我的发言。 清单中的摘录 对Click的看法
原标题:myIntent.putExtra during listView onClick

试图随同和随同附上照片。 播下外语,但并不真正确定在我向下一场活动发送时如何展示形象。

这里是我的卡纳克:

lv.setOnItemClickListener (new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
          // When clicked, bring up Mockactivity.class
      if(position == 1)
      {
          Intent myIntent = new Intent(view.getContext(), mockactivity.class);
          myIntent.putExtra("myDrawable", R.drawable.mydrawable);
          startActivityForResult(myIntent, 0);
      }

It will click, and bring up a blank activity that i have named "mockactivity.class" if i take out the "myIntent.putExtra" line, but when that is there it does nothing. Anyone know how to display that drawable in the next activity that im clicking in to?

最佳回答

<代码>R类别中的所有内容都是代表实际资源的分类。

在另一个<条码>中,你需要使用......这样的东西。

int myDrawableId = getIntent().getIntExtra("myDrawable", -1);

在此情况下,<代码>-1为违约值,如<代码>,将予退还。 斜线(<>/代码>)t 含有与这一名称相加的外壳:myDrawableId,看其是否为-1<<>>>>。

然后,你应当能够使用<代码>myDrawableId,与你使用<代码>R.drawable.mydrawable相同。

http://www.un.org。 采用本法典......

ImageView view = (ImageView) findViewById(...);

......你试图找到<代码>ImageView,而不是用于其图像来源的可图。 你们应当使用......

ImageView view = (ImageView) findViewById(R.id.myImageView);

view.setImageResource(myDrawableId);
