android 自定义view xml设置数组

自定义参数中，设置数组内容，数组值，数组文字颜色，数组背景颜色，数组icon id

<包名.CommonLinearTextLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="@dimen/margin_13"
    app:common_linear_state="@{item.status}"
    app:common_linear_state_array_attr="@array/business_state"
    app:common_linear_state_array_value="@array/business_state_value"
    app:common_linear_state_array_text_color="@array/business_state_textColor"
    app:common_linear_state_array_bg_color="@array/business_state_bgColor"
    app:common_linear_state_array_icon_id="@array/business_state_icon"
    app:common_linear_title_text="状态:"
    app:common_linear_title_text_minWidth="@dimen/margin_100" />

res values目录下新增文件arrays.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="business_state">
        <item>已锁定</item>
        <item>待审核</item>
        <item>正常</item>
    </string-array>
    <integer-array name="business_state_value">
        <item>-1</item>
        <item>0</item>
        <item>1</item>
    </integer-array>
    <string-array name="business_state_textColor">
        <item>common_color_5b6068</item>
        <item>common_color_E95E13</item>
        <item>common_color_67C23A</item>
    </string-array>
    <string-array name="business_state_bgColor">
        <item>common_color_10_5b6068</item>
        <item>common_color_10_E95E13</item>
        <item>common_color_10_67C23A</item>
    </string-array>
    <string-array name="business_state_icon">
        <item>icon_locked</item>
        <item>icon_audit</item>
        <item>icon_normal</item>
    </string-array>
</resources>

注意：这里的颜色和图片，直接使用string-array，并且item定义的值，为文件名，或者颜色定义的名称

如何获取数组值

private int[] initColorOrDrawable(int arrayIconIdArray, int defaultId, String defType) {
    String[] icons = getResources().getStringArray(arrayIconIdArray);
    int[] idArrays = new int[icons.length];
    for (int i = 0; i < icons.length; i++) {
        int resId = getResources().getIdentifier(icons[i], defType, getPackageName());
        if (resId != 0) {
            idArrays[i] = resId;
        } else {
            idArrays[i] = defaultId;
        }
    }
    return idArrays;
}

//获取字体颜色
int arrayColorResourceId = typedArray.getResourceId(R.styleable.common_linear_styleable_common_linear_state_array_text_color, 0);
if (arrayColorResourceId != 0) {
    stateTextColorIdArray = initColorOrDrawable(arrayColorResourceId, R.color.common_color_67C23A, "color");
} else {
    // 如果属性没有设置，设置默认值
    stateTextColorIdArray = new int[]{R.color.common_color_67C23A, R.color.common_color_FB5352};
}

//获取图片
int arrayIconIdArray = typedArray.getResourceId(R.styleable.common_linear_styleable_common_linear_state_array_icon_id, 0);
if (arrayIconIdArray != 0) {
    stateIconIdArray = initColorOrDrawable(arrayIconIdArray, R.drawable.icon_close, "drawable");
} else {
    // 如果属性没有设置，设置默认值
    stateIconIdArray = new int[]{R.drawable.icon_normal, R.drawable.icon_close};
}

//获取Drawable
private Drawable getImg(int state) {
    for (int i = 0; i < stateArray.size(); i++) {
        if (stateArray.get(i) == state) {
            if (i < imgIdArray.size()) {
                return getResources().getDrawable(imgIdArray.get(i));
            }
            break;
        }
    }
    if (defaultImgId != 0) {
        return getResources().getDrawable(defaultImgId);
    }
    return new ColorDrawable(Color.TRANSPARENT);
}

//设置图片显示
Drawable img = tv.getImg(stateValue);
tv.setImage(img);
