当我单击可扩展列表视图上的一个项目时，移动到下一个活动

Question

我想要发生的只是当我单击可展开列表视图中的一个项目时，它会显示一个新活动。 例如，我的可扩展列表视图中有一个姓名列表（paul、john、mark、james、luke），当我单击#james 时，新活动很好地打开包含有关#james 的信息。

Answer 1

由于我不完全确定您要做什么，这就是 id 启动带有 textview 的活动的方式，它显示点击的人员文本。

ClickListener的实现

@Override
public boolean onChildClick(ExpandableListView parent, View v,int groupPosition, int childPosition, long id) {
    // TODO Auto-generated method stub
    Intent i = new Intent(this, DetailsActivity.class);
    i.putExtra("Name", listDataChild.get(this.listDataHeader.get(groupPosition)).get(childPosititon));
    startActivity(i);
    return true;
}

显示文本的简单活动

public class DetailsActivity extends Activity {

    TextView tv;

    public View onCreate(SavedInstanceState bundle) {
        tv = new TextView(this);

        return tv;
    }

    public void onResume() {
        super.onResume();

        tv.setText(getIntent().getStringExtra("Name", "SomeDefaultValue"));
    }

}

这应该显示如何做到这一点，如果你不能适应你的需要，你可能想看看一个教程:)
