Android实现EditText文本颜色渐变

先上效果图
这里写图片描述

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)
