【100分】急需帮助，关于获取资源文件的问题

Question

有一个 style文件
文件中的部分代码如下<style name="style_text_title">
<item name="android:textSize">25px</item>
<item name="android:textColor">#ec9237</item>
<item name="android:layout_width">fill_parent</item>
<item name="android:layout_height">wrap_content</item>
</style>TypedArray arr = context.getResources().obtainTypedArray(resId);
然后开始遍历
for(int i=0; i<arr.length(); i++){
key = arr.getString(i);//??? 不知道如何获取key 就是item的name属性
value = arr.getText(i).toString();
Log.i(TAG, key + "---" + value);
Log.i(TAG, arr.toString());
}
我捣鼓了好久。也没办法实现， 求助有设么方法可以获取指定资源ID的xml定义（注意最好用系统内置的方法， 原因是效率高）比如说
obj.getBySomeMethod(R.id.style_text_title) // 我可以获取到整个 xml的定义（如顶部xml）

Answer 1

应该是这个方法吧
obtainStyledAttributes();看官方TextView源代码 很长不全贴了
 TypedArray a =
            context.obtainStyledAttributes(
                attrs, com.android.internal.R.styleable.TextView, defStyle, 0);....
...
..
.
 /*
         * Look the appearance up without checking first if it exists because
         * almost every TextView has one and it greatly simplifies the logic
         * to be able to parse the appearance first and then let specific tags
         * for this View override it.
         */
        TypedArray appearance = null;
        int ap = a.getResourceId(com.android.internal.R.styleable.TextView_textAppearance, -1);
        if (ap != -1) {
            appearance = context.obtainStyledAttributes(ap,
                                com.android.internal.R.styleable.
                                TextAppearance);
        }
        if (appearance != null) {
            int n = appearance.getIndexCount();
            for (int i = 0; i < n; i++) {
                int attr = appearance.getIndex(i);                switch (attr) {
                case com.android.internal.R.styleable.TextAppearance_textColorHighlight:
                    textColorHighlight = appearance.getColor(attr, textColorHighlight);
                    break;                case com.android.internal.R.styleable.TextAppearance_textColor:
                    textColor = appearance.getColorStateList(attr);
                    break;                case com.android.internal.R.styleable.TextAppearance_textColorHint:
                    textColorHint = appearance.getColorStateList(attr);
                    break;                case com.android.internal.R.styleable.TextAppearance_textColorLink:
                    textColorLink = appearance.getColorStateList(attr);
                    break;                case com.android.internal.R.styleable.TextAppearance_textSize:
                    textSize = appearance.getDimensionPixelSize(attr, textSize);
                    break;                case com.android.internal.R.styleable.TextAppearance_typeface:
                    typefaceIndex = appearance.getInt(attr, -1);
                    break;                case com.android.internal.R.styleable.TextAppearance_textStyle:
                    styleIndex = appearance.getInt(attr, -1);
                    break;
                }
            }            appearance.recycle();
        }

obtainStyledAttributes  这样子获取的还 是一个   TypedArray 都一样啊
