Set android:baselineAligned="false" on this element for better performance
如果LinearLayout被用於嵌套的layout空間計算,它的android:baselineAligned屬性應該設置成false,以加速layout計算
android:baselineAligned="false"
This LinearLayout layout or its RelativeLayout parent is useless;
多余的Linearlayout或者RelativeLayout
刪除即可
This tag and its children can be replaced by one <TextView/> and a compound drawable
有時候我們可能會用image+textview組合,但其實image是沒必要的,textview提供了一個屬性來給它設置image
android:drawable="@drawable/resource"
Use a layout_height of 0dip instead of wrap_content for better performance
當在一個linearlayout布局中為一個控件設置weight屬性時,這個組件會默認填充剩余空間
去掉weight屬性或者修改wrap_content為0dp
Buttons in button bars should be borderless
原因未知
style="?android:attr/buttonBarButtonStyle"
