TINT简单使用（转来记录）

1.在xml中设置tint和tintMode实现对图片的着色，它通过修改图形的Alpha遮罩来修改图像的颜色，从而达到重新着色的目的

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:src="@mipmap/icon_head" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:src="@mipmap/icon_head"
        //此处为设置新颜色
        android:tint="#FF4081" />
</LinearLayout>

2.利用DrawableCompat对图片进行动态颜色渲染

package com.per.tintdome;

import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.support.v4.content.ContextCompat;
import android.support.v4.graphics.drawable.DrawableCompat;
import android.widget.ImageView;

public class MainActivity extends Activity {
    private ImageView imageView1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        imageView1 = (ImageView) findViewById(R.id.image1);
        //利用ContextCompat工具类获取drawable图片资源
        Drawable drawable = ContextCompat.getDrawable(this, R.mipmap.icon_head);
        //简单的使用tint改变drawable颜色
        Drawable drawable1 = tintDrawable(drawable,ContextCompat.getColor(this, R.color.colorAccent));
        imageView1.setImageDrawable(drawable1);
    }

    public static Drawable tintDrawable(Drawable drawable, int colors) {
        final Drawable wrappedDrawable = DrawableCompat.wrap(drawable).mutate();
        DrawableCompat.setTint(wrappedDrawable, colors);
        return wrappedDrawable;
    }
}
