从选定的ListViewItem文本填充TextView
从选定的ListViewItem文本填充TextView
提问于 2014-09-25 05:06:38
每次单击列表视图中的任何文本时，我都希望在新活动中的TextView上调用setText。例如，如果我点击listView中包含"Android“的项目，我希望单词"Android”出现在新的活动中。
在下面找到代码：
public class ThirdMainActivity extends ActionBarActivity {
ListView lvCourses;
String[] courses = { "Android", "HTML 5", "J2SE", "JavaScript", "MySQL", "PHP", "CSS", "JQuery", "C#"};
String[] descr = { "Android Course", "HTML 5 Course", "J2SE Course", "JavaScript Course", "MySQL Course", "PHP Course", "CSS Course", "JQuery Course", "C# Course" };
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_third_main);
lvCourses = (ListView) findViewById(R.id.lvCourses);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, Android.R.layout.simple_list_item_1, courses);
final TextView rr = (TextView)findViewById(R.id.setT);
lvCourses.setAdapter(adapter);
lvCourses.setOnItemClickListener(
new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> lv, View view, int position, long id) {
if(position == 0){
rr.setText(""+descr[0]);
Intent e = new Intent(getApplicationContext(),TeMainActivity.class);
startActivity(e);
}
if(position == 1){
rr.setText(""+descr[1]);
Intent e = new Intent(getApplicationContext(),TeMainActivity.class);
startActivity(e);
}
}
});
}

您不需要检查所有位置状态。只需在onItemClick()上执行此操作
rr.setText(descr[position]);
Intent e = new Intent(getApplicationContext(),TeMainActivity.class);
startActivity(e);如果要将此数据传递给新活动
rr.setText(descr[position]);
Intent e = new Intent(getApplicationContext(),TeMainActivity.class);
e.putExtra("desc", descr[position])
startActivity(e);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
