试图从列表视图中的文本视图中获取值在android中单击事件

Question

我有一个点击事件连接到我的listview,如图所示.

int[] GenusListIDs = { R.id.txt_ID, R.id.txt_Genus, R.id.txt_Count };
        SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.genusitem, cursor_genuslist, service.GenusListColumns, GenusListIDs);

        ListView list_Genus = (ListView)findViewById(R.id.list_Genus);
        list_Genus.setAdapter(adapter);
        list_Genus.setOnItemClickListener(new OnItemClickListener(){
            @Override
            public void onItemClick(AdapterView parent, View view, int position, long id)
            {
                try
                {
                    Log.println(1, "ItemClick", view.toString());
                    TextView tv = (TextView)view;
                    String genus = (String) tv.getText();
                    Intent i = new Intent(getBaseContext(), Cat_Species.class);//new Intent(this, Total.class);
                    /*view
                    i.putExtra("id", id);*/
                    startActivity(i);
                }
                catch(Exception ex)
                {
                    Log.println(1, "item-click-event", ex.getMessage());
                }
            }
        });

我需要根据他们点击的listitem将字符串参数传递给新的intent.我想要传递的值在名为txt_Genus的listitem中.如何从listitem中获取该值以传递给intent？不要注意我的实验请哈哈.

Answer 1

这应该做到这一点.

TextView tv = (TextView)view.findViewById(R.id.txt_Genius);
String genus = tv.getText().toString();

然后把它放到意图中,我想你已经知道了这一点.

i.putExtra("genius", genius);

编辑;

在您的新活动中,您将访问意图并获取额外的捆绑包.然后,您可以访问您在之前活动的意图中放置的任何内容,如下所示;

Bundle extras = getIntent().getExtras();
String genius = extras.getString("genius");
// pop some toast to show the value of genius - not required but shows it works :) 
Toast.makeText(this, "Genius value: " + genius, Toast.LENGTH_SHORT).show();
