这个问题使我头痛不已。基本上,我有一个基于GridView
的Gallery应用。一切正常。但是我希望图像之间具有水平和垂直相等的间距,因此更容易区分彼此。
这是我的activity_main.xml
:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.gallery.MainActivity">
<GridView
android:id="@+id/gridView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:columnWidth="80dp"
android:scrollingCache="true"
android:smoothScrollbar="true"
android:horizontalSpacing="3dp"
android:verticalSpacing="3dp"
android:padding="0dp"
android:clipToPadding="false"
android:clipChildren="true"
android:numColumns="auto_fit"
android:adjustViewBounds="true"
android:gravity="center"
android:stretchMode="columnWidth"/>
</RelativeLayout>
MainActivity.java:
public class MainActivity extends AppCompatActivity {
private GridView gridView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gridView = (GridView) findViewById(R.id.gridView);
gridView.setAdapter(new ImageAdapter(this));
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent i = new Intent(getApplicationContext(), FullScreenAnimationAdapter.class);
i.putExtra("id", position);
startActivity(i);
}
});
}
}
还有ImageAdapter
的{{1}}:
GetView
因此,我将@Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(ctx);
imageView.setImageResource((int)getItem(position));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setLayoutParams(new GridView.LayoutParams(240, 240));
return imageView;
}
和horizontalSpacing
都设置为verticalSpacing
。但是我的应用程序看起来像这样:
所有图像均为3dp
和1920x1080
。
我在做错什么吗?我应该更改xml文件中的某些属性,还是应该为96 dpi
使用不同的ScaleType
?

使用带有layout_weight属性的LinearLayout。
sudo代码可帮助您实现这一想法。
<LinearLayout
layout_orientation="vertical">
<LinearLayout
orientation="horizontal">
<ImageView
layout_weight="1" />
<ImageView
layout_weight="1" />
<ImageView
layout_weight="1" />
</LinearLayout>
<LinearLayout
orientation="horizontal">
<ImageView
layout_weight="1" />
<ImageView
layout_weight="1" />
<ImageView
layout_weight="1" />
</LinearLayout>
</LinearLayout>

尝试以下提及的方式:
In Activity java:
for set space:
mGridView.setHorizontalSpacing(4);
mGridView.setVerticalSpacing(4);
for get Spacing:
mGridView.getHorizontalSpacing()
mGridView.getVerticalSpacing()
In XML
<GridView
android:layout_height="wrap_content"
android:id="@+id/gridView"
android:layout_width="match_parent"
android:numColumns="auto_fit"
android:horizontalSpacing="10dp"
android:verticalSpacing="10dp">
