问题描述
我正在尝试创建一个包含按钮的网格布局,但是默认情况下,这些按钮之间有一个空格,我不需要. .xml文件如下所示:
I'm trying to create a grid layout containing buttons but by default there is a space between these buttons and I don't need that. The .xml file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center">
<HorizontalScrollView android:id="@+id/HorizontalScrollView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center">
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gridLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center">
</GridLayout>
</HorizontalScrollView>
</ScrollView>
我在其中创建按钮并将其添加到网格布局的代码:
The code where I create the buttons and add it to the grid layout:
for (int rowCounter = 0; rowCounter < DIMENSION; rowCounter++)
for (int columnCounter = 0; columnCounter < DIMENSION; columnCounter++) {
Button b = new Button(this);
b.setText(" ");
GridLayout.LayoutParams params = new GridLayout.LayoutParams();
params.setMargins(0, 0, 0, 0);
b.setLayoutParams(params);
gridLayout.addView(b);
}
以下是其外观的图片:
推荐答案
Android默认按钮具有一些填充.
如果您不需要该空间,则需要为按钮创建一个自定义背景.
Android default button have some padding.
If you don't want that space, you need create a custom backgroud for your buttons.
这是一个示例:
button_dark_gradient.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" >
<shape>
<gradient
android:startColor="#00000000"
android:centerColor="#FFFFFF"
android:endColor="#00000000"
android:angle="270" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
<shape>
<gradient
android:startColor="#00CFCCCE"
android:centerColor="#FFFFFF"
android:endColor="#00BAB8B9"
android:angle="270" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#00CFCCCE"
android:centerColor="#FFFFFF"
android:endColor="#00BAB8B9"
android:angle="270" />
</shape>
</item>
</selector>
将按钮的背景设置为此可绘制对象.
Set the backgroud of your buttons to this drawable.
b.setBackground(getResources().getDrawable(R.drawable.button_dark_gradient));
