在自定義view中獲取android layout_width等屬性值

這裡以獲取layout_width和layout_height為例
1,新建attr檔案
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="album">
<attr name="android:layout_width"/>
<attr name="android:layout_height"/>
</declare-styleable>
</resources>
2,在view建構函式中獲取屬性值:
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.album, defStyleAttr, 0); try { int width = a.getLayoutDimension(R.styleable.album_android_layout_width, -1); int height = a.getLayoutDimension(R.styleable.album_android_layout_height, -2); Log.d(TAG, "AlbumView: " + width + " " + height); } finally { a.recycle(); }
