onLayout(boolean changed, int left, int top, int right, int bottom) { // super.onLayout(changed, left, top, right, bottom); Log.d(TAG, "init onLayout"); initLayoutParams(); } ``` How can I get parent's padding?
