问题描述
我有问题,在安卓aplication组织布局。我动态创建按钮并将其添加这个code到我的布局:
I have problem with organizing layout in android aplication. I'm dynamically creating buttons and adding them with this code to my layout:
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i < NO_NUMBERS; i++){
Button btn = new Button(this);
btn = (Button) layoutInflater.inflate(R.layout.button, null);
btn.setId(2000+i);
Integer randomNumber = sort.getNumbersCopy()[i];
btn.setText(randomNumber.toString());
btn.setOnClickListener((OnClickListener) this);
buttonList.addView(btn);
list.add(btn);
}
我将它添加到的LinearLayout:
I'm adding it to the LinearLayout:
<LinearLayout
android:id="@+id/buttonlist"
android:layout_alignParentLeft="true"
android:layout_marginTop="185dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:orientation="horizontal"
android:gravity="center_horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</LinearLayout>
我就是导入此的.xml在那里我定义按键布局:
and i'm importing this .xml where i'm defining button layout:
<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:textSize="26dp"
android:textStyle ="bold"
android:textColor="#ffffff"
android:background="@drawable/button"
android:layout_marginLeft="8px"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"/>
嗯,布局最终总是这样的:
Well, layout always ends up like this:
,而不是像这样(按钮之间甚至SPCE,方形按钮):
Instead of something like this (even spce between buttons, square buttons):
要总结:我有:
- 描述XML按钮
- 动态产生N个按钮
- 描述按钮添加属性,动态创建的那些
- 在组织布局,因此它可以均匀地分配按钮buttonList与艾德里安之间的空格
推荐答案
记住,安卓布局_ *
属性的LayoutParams
。他们争论的父母和会影响家长会的这一观点进行布局。你指定 layout_margin
在你的按钮属性,但他们得到的忽略。这里的原因:
Remember, android:layout_*
attributes are LayoutParams
. They are arguments to the parent and affect how the parent will perform layout on that view. You're specifying layout_margin
attributes on your buttons, but they're getting ignored. Here's why:
由于的LayoutParams
是特定父视图类型,您需要提供正确的父类的一个实例,当您使用 LayoutInflater膨胀布局
或者布局_
在布局的顶层视图属性将被丢弃。 (充气器将不知道是什么类型的的LayoutParams
的生成。)
Since LayoutParams
are specific to the parent view type, you need to supply an instance of the correct parent type when you inflate layouts using a LayoutInflater
or else layout_
attributes on the top-level view in the layout will be dropped. (The inflater would have no idea what type of LayoutParams
to generate.)
由于 buttonList
是你的目标父为按钮的观点,改变你的膨胀
行这样的:
Since buttonList
is your intended parent for the button views, change your inflate
line to this:
btn = (Button) layoutInflater.inflate(R.layout.button, buttonList, false);
