分享一个闪耀字体的自定义View

import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.LinearGradient; import android.graphics.Matrix; import android.graphics.Paint; import android.graphics.Shader; import android.util.AttributeSet; import android.widget.TextView; /** * 闪耀字体 */ public class ShiningFontView extends TextView { private int mViewWidth; private Paint mPaint; private LinearGradient mLinearGradient; private Matrix mGradientMatrix; private int mTranslate; public ShiningFontView(Context context) { super(context); } public ShiningFontView(Context context, AttributeSet attrs) { super(context, attrs); } public ShiningFontView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } @Override protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(w, h, oldw, oldh); if (mViewWidth == 0) { mViewWidth = getMeasuredWidth(); if (mViewWidth > 0) { mPaint = getPaint(); mLinearGradient = new LinearGradient(0, 0, mViewWidth, 0, new int[]{Color.BLUE, 0xffffffff, Color.BLUE}, null, Shader.TileMode.CLAMP); mPaint.setShader(mLinearGradient); mGradientMatrix = new Matrix(); } } } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); if (mGradientMatrix != null) { mTranslate += mViewWidth / 5; if (mTranslate > 2 * mViewWidth) { mTranslate = -mViewWidth; } mGradientMatrix.setTranslate(mTranslate, 0); mLinearGradient.setLocalMatrix(mGradientMatrix); postInvalidateDelayed(100); } } }

使用方式如下

<com.hz56pt.huipaotui.view.ShiningFontView//包裹起来就行 android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="@dimen/margin_10" android:layout_toRightOf="@id/iv_tips1_icon" android:text="@string/tips1" />

效果图如下
