Question

我有一个列表视图，在列表视图中我需要通过单击列表项上的图像来获取所选项目位置（我在单击该图像时显示图像颜色更改）。我正在获取列表项的位置通过点击图像，但是，一旦点击图像，我在其他列表项目上获得了另外两个颜色更改图像。我无法找到原因，我的列表大小是13项。它突出显示每5个项目图像颜色一次单击。在这里我使用带有drawable的切换按钮来改变图像颜色。请帮帮我。

这是我的代码这是列表项

上的切换图像

<ToggleButton
                    android:id="@+id/tick_mark"
                    android:layout_gravity="center"
                    android:gravity="center"
                    android:textOff=""
                    android:textOn=""


                    android:background="@drawable/selected"
                    android:layout_width="30sp"
                    android:layout_height="30sp"
                    />

这是我的适配器类

public class Choose_adapter extends BaseAdapter {
ArrayList<Choose_pojo>data;
Activity activity;
LayoutInflater inflater;

LinearLayout more_btn;
public Choose_adapter(Activity context,ArrayList<Choose_pojo> items){
    this.data       =items;
    this.activity   =context;
    inflater        =(LayoutInflater)activity.getSystemService(context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
    return data.size();
}

@Override
public Object getItem(int position) {
    return data.get(position);
}

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

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    View view=convertView;

    if(convertView==null)
    {
        view=inflater.inflate(R.layout.choose_diet_row,null);
    }


    final ToggleButton tick_mark =(ToggleButton)view.findViewById(R.id.tick_mark);



    tick_mark.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {



           IngredientSession.addIndex1(position);
        }
    });

    return view;
}

}

这是我的活动类

public class Choose_activity extends Activity{

Choose_adapter adapter;
ListView lv;
ArrayList<Choose_pojo> list1= Choose_pojo.feedData();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.choose_diet_list);

     lv =(ListView)findViewById(R.id.diet_list);
    loadInitials();
}

private void loadInitials() {
    adapter=new Choose_adapter(this,list1);
    lv.setAdapter(adapter);
}

}

这里我使用pojo类Choose_pojo和静态方法

public class Choose_diet_pojo {
String item_name;
double energy_weight;
double fat_weight;
double fiber_wieght;
double protien_weight;
double Ca_wt;
double AvP_wt;
double Sodium_wt;
double Methionine_wt;
double Lysine;
String title;
String mintitle;

public double getEnergy_weight() {
    return energy_weight;
}

public void setEnergy_weight(double energy_weight) {
    this.energy_weight = energy_weight;
}

public double getFat_weight() {
    return fat_weight;
}

public void setFat_weight(double fat_weight) {
    this.fat_weight = fat_weight;
}

public double getFiber_wieght() {
    return fiber_wieght;
}

public void setFiber_wieght(double fiber_wieght) {
    this.fiber_wieght = fiber_wieght;
}

public double getProtien_weight() {
    return protien_weight;
}

public void setProtien_weight(double protien_weight) {
    this.protien_weight = protien_weight;
}

public double getCa_wt() {
    return Ca_wt;
}

public void setCa_wt(double ca_wt) {
    Ca_wt = ca_wt;
}

public double getAvP_wt() {
    return AvP_wt;
}

public void setAvP_wt(double avP_wt) {
    AvP_wt = avP_wt;
}

public double getSodium_wt() {
    return Sodium_wt;
}

public void setSodium_wt(double sodium_wt) {
    Sodium_wt = sodium_wt;
}

public double getMethionine_wt() {
    return Methionine_wt;
}

public void setMethionine_wt(double methionine_wt) {
    Methionine_wt = methionine_wt;
}

public double getLysine() {
    return Lysine;
}

public void setLysine(double lysine) {
    Lysine = lysine;
}

public String getMintitle() {
    return mintitle;
}

public void setMintitle(String mintitle) {
    this.mintitle = mintitle;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public String getItem_name() {
    return item_name;
}

public void setItem_name(String item_name) {
    this.item_name = item_name;
}

public static ArrayList<Choose_pojo> feedData() {
    ArrayList<Choose_pojo> list = new ArrayList<Choose_pojo>();

    Choose_pojo data1 = new Choose_pojo();
    data1.setTitle("abc");
   data1.setMintitle("ab");
    data1.setEnergy_weight(3373);
    data1.setFat_weight(3.5);
    data1.setFiber_wieght(1.9);
    data1.setProtien_weight(7.5);
    data1.setAvP_wt(0.12);
    data1.setCa_wt(0.01);
    data1.setLysine(0.24);
    data1.setMethionine_wt(0.18);
    data1.setSodium_wt(0.02);

    list.add(data1);


    Choose_pojo data2 = new Choose_pojo();
    data2.setTitle("pqr");
    data2.setMintitle("pq");
    data2.setEnergy_weight(1300);
    data2.setFat_weight(4.0);
    data2.setFiber_wieght(10);
    data2.setProtien_weight(14.8);
    data2.setAvP_wt(0.38);
    data2.setCa_wt(0.14);
    data2.setLysine(0.6);
    data2.setMethionine_wt(0.2);
    data2.setSodium_wt(0.06);
    list.add(data2);
    return list;
}

}

在上面的数据1中，像我这样的数据2达到数据13

列表视图选择突出显示错误
