文字两种颜色渐变

//自定义 布局中引用即可

public class TwoTextView extends TextView {
    private LinearGradient mLinearGradient;
    private Paint mPaint;
    private int mViewWidth = 0;
    private Rect mTextBound = new Rect();

    public TwoTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        mViewWidth = getMeasuredWidth();
        mPaint = getPaint();
        String mTipText = getText().toString();
        mPaint.getTextBounds(mTipText, 0, mTipText.length(), mTextBound);
        mLinearGradient = new LinearGradient(0, 0, mViewWidth, 0,
                new int[]{Color.parseColor("#58BEFF"),
                        Color.parseColor("#4463FF")},
                null, Shader.TileMode.REPEAT);
        mPaint.setShader(mLinearGradient);
        canvas.drawText(mTipText, getMeasuredWidth() / 2 - mTextBound.width() / 2, getMeasuredHeight() / 2 + mTextBound.height() / 2, mPaint);
    }
}
