android - 如何从字符串获取值到文本视图？在安卓中

Question

在我的应用程序中，我想在列表中显示一些项目，我将所有项目保存在 String 数组中并使用代码带来

 String[] activities = getResources().getStringArray(R.array.Contents);

现在我的任务是将这些字符串数组值分配给我的TextView.

有什么建议么？

Answer 1

在 MainActivity.class

String[] activities = getResources().getStringArray(R.array.Contents);
List<RowItem> rowItems;
In onCreate(){
super.onCreate(savedInstanceState);
setContentView(layoutname);
rowItems = new ArrayList<RowItem>();
for (int i = 0; i < titles.length; i++) {
RowItem item = new RowItem(activities[i]);
rowItems.add(item);
}
listView = (ListView) findViewById(id of ListView);
CustomBaseAdapter adapter = new CustomBaseAdapter(this, rowItems);
listView.setAdapter(adapter);
}

在 RowItem 类中

public class RowItem {
 private String activities;
public RowItem(String activities {
this.activities = activities;
}
public String getActivities() {
return activities;
}
public void setactivities(String activities) {
this.activities = activities;
}
@Override
public String toString() {
return activities;
}
}

在 CustomBaseAdapter 类中

public class CustomBaseAdapter extends BaseAdapter {
Context context;
List<RowItem> rowItems;
public CustomBaseAdapter(Context context, List<RowItem> items) {
this.context = context;
this.rowItems = items;
}

private class ViewHolder {
TextView txtActivities;
}

public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;

        LayoutInflater mInflater = (LayoutInflater)
            context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.list_item, null);
            holder = new ViewHolder();

            holder.txtTitle = (TextView) convertView.findViewById(R.id.activities);

            convertView.setTag(holder);
        }
        else {
            holder = (ViewHolder) convertView.getTag();
        }

        RowItem rowItem = (RowItem) getItem(position);


        holder.txtActivites.setText(rowItem.getActivity());


        return convertView;
    }
 }

尝试这个

ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_list_item_1, activities);
mylistView.setAdapter(aa);
