View 的构造方法的调用顺序

view 构造方法的调用顺序：

:boom:

public View(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

:boom:

public View(Context context, AttributeSet attrs, int defStyleAttr) {
    this(context, attrs, defStyleAttr, 0);
}

:boom:

public View(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
    this(context);
     ...
}

:boom: ####最终都要调用 > View(Context context)

public View(Context context) {
    mContext = context;
    mResources = context != null ? context.getResources() : null;
    mViewFlags = SOUND_EFFECTS_ENABLED | HAPTIC_FEEDBACK_ENABLED;
    // Set some flags defaults
    mPrivateFlags2 =
            (LAYOUT_DIRECTI
    ...
}
