会帮助那些想要完全改变Drawable颜色的人吗

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/ic_memory"
    android:backgroundTint="@color/lime" />

根据isWorking字段更改可绘制颜色的简短示例。

我的形状xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="@android:color/holo_blue_bright" />
    <corners android:radius="30dp" />
    <size
        android:height="15dp"
        android:width="15dp" />
</shape>

我的改变方法:

private Drawable getColoredDrawable(int drawableResId, boolean isworking) {
    Drawable d = getResources().getDrawable(R.drawable.shape);
    ColorFilter filter = new LightingColorFilter(
            isworking ? Color.GREEN : Color.RED,
            isworking ? Color.GREEN : Color.RED);
    d.setColorFilter(filter);
    return d;
}

用法示例:

text1.setCompoundDrawablesWithIntrinsicBounds(getColoredDrawable(R.drawable.shape, isworking()), null, null, null);

当你使用一个库来为你做这件事时，这是非常非常简单的。 试试这个库

你可以这样调用:

Icon.on(holderView).color(R.color.your_color).icon(R.mipmap.your_icon).put();

我可以用下面的代码做到这一点，这是从一个活动(布局是一个非常简单的，只包含一个ImageView，并没有张贴在这里)。

private static final int[] FROM_COLOR = new int[]{49, 179, 110};
private static final int THRESHOLD = 3;

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test_colors);

    ImageView iv = (ImageView) findViewById(R.id.img);
    Drawable d = getResources().getDrawable(RES);
    iv.setImageDrawable(adjust(d));
}

private Drawable adjust(Drawable d)
{
    int to = Color.RED;

    //Need to copy to ensure that the bitmap is mutable.
    Bitmap src = ((BitmapDrawable) d).getBitmap();
    Bitmap bitmap = src.copy(Bitmap.Config.ARGB_8888, true);
    for(int x = 0;x < bitmap.getWidth();x++)
        for(int y = 0;y < bitmap.getHeight();y++)
            if(match(bitmap.getPixel(x, y))) 
                bitmap.setPixel(x, y, to);

    return new BitmapDrawable(bitmap);
}

private boolean match(int pixel)
{
    //There may be a better way to match, but I wanted to do a comparison ignoring
    //transparency, so I couldn't just do a direct integer compare.
    return Math.abs(Color.red(pixel) - FROM_COLOR[0]) < THRESHOLD &&
        Math.abs(Color.green(pixel) - FROM_COLOR[1]) < THRESHOLD &&
        Math.abs(Color.blue(pixel) - FROM_COLOR[2]) < THRESHOLD;
}

试试这段代码:

ImageView lineColorCode = (ImageView)convertView.findViewById(R.id.line_color_code);
int color = Color.parseColor("#AE6118"); //The color u want             
lineColorCode.setColorFilter(color);
