从检查列表视图加载特定字符串？

Question

我有listview的片段

myfragment：

public class LightFragment extends Fragment {
String[] name;
String[] type;
String[] swim;
int[] flag;
ListView list;
ListViewAdapter adapter;

public LightFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_light, container, false);

    name =  getResources().getStringArray(R.array.sport); 

    type = new String[] { "China", "India", "United States",
            "Indonesia", "Brazil" };

    swim = new String[] { "1,354,040,000", "1,210,193,422",
            "315,761,000", "237,641,326", "193,946,886" };

    flag = new int[] { R.drawable.light11,
            R.drawable.light12,             
            R.drawable.light21,
            R.drawable.light22,
            R.drawable.light23,
            R.drawable.light24,
            R.drawable.light25,
            R.drawable.light26,
            R.drawable.light27 };

    // Locate the ListView in fragmenttab1.xml
    list = (ListView) rootView.findViewById(R.id.listview);

    // Pass results to ListViewAdapter Class
    adapter = new ListViewAdapter(getActivity(), name, type, swim,
            flag);
    // Binds the Adapter to the ListView
    list.setAdapter(adapter);
    // Capture clicks on ListView items
    list.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            // Send single item click data to SingleItemView Class
            Intent i = new Intent(getActivity(), SingleItemView.class);
            // Pass all data rank
            i.putExtra("rank", name);
            // Pass all data country
            i.putExtra("country", type);
            // Pass all data population
            i.putExtra("population", swim);
            // Pass all data flag
            i.putExtra("flag", flag);
            // Pass a single position
            i.putExtra("position", position);
            // Open SingleItemView.java Activity
            startActivity(i);
        }

    });

    return rootView;
}

}

Listviewadapter：

public class ListViewAdapter extends BaseAdapter {

// Declare Variables
Context context;
String[] rank;
String[] country;
String[] population;
int[] flag;
LayoutInflater inflater;

public ListViewAdapter(Context context, String[] rank, String[] country,
        String[] population, int[] flag) {
    this.context = context;
    this.rank = rank;
    this.country = country;
    this.population = population;
    this.flag = flag;
}

public int getCount() {
    return rank.length;
}

public Object getItem(int position) {
    return null;
}

public long getItemId(int position) {
    return 0;
}

public View getView(int position, View convertView, ViewGroup parent) {

    // Declare Variables
    TextView txtrank;
    TextView txtcountry;
    TextView txtpopulation;
    ImageView imgflag;

    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View itemView = inflater.inflate(R.layout.listview_item, parent, false);

    // Locate the TextViews in listview_item.xml
    txtrank = (TextView) itemView.findViewById(R.id.name);
    txtcountry = (TextView) itemView.findViewById(R.id.type);
    txtpopulation = (TextView) itemView.findViewById(R.id.swim);
    // Locate the ImageView in listview_item.xml
    imgflag = (ImageView) itemView.findViewById(R.id.flag);

    // Capture position and set to the TextViews
    txtrank.setText(rank[position]);
    txtcountry.setText(country[position]);
    txtpopulation.setText(population[position]);

    // Capture position and set to the ImageView
    imgflag.setImageResource(flag[position]);

    return itemView;
}

}

mysingleviewitem：

public class SingleItemView extends Activity {

TextView txtname;
TextView txttype;
TextView txtswim;
TextView txtfunny;
TextView txtwalking;
TextView txtangry;
TextView txtsad;
ImageView imgflag;
String[] name;
String[] type;
String[] swim;
String[] funny;
String[] walking;
String[] angry;
String[] sad;
int[] flag;
int position;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.singleitemview);

    Intent i = getIntent();
    // Get a single position
    position = i.getExtras().getInt("position");
    // Get the list of rank
    name = i.getStringArrayExtra("rank");
    // Get the list of country
    type = i.getStringArrayExtra("country");
    // Get the list of population
    swim = i.getStringArrayExtra("population");

    funny = i.getStringArrayExtra("rank");
    // Get the list of country
    walking = i.getStringArrayExtra("country");
    // Get the list of population
    angry = i.getStringArrayExtra("population");

    sad = i.getStringArrayExtra("rank");
    // Get the list of flag
    flag = i.getIntArrayExtra("flag");

    // Locate the TextViews in singleitemview.xml
    txtname = (TextView) findViewById(R.id.name);
    txttype = (TextView) findViewById(R.id.type);
    txtswim = (TextView) findViewById(R.id.swim);
    txtfunny = (TextView) findViewById(R.id.funny);
    txtwalking = (TextView) findViewById(R.id.walking);
    txtangry = (TextView) findViewById(R.id.angry);
    txtsad = (TextView) findViewById(R.id.sad);

    // Locate the ImageView in singleitemview.xml
    imgflag = (ImageView) findViewById(R.id.flag);

    // Load the text into the TextViews followed by the position
    txtname.setText(name[position]);
    txttype.setText(type[position]);
    txtswim.setText(swim[position]);
    txtfunny.setText(funny[position]);
    txtwalking.setText(walking[position]);
    txtangry.setText(angry[position]);
    txtsad.setText(sad[position]);

    // Load the image into the ImageView followed by the position
    imgflag.setImageResource(flag[position]);
}

}

myarray：

<string-array name="sport">
    <item >Lari</item>
    <item >Bola</item>
    <item >Balap</item>
    <item >tinju</item>
    <item >renang</item>
</string-array>


<string-array name="Lari">
    <item >100 meter</item>
    <item >mulai</item>
    <item >finish</item>
    <item >piala</item>
</string-array>

细节： ListViewItem，其字符串数组为“sport”，并根据数组字符串的布局进行管理。

点击后会打开singleviewitem列表视图，但我希望根据<string-array name = "Lari">

的列表视图显示从<string-array name = "sport">开始的字词等等

所以例如我单击listview，运行标题将是

<item >100 meter</item>
<item >mulai</item>
<item >finish</item>
<item >piala</item>

请帮忙，

抱歉，我的英语不好

nb：我尝试过getstringarray这个位置，但只根据点击的列表视图的位置提升字符串

Answer 1

由于声誉，我不能发表评论，但您可以简单地从所选数组中获取文本并将其与任何名称进行比较。 如果我理解正确你的问题是你无法从res /数组加载数组，其名称与listview中点击的项目相同。

我通过搜索数组点击的单词来解决它，如果匹配 - 接受它。 onItemClickListener内的所有操作 例如：

String[] myString = null;
String text = parent.getItemAtPosition(position).toString();

if(text.equalsIgnoreCase("Lari")){
    myString = getResources().getStringArray(R.array.lari);
}else if(text.equalsIgnoreCase("sport")){
    myString = getResources().getStringArray(R.array.sport);
}

然后你可以通过意图传递这个数组并填充你的下一个listview。 我希望这就是你想要的。

编辑：当您获得点击的listitem的名称时，您可能会在res / arrays中找到相同的数组。 之后，只需通过Intent传递此数组，然后使用Adapter填充此数组的下一个列表。

Intent intent = new Intent(this, YourNextActivity.class);
intent.putExtra("justNameForArray", mString);

在下一个活动中，您可以获得此数组：

Intent intent = getIntent();
String[] arrayFromPreviousClass = intent.getStringArrayExtra("justNameForArray");

之后你可以填写新名单。

如果你说你想要第三个列表项，你可以在onItemClickListener内找到它：

    switch(position){
        case 0:
            //do smthg;
        break;
        case 1:
           //do smthg;
        break;
        case 2:
        //here you may get your string array and pass it through intent to another activity with another view
        break;
   }
