Android实现EditText文本颜色渐变

飞哥语录：亲疏随缘，爱恨随意。

先上效果图

刚开始想着先是设置textColor属性就可以了，然后写了个一个带渐变的shap感觉不好使，于是乎就自定义解决，代码如下

import android.content.Context; import android.graphics.Canvas; import android.graphics.LinearGradient; import android.graphics.Paint; import android.graphics.Rect; import android.graphics.Shader; import android.util.AttributeSet; import android.widget.EditText; public class MyEditText extends EditText { public MyEditText(Context context) { this(context, null); } public MyEditText(Context context, AttributeSet attrs) { this(context, attrs, 0); } public MyEditText(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } private Paint mPaint; private int mViewHeight = 0; private Rect mTextBound = new Rect(); private LinearGradient mLinearGradient; @Override protected void onDraw(Canvas canvas) { mViewHeight = getMeasuredHeight(); mPaint = getPaint(); String mText = getText().toString(); mPaint.getTextBounds(mText, 0, mText.length(), mTextBound); mLinearGradient = new LinearGradient(0, 0, 0, mViewHeight, new int[]{0xFF8EDA4D, 0xFF4EB855}, null, Shader.TileMode.REPEAT); mPaint.setShader(mLinearGradient); canvas.drawText(mText, getMeasuredWidth() / 2 - mTextBound.width() / 2, getMeasuredHeight() / 2 + mTextBound.height() / 2, mPaint); } }

我这里实现的是上下的渐变色，当然每个人的需求都不一样，有的要实现左右渐变色，只要在这句中设置其属性即可

mLinearGradient = new LinearGradient(0, 0, 0, mViewHeight,new int[]{0xFF8EDA4D, 0xFF4EB855}, null, Shader.TileMode.REPEAT)

好了，今天的分享就到这里，如有问题，欢迎在下方留言评论。
