旋转ImageView和TextView的效果实现
如图ImageView和TextView组成布局同时旋转。，求实现效果。
经过几天研究终于实现如图效果。代码如下，给需要的人吧。还涉及到部分背景图的效果。
public class IconViewGroup extends ViewGroup{ TextView mTextView; ImageView mImageView;//显示对应的icon private Context mContext; /** * 命名区域 */ private final String namespace = "http://com.oppo.examples"; /** * 保存创建旋转角度 */ private float mRotateDegrees; /** * 保存创建背景图片的ID */ private int mBackGroudDrawableId; /** * 利用图片ID加载图片 */ private Drawable mBackGroudDrawable; /** * 原始图片所需宽、高 */ private int mBackGroundWidth; private int mBackGroundHeight; private View view; private static final int ICON_WIDTH=46;//显示数字的TextView的长宽 private static final int ICON_HEIGHT=46; private static final int TEXT_WIDTH=46;//显示数字的TextView的长宽 private static final int TEXT_HEIGHT=260; public IconViewGroup(Context context) { super(context); // TODO Auto-generated constructor stub } public IconViewGroup(Context context, AttributeSet attrs) { super(context, attrs); init(context); mContext = context; mBackGroudDrawableId=attrs.getAttributeResourceValue(namespace, "background", R.drawable.item_on); mBackGroudDrawable = context.getResources().getDrawable( mBackGroudDrawableId); mRotateDegrees=attrs.getAttributeFloatValue(namespace, "rotateDegrees",30.0f); } private void init(Context context) { // TODO Auto-generated method stub mTextView=new MyTextView(context); mTextView.setTextSize(28); mTextView.setGravity(Gravity.CENTER_VERTICAL);// mTextView.setBackgroundColor(0xFFFFFF00); mTextView.setText(R.string.app_name); mTextView.setTextColor(0xF0FFFFFF); mImageView=new ImageView(context); mImageView.setBackgroundResource(R.drawable.icon); this.addView(mTextView); this.addView(mImageView); } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { // TODO Auto-generated method stub int ivWidth=mImageView.getMeasuredWidth(); int ivHeight=mImageView.getMeasuredHeight(); int tvWidth=mTextView.getMeasuredWidth(); int tvHeight=mTextView.getMeasuredHeight(); mTextView.measure(r - l, b - t); mTextView.layout(5+ivWidth+10, getHeight()-tvHeight-5,getWidth(),getHeight()-5); mImageView.measure(r - l, b - t); mImageView.layout(5, 5+getHeight()-ivHeight, ivWidth,getHeight()); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { // TODO Auto-generated method stub super.onMeasure(widthMeasureSpec, heightMeasureSpec); /** * 设定View显示区域 */ mBackGroundHeight=mBackGroudDrawable.getIntrinsicHeight(); mBackGroundWidth=mBackGroudDrawable.getIntrinsicWidth(); if (mRotateDegrees==90.0f) { setMeasuredDimension(mBackGroundHeight, mBackGroundWidth); } else { setMeasuredDimension(mBackGroundWidth, mBackGroundHeight); } } @Override protected void dispatchDraw(Canvas canvas) { // TODO Auto-generated method stub canvas.rotate(mRotateDegrees); mBackGroudDrawable.setBounds(0, 0, mBackGroundWidth, mBackGroundHeight); mBackGroudDrawable.draw(canvas); super.dispatchDraw(canvas); } }
