我正在开发一个Android应用程序,我需要创建一个自定义视图,并且必须在网格视图中重复填充该视图。

以下是我创建视图的代码段

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <LinearLayout 
        android:id="@+id/layoutContent"
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:orientation="horizontal"
        android:background="@drawable/navigationtextheaderbg">

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="TextView" />

    </LinearLayout>

</LinearLayout>

Gridview适配器如下所示,

class GridViewAdapter extends BaseAdapter{

  Context c;
  int[] imageResources;
 String[] arrayTexts;

    GridViewAdapter(Context x,int[] imageResourses, String[] array )
    {
        this.c=x;
        this.imageResources=imageResourses;
        this.arrayTexts=array;
    } 



    @Override
public int getCount() {
    // TODO Auto-generated method stub
    return arrayTexts.length;
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return position;
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub




    View v=View.inflate(c,R.layout.grid,null);
    TextView tv1=(TextView)v.findViewById(R.id.textView1);

    ImageView iv1=(ImageView)v.findViewById(R.id.imageView1);


    tv1.setText(arrayTexts[position]);

    iv1.setBackgroundResource(imageResources[position]);



    return v;
}

}

我正在使用以下代码片段调用此适配器

GridView gridView=new GridView(MainActivity.this);
                                gridView.setNumColumns(4);

                                GridViewAdapter adapter=new GridViewAdapter(MainActivity.this,imageresources,arr1);

                                gridView.setAdapter(adapter);

这里 imageresourses&amp; arr1 分别是图像和字符串的数组。

int[] imageresources= new int[]{R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher};
    String[] arr1={"Ima","hello","yes","no"};

1 个答案:

答案 0 :(得分:0)

您是否将GridView设置为contentView?

setContentView(gridView);

您应该将上面的XML文件设置为适配器类中的contentview。

View v=View.inflate(c,R.layout.grid,null);
