如何在textView中設置不同的寬度

Question

我已經創建了一個自定義ListView，其中我添加了兩個TextView,TextView之一顯示日期，其他TextView顯示在該特定日期輸入的權重。現在我想要的是在第二個TextView顯示權重，文本視圖的寬度設置爲用戶輸入的權重。我寫的代碼顯示了一些問題。意味着當用戶輸入重量70和75時，寬度TextView顯示相同的尺寸。爲什麼會這樣。請任何人都幫我解決這個問題。對於列表活動

Screnn拍攝

Answer 1

的左/右頁邊距它們是60dps每個可能的問題。你的空間花費120dps。 http://android-developers.blogspot.com/2011/07/new-tools-for-managing-screen-sizes.html表示手機的屏幕尺寸爲320dp寬。

此外，我不確定CycleManager是做什麼的，但如果不這樣做，可能會定義最大值，您應該使用設備的屏幕寬度和相應的縮放比例。

最後，我想這是不相關的，但你使用wrap_content爲listview。你不覺得讓fill_parent更合適嗎？

Answer 2

OK @Anshuman這是一個屏幕實體的問題。 70和75是相同的大小，因爲你已經超出了你對該視圖的空間。嘗試更改該藍色標記的比例。也許像這樣的東西會給你更多的空間（只是玩弄shrinkScaler變量，直到你得到你需要的大小，以適應你想要的所有重量

double shrinkScaler = .75; 
holder.txt_weight_display.setMinWidth((int)(borderwidth * shrinkScaler));
