Java Listview指向选项卡式活动上具有不同文本的同一活动
我是Android编程新手，我需要你的帮助。请 我想做的事 我创建了listview，从listview我创建了ListListener到TabbedActivity 现在，我希望每个listview项在TabbedActivity上显示不同的文本 这是主要的活动：Java Listview指向选项卡式活动上具有不同文本的同一活动,java,android,listview,android-tabbed-activity,Java,Android,Listview,Android Tabbed Activity,我是Android编程新手，我需要你的帮助。请 我想做的事 我创建了listview，从listview我创建了ListListener到TabbedActivity 现在，我希望每个listview项在TabbedActivity上显示不同的文本 这是主要的活动： public class MainActivity extends AppCompatActivity { Toolbar toolbar; ListView listview; @Override protected void
public class MainActivity extends AppCompatActivity {
Toolbar toolbar;
ListView listview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle(getResources().getString(R.string.app_name));
listview = (ListView) findViewById(R.id.listview);

检查图片。多谢各位 在主活动中
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
Intent intent = new Intent(MainActivity.this, TabbedActivity.class);
switch (i){
case 0:
intent.putExtra("Title", "Title1");
break;
case 1:
intent.putExtra("Title", "Title2");
break;
}
startActivity(intent);
}
});
您可以将
textmain活动传递到TabbedActivity
fragmentTab2Simptomi
，如下所示：
1.使用Intent
extras将text
从main活动
传递到tabbed活动
更新onItemClick（）
如下：
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
switch (i){
case 0:
Intent intent = new Intent(MainActivity.this, TabbedActivity.class);
intent.putExtra("YOUR_TEXT", "Text One");
startActivity(intent);
break;
case 1:
Intent intent1 = new Intent(MainActivity.this, TabbedActivity.class);
intent1.putExtra("YOUR_TEXT", "Text Two");
startActivity(intent1);
break;
}
}
});

假设您的片段文本
是静态的
1.使用Intent
extras将文本

传递到tabbed活动
更新onItemClick（）

更新SectionsPagerAdapter
以将文本
传递到片段
：
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
switch (i){
case 0:
Intent intent = new Intent(MainActivity.this, TabbedActivity.class);
intent.putExtra("YOUR_TEXT", "Text One");
startActivity(intent);
break;

intent1.putExtra("YOUR_TEXT", "Text Two");
startActivity(intent1);
break;
}

希望这会有所帮助~您应该使用Intent的附加功能将数据传递给其他活动。。。在询问之前，请做一些研究并阅读官方的android开发者指南。帮助，但没有更改文本。请检查我贴的照片。当做谢谢。在你的问题中，有人问你关于4个片段上的相同文本，我的解决方案将在我检查我的设备时完美实现。若要根据项目选择在不同选项卡上显示不同的文本，则需要以相同的方式传递字符串数组列表。从何处获取这些字符串？从数据库还是其他地方？这很好用谢谢。字符串来自Strings.xml。我可以这样替换文本吗？（intent1.putExtra（“SIMPTOMI”，R.string.opis2）；）
