我動態在我的代碼使用更改視圖的寬度寬度相同 - 第一個按鈕比第二個寬。我知道這是因爲一個是浮點數,一個是十進制數,但我怎樣才能使它們都成爲小數點,或者我應該只對浮點數進行反覆試驗?我的params.weight只接受浮點值。layout_weight在浮點和十進制
編輯: 這裏是我的XML代碼:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:layout_width="wrap_content"

<!--Let's set the height of the linearlayout below to 0dp. Apparently it's less work on resources,
as otherwise we would be drawing it twice, because the size is also set dynamically-->

that's what gravity does-->

如果想法是讓它們匹配'LayoutParams',爲什麼不只是檢索xml中指定的'ImageButton'的'LayoutParams',然後將其設置爲'ImageButton'的'LayoutParams'你想動態?像這樣: 'buttonTwo.setLayoutParams(buttonOne.getLayoutParams());' –
這是一個有趣的想法。回家時會看看它。 – CHarris
讓我知道它是否有效,如果有效,我會將其添加爲答案。 –
