問(wèn)題描述

我完全無(wú)法在 TableRow 中獲取固定寬度的 EditText 小部件.我正在嘗試以相同的寬度(大約 20dip)并排放置兩個(gè) EditText，但無(wú)論我嘗試設(shè)置哪個(gè)屬性并將第一個(gè) EditText 設(shè)置為很長(zhǎng)并且顯然無(wú)法調(diào)整大小.

I'm completely stuck trying to get fixed width EditText widgets in a TableRow. I am attempting to place two EditText side by side with equal width (about 20dip) but no matter which property I try and set the first EditText is way to long and apparently cannot be resized.

非常感謝:

<TableRow 
  android:layout_height="wrap_content"
  android:baselineAligned="false" 
  android:id="@+id/tableRow3" 
  android:gravity="center"
  android:stretchColumns="1" 
  android:layout_width="match_parent">
  <TextView 
    android:id="@+id/textView6" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="1" 
    android:paddingLeft="36dip">
  </TextView>
  <EditText
    android:layout_height="wrap_content" 
    android:id="@+id/editText2" 
    android:inputType="number" 
    android:layout_width="20dip">
  </EditText>
  <EditText 
    android:layout_height="wrap_content" 
    android:id="@+id/editText1" 
    android:inputType="number"
    android:layout_width="wrap_content">
    <requestFocus></requestFocus>
  </EditText>
</TableRow>

推薦答案

我不知道 TableLayout 是不是最好的方法，它可能很麻煩，除非你顯示大量數(shù)據(jù)并且需要使用它.

I don't know that a TableLayout is the best way to do this, it can be cumbersome unless you're displaying large amounts of data and need to use it.

我發(fā)現(xiàn)確保表單對(duì)象按照我想要的方式分配長(zhǎng)度的最佳方法之一是使用權(quán)重而不是顯式聲明寬度.

One of the best ways I've found to ensure that form objects have length distributed the way I want them is by using weight rather than explicitly declaring width.

嘗試以下方法:

<LinearLayout ... android:orientation="horizontal" ... 
android:layout_width="match_parent" android:layout_height="wrap_content"
<TextView ... android:layout_width="0dp" ... android:layout_weight="50" />
<TextView ... android:layout_width="0dp" ... android:layout_weight="50" />
</LinearLayout>

確保將布局寬度聲明為 0，這將使布局填充到權(quán)重.

Make sure to declare the layout width as 0, this will let the layout fill to the weight.

這應(yīng)該會(huì)在屏幕上創(chuàng)建兩個(gè)相鄰的 TextView，它們都占據(jù)了 50% 的屏幕.你可以玩不同的百分比.您還可以使用 LinearLayout 作為占位符，其權(quán)重為您希望放置的任何 %.

This should create two TextViews next to each other on the screen, both filling 50% of the screen. You can play with different percentages. You can also use a LinearLayout as a placeholder with a weight of whatever % you would like to place hold.

確保您的權(quán)重"加起來(lái)為 100，以確保視圖看起來(lái)完全符合您的要求.這不是必需的，但知道它將占據(jù)屏幕寬度的百分比是一個(gè)很好的約定.

Make sure that your "weights" add up to 100 in order to ensure the view will look exactly as you want it to. It's not necessary, but it's a good convention to know what % of the screen width it will take up.
