本文实例为大家分享了闪耀字体效果的具体代码，供大家参考，具体内容如下

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

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
