我想在我的 gridview 中添加一个按钮，但是当我拖放按钮并运行项目时，我看到该按钮位于 gridview 的每个字段中...我尝试了一些解决方案，例如制作 2 个线性布局，然后将按钮放入单独的布局，但没有变化！这是代码：

public class gridview extends Activity{
    GridView grid_main;
    Context context;
    TextView tv;
    EditText tx;
    ImageAdapter grid;
    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        context = this;
       setContentView(R.layout.gridview);
        grid_main = (GridView)findViewById(R.id.gridview);
        grid_main.setAdapter(new ImageAdapter(this));
        grid= new ImageAdapter(context);

//        grid_main.setOnItemClickListener(new OnItemClickListener() {
  //          public void onItemClick(AdapterView parent, View v, int position, long id) {
    //            grid .getCount();
      //          grid .getItem(position);
       // }
       // });


    }
    public class ImageAdapter extends BaseAdapter{
        Context mContext;
        public static final int ACTIVITY_CREATE = 10;
        public ImageAdapter(Context c){
            mContext = c;
        }
        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return 5;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            View v;
            if(convertView==null){
                     LayoutInflater inflater = ((Activity)context).getLayoutInflater();
                v= inflater.inflate(R.layout.list_item,parent, false);

                    tv = (TextView)v.findViewById(R.id.textView1);
                    tx = (EditText)v.findViewById(R.id.editText1);
                    tv.setText(""+R.drawable.download);
                    ImageView iv = (ImageView)v.findViewById(R.id.imageView1);
                    iv.setImageResource(mThumbIds[position]);




            }
            else
            {
                v = convertView;
            }
            return v;
        }
        private Integer[] mThumbIds = {
                R.drawable.download,
                R.drawable.download,
                R.drawable.french,
                R.drawable.download,
                R.drawable.download,
                R.drawable.french,
                R.drawable.download,
                R.drawable.download,
                R.drawable.french,
                R.drawable.french
        };
        public Object getItem(int position) {
            return position;
        }

        public long getItemId(int position) {
            return position;
        }
    }
}

xml文件：

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >



<LinearLayout

我猜你只是想有一个 GridLayout 和你的 imageview、textview 和 textedit 并在它们下面你的按钮？尝试这个：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin" >

   <GridLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:columnCount="2"
        android:rowCount="2">

        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/download" />

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

        <EditText
            android:id="@+id/editText1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10" />

    </GridLayout>

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />

如果您没有 Android 4.0 或更高版本，则 GridLayouts 不可用。所以然后使用这个代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >


    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        android:src="@drawable/download" />

    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >

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

        <EditText
            android:id="@+id/editText1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </LinearLayout>

    <Button
        android:id="@+id/button1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Button" />

</LinearLayout>

此解决方案将在顶部显示图像。在左侧的 TextView 下方，右侧的 EditText 和底部的按钮

从网格布局 xml 中删除列表项。使用单独的布局来显示 ListItem

网格视图.xml

<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:layout_width="match_parent"
    android:layout_height="366dp"
    android:orientation="vertical" >

<GridView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:columnWidth="90dp"
    android:gravity="center"
    android:horizontalSpacing="10dp"
    android:numColumns="auto_fit"
    android:stretchMode="columnWidth"
    android:verticalSpacing="10dp" >

</GridView>

 </LinearLayout>

  <LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />

</LinearLayout>
</LinearLayout>

list_item.xml 

<EditText
    android:id="@+id/editText1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:inputType="number" >

    <requestFocus />
</EditText>

</LinearLayout>

更改了您的适配器 getView 方法

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

                LayoutInflater inflater = ((Activity)context).getLayoutInflater();
            v= inflater.inflate(R.layout.list_item,parent, false);

                tv = (TextView)v.findViewById(R.id.textView1);
                tx = (EditText)v.findViewById(R.id.editText1);
                tv.setText(""+R.drawable.download);
                ImageView iv = (ImageView)v.findViewById(R.id.imageView1);
                iv.setImageResource(mThumbIds[position]);



            }
            else
            {
                v = convertView;
            }
            return v;
        }
