我想创建一个像gridview说10×20矩阵的矩阵
我们想要指定View的行数和列数,即10×20
如果屏幕很低,它应该水平和垂直滚动
例如,下图描述了Matrix Gridview
每个细胞代表
(0,0)(0,1)等……
(1,0)(1,1)等..
如何生成这种类型的视图?
提前谢谢…. !!!
解决方法:
试试这个:
GridViewCustomAdapter
import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
public class GridViewCustomAdapter extends BaseAdapter {
ArrayList<String> items;
static Activity mActivity;
private static LayoutInflater inflater = null;
public GridViewCustomAdapter(Activity activity, ArrayList<String> tempTitle) {
mActivity = activity;
items = tempTitle;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public final int getCount() {
return items.size();
}
@Override
public final Object getItem(int position) {
return items.get(position);
}
@Override
public final long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View v = null;
v = inflater.inflate(R.layout.item, null);
Button tv = (Button) v.findViewById(R.id.button);
tv.setText(items.get(position));
return v;
}
}
gridview.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:background="@android:color/white"
android:orientation="vertical" >
<GridView
android:id="@+id/grid_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnWidth="20dip"
android:gravity="center"
android:horizontalSpacing="2dp"
android:verticalSpacing="2dp"
android:numColumns="20"
android:stretchMode="columnWidth" >
</GridView>
</LinearLayout>
item.xml
<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/button"
android:layout_width="80dip"
android:layout_height="80dip"
android:textSize="10sp"
android:background="@android:color/holo_blue_light"
android:textColor="@android:color/black"
android:textStyle="bold" />
GridViewActivity
公共类GridViewActivity扩展Activity {
private GridView list;
ArrayList<String> data = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gridview);
for (int i = 0; i < 10; i++) {
for(int j=0;j<20;j++)
data.add(i+"-"+j);
}
GridViewCustomAdapter adapter = new GridViewCustomAdapter(this, data);
list = (GridView) findViewById(R.id.grid_view);
list.setAdapter(adapter);
}
}
输出:
