android Textview颜色渐变

1.在代码中设置：

TextView mText = (TextView) findViewById(R.id.text);LinearGradient mLinearGradient = new LinearGradient(0, 0, 0, mText.getPaint().getTextSize(), Color.WHITE, Color.BLACK, Shader.TileMode.CLAMP);mText.getPaint().setShader(mLinearGradient);

2.自定义控件：

package com.leigo.demo.view;import android.content.Context;import android.graphics.Color;import android.graphics.LinearGradient;import android.graphics.Shader;import android.util.AttributeSet;import android.widget.TextView;/** * Created by Administrator on 2014/9/9. */public class GradientTextView extends TextView {    public GradientTextView(Context context) {        super(context);    }    public GradientTextView(Context context,                            AttributeSet attrs) {        super(context, attrs);    }    public GradientTextView(Context context,                            AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);    }    @Override    protected void onLayout(boolean changed,                            int left, int top, int right, int bottom) {        super.onLayout(changed, left, top, right, bottom);        if (changed) {            getPaint().setShader(new LinearGradient(                    0, 0, 0, getHeight(),                    Color.WHITE, Color.BLACK,                    Shader.TileMode.CLAMP));        }    }}
