我的主要活动中有一个列表视图。在每一行中我都有一个图像视图，当我单击该图像视图时，会出现快速操作（如 ios 中的弹出窗口）。我的要求是，我想将列表视图中的文本设置为另一个活动的文本当我单击快速操作中的操作项时编辑文本。请帮助..

这是我的主要活动

公共类 ExampleActivity 扩展 Activity {

private static final int ID_UP = 1;
private static final int ID_DOWN = 2;
private static final int ID_SEARCH = 3;
private static final int ID_INFO = 4;

private QuickAction quickAction;
private ActionItem nextItem;
private ActionItem prevItem;
private ActionItem searchItem;

private ListView view;
private ContactsAdapter adapter;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    view = (ListView) findViewById(R.id.listView1);
    final Weather weather_data[] = new Weather[] { new Weather(R.drawable.icon, "Cloudy"),
            new Weather(R.drawable.icon, "Showers"),
            new Weather(R.drawable.icon, "Snow"),
            new Weather(R.drawable.icon, "Storm"),
            new Weather(R.drawable.icon, "Sunny")

    };
    adapter = new ContactsAdapter(this, R.layout.main1,
            weather_data);          
}


void functiontorun(View view1) {
     quickAction = new QuickAction(this,QuickAction.HORIZONTAL);
    nextItem = new ActionItem(ID_DOWN, "Next", getResources().getDrawable(
            R.drawable.menu_down_arrow));
    prevItem = new ActionItem(ID_UP, "Prev", getResources().getDrawable(
            R.drawable.menu_up_arrow));
    searchItem = new ActionItem(ID_SEARCH, "Find", getResources()
            .getDrawable(R.drawable.menu_search));

    // use setSticky(true) to disable QuickAction dialog being dismissed
    // after an item is clicked
    prevItem.setSticky(true);
    nextItem.setSticky(true);

    // add action items into QuickAction
    quickAction.addActionItem(nextItem);
    quickAction.addActionItem(prevItem);
    quickAction.addActionItem(searchItem);
    // Set listener for action item clicked
     final int position1 = view.getPositionForView(view1);

    quickAction
            .setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() {
                @Override
                public void onItemClick(QuickAction source, int pos,
                        int actionId) {
                    ActionItem actionItem = quickAction.getActionItem(pos);

                    if (actionId == ID_SEARCH) {
            Intent i=new Intent(ExampleActivity.this,Second.class);
                        i.putExtra("position",position1 );
                        Log.v("position","po" +position1);
                        startActivity(i);

                    } else if (actionId == ID_INFO) {
                        Toast.makeText(getApplicationContext(),
                                "I have no info this time",
                                Toast.LENGTH_SHORT).show();

                    } else {
                        Toast.makeText(getApplicationContext(),
                                actionItem.getTitle() + " selected",
                                Toast.LENGTH_SHORT).show();
                    }
                }
            });

     quickAction.show(view1);

}

}

还有我的另一项活动

公共类第二扩展活动{

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main2);
    EditText d1=(EditText) findViewById(R.id.editText1);
    Bundle bundle = getIntent().getExtras();
    if (bundle != null) {
        final int position = (Integer) bundle.get("position");
        Log.v("position","po1  " +position);
        ArrayList<Weather> array = new ArrayList<Weather>();
        Log.v("position","po1  " +array);

    }
}

}

联系人适配器：

公共类 ContactsAdapter 扩展 ArrayAdapter{

    Context context; 
    int layoutResourceId;    
    Weather data[] = null;
    public ContactsAdapter(Context context, int layoutResourceId, Weather[] data) {
        super(context, layoutResourceId, data);
        this.layoutResourceId = layoutResourceId;
        this.context = context;
        this.data = data;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        WeatherHolder holder = null;

        if(row == null)
        {
            LayoutInflater inflater = ((Activity)context).getLayoutInflater();
            row = inflater.inflate(layoutResourceId, parent, false);

            holder = new WeatherHolder();
            holder.imgIcon = (ImageView)row.findViewById(R.id.imageView1);
            holder.imgIcon.findViewById(R.id.imageView1).setOnClickListener(mBuyButtonClickListener);
            holder.txtTitle = (TextView)row.findViewById(R.id.textView1);
            //((ImageView) row.findViewById(R.id.im)).setOnClickListener(mBuyButtonClickListener);
            row.setTag(holder);
        }
        else
        {
            holder = (WeatherHolder)row.getTag();
        }

        Weather weather = data[position];
        holder.txtTitle.setText(weather.title);
        holder.imgIcon.setImageResource(weather.icon);
        return row;
    }

    static class WeatherHolder
    {
        ImageView imgIcon;
        TextView txtTitle;
    }
    private OnClickListener mBuyButtonClickListener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            ((ExampleActivity) context).functiontorun(v);
        }
    };

}

    private OnClickListener mBuyButtonClickListener = new OnClickListener() {
    @Override
    public void onClick(View v) {
          WeatherHolder  holder = (WeatherHolder) v.getTag;
          String string =  holder.txtTitle .getText();

        ((ExampleActivity) context).functiontorun(string);
    }
};

只需将字符串传递给您的活动并将函数的参数更改为字符串即可运行
