【问题描述】:
如何访问自定义视图的 android:layout_width 和 android:layout_height 值?
示例 xml:
<com.example.CustomButton
android:id="@+id/btn"
android:layout_width="150dp"
android:layout_height="70dp" />
在自定义按钮中:
@Override
protected void onMeasure(int widthSpec, int heightSpec) {
int measuredWidth = MeasureSpec.getSize(widthSpec);
int measuredHeight = MeasureSpec.getSize(heightSpec);
// How can we measure based on android:layout_width, android:layout_height?
// Currently this implementation measures off the parent's values
setMeasuredDimension(measuredWidth, measuredHeight);
}
