我在 Listview 中使用 gridview，但我有一个可聚焦的问题。

我已经设置了gridview的宽度，但是我填充了gridview的一些项目，在gridview的左侧空间（空白）意味着listview中没有填充gridview的项目。如果我点击它，它不会执行列表项点击

在此处输入图像描述

如图所示，如果单击列表项中的任何位置，我想执行列表视图项单击。我想要一个 listitem click。

但是当我点击ListView项目时，也就是说，GridView点击ListItem不起作用......

public class History extends Activity {

    String name, id, description, count, total;

    ArrayList<String> TAG_ID = new ArrayList<String>();
    ArrayList<String> TAG_COFFEESHOP_NAME = new ArrayList<String>();
    ArrayList<String> TAG_COUNT = new ArrayList<String>();
    ArrayList<String> TAG_TOTAL = new ArrayList<String>();

    Context context;
    JSONArray CoffeeUser = null;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listlayout);
        ListView listView = (ListView) findViewById(R.id.listnew);
        listView.setAdapter(new MyCustomAdapter());
        listView.setTextFilterEnabled(true);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener()
        {
            public void onItemClick(AdapterView<?> paramAnonymousAdapterView, View paramAnonymousView, int paramAnonymousInt, long paramAnonymousLong)
            {
                Intent intent = new Intent();
                intent.putExtra("coffeeshopid", ((TextView)paramAnonymousView.findViewById(R.id.hlcoffeeshopid)).getText() );

您可能已经解决了它，但我有另一个解决方案可以帮助某人。

android:descendantFocusability="beforeDescendants"在 list_cell XML的根布局中使用。

为了在其他列表中有列表。您必须生成自定义视图。如果您想要一个简单的，由一个 Java 类和一个 XML 文件组成，那么您只需在代码中实例化它并将其添加到线性布局中。

这里我留下一个小例子。

XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical" >

    <TextView
        android:id="@+id/txtAltaPropinaTextoAyudaTipo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="5dp"
        android:layout_marginTop="5dp"
        android:gravity="center_vertical"
        android:text="-"
        android:textColor="#000000"
        android:textSize="18sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/txtListadoZonasNombreZona"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginRight="5dp"
        android:layout_marginTop="5dp"
        android:layout_toLeftOf="@+id/txtAltaPropinaTextoAyudaTipo"
        android:layout_toRightOf="@+id/txtAltaPropinaTextoAyudaTipo"
        android:singleLine="true"
        android:text="TextView"
        android:textColor="#000000" />
</RelativeLayout>

Java 代码

public class CVTexto extends RelativeLayout {

    public TextView txtTexto;
    public int idCv;

    public CVTexto(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
        IniciarCuadro();
    }

    public CVTexto(Context context, AttributeSet attrs) {

        super(context, attrs);
        IniciarCuadro();
    }

    public CVTexto(Context context, AttributeSet attrs, int defStyle) {

        super( context, attrs, defStyle );
        IniciarCuadro();
    }

    private void IniciarCuadro()
    {
        //Utilizamos el layout 'control_login' como interfaz del control
        String infService = Context.LAYOUT_INFLATER_SERVICE;
        LayoutInflater li =
            (LayoutInflater)getContext().getSystemService(infService);
        li.inflate(R.layout.ll_adapter_listado_zonas_asignadas_usuario, this, true);

        AsignarElemetos();
        //Obtenemoslas referencias a los distintos control

        //Asociamos los eventos necesarios
        // asignarEventos();
    }

    private void AsignarElemetos(){
        txtTexto = (TextView)findViewById(R.id.txtListadoZonasNombreZona);
    }
}

添加到线性布局：

cvTextp objCV = new  cvTexto(context);
LinearLayout.addView(objCv);

并删除视图：

LinearLayout.removeallViews;

我通过将网格布局更改为 LinearLayout 得到了这个答案。我将项目动态添加到linearLayout中，然后我的问题就解决了。

我已经对其进行了研究，并且我知道在使用适配器的可滚动小部件内部，您不应该使用任何其他可滚动的小部件，由于触摸事件的复杂性，它也使用了列表视图中的 gridview 等适配器。

所以我认为你应该为此转向另一种方法。在您的情况下，您可以添加线性布局，并可以通过设置参数将杯子图像动态添加到该布局中。我希望这对你有所帮助。

我不知道你下面的代码是如何工作的，但如果我想处理每个点击监听器，那么我会做类似下面的事情。

for (int i = 0; i < looplimit; i++) {

    Log.e("loop", String.valueOf(looplimit));
    ImageView imageView = new ImageView(CopyOfHistory.this);
    if (i < Integer.parseInt(TAG_COUNT.get(paramInt))) {
        imageView.setImageDrawable(getResources().getDrawable(R.drawable.ii));
    } 
    else {
        imageView.setImageDrawable(getResources().getDrawable(R.drawable.iii));
    }
    RelativeLayout layout = (RelativeLayout) localView.findViewById(R.id.hlrlayout);
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(30,30);
    params.setMargins(i*40, 0, 0, 0);
    imageView.setLayoutParams(params);
    layout.addView(imageView);
    //holder.relativeLayout = new RelativeLayout();

    // Handle your each on-click of dynamic added view while they added in getview() method
    imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
          // Do what is necessary
        }
    });
}
