如何使用选项卡式活动将两个文本传输到列表视图 [英] How to transfer two texts to a listview using tabbed activity

问题描述

我已经使用带有两个标签的viewpager创建了一个标签式活动，我想从标签一（包含两个edittexts）向标签2（包含列表视图）发送两个文本作为标题和描述。 
 
 my fragment_one.java：
 
< pre> 
 public void onViewCreated（View view，@ Nullable Bundle savedInstanceState）{
 super.onViewCreated（view，savedInstanceState）; 
 
 Button btnPassData =（Button）view.findViewById（R.id.btnPassData）; 
 final EditText inData =（EditText）view.findViewById（R.id.inMessage）; 
 btnPassData.setOnClickListener（new View.OnClickListener（）{
 @Override 
 public void onClick（View v）{
 SM.sendData（inData.getText（）。toString（） .trim（））; 
} 
}）; 
 
} 
 
和fragment_two.java：
 
 
 public void onViewCreated（View view，@ Nullable Bundle savedInstanceState）{
 super.onViewCreated（view，savedInstanceState）; 
 
 listView =（ListView）view.findViewById（R.id.list_view）; 
 adapter = new ArrayAdapter< String>（getActivity（），android.R.layout.simple_list_item_1，arrayList）; 
 
 listView.setAdapter（adapter）; 
} 
 
 protected void displayReceivedData（String message）{
 arrayList.add（message）; 
 adapter.notifyDataSetChanged（）; 
 
} 
 
我的custom_listview是：
 
 
< ImageView 
 android：id =@ + id / icon
 android：layout_width =60dp
 android：layout_height =60dp
 android：padding =5dp/> 
 
< LinearLayout android：layout_width =wrap_content
 android：layout_height =wrap_content
 android：orientation =vertical> 
 
< TextView 
 android：id =@ + id / item
 android：layout_width =wrap_content
 android：layout_height =wrap_content
 android：text =中文
 android：textAppearance =？android：attr / textAppearanceMedium
 android：layout_marginLeft =10dp
 android：layout_marginTop =5dp
 android：padding =2dp
 android：textColor =＃33CC33/> 
< TextView 
 android：id =@ + id / textView1
 android：layout_width =wrap_content
 android：layout_height =wrap_content
 android： text =TextView
 android：layout_marginLeft =10dp/> 
< / LinearLayout> 
 
 main activity.java：
 
公共类MainActivity扩展AppCompatActivity实现FragmentOne.SendMessage {
 
 TabLayout tabLayout; 
 ViewPager viewPager; 
 ViewPagerAdapter viewPagerAdapter; 
 
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.activity_main）; 
工具栏工具栏=（工具栏）findViewById（R.id.toolbar）; 
 setSupportActionBar（toolbar）; 
 
 viewPager =（ViewPager）findViewById（R.id.viewPager）; 
 viewPagerAdapter = new ViewPagerAdapter（getSupportFragmentManager（））; 
 viewPager.setAdapter（viewPagerAdapter）; 
 tabLayout =（TabLayout）findViewById（R.id.tabs）; 
 tabLayout.setupWithViewPager（viewPager）; 
} 
 
 @Override 
 public void sendData（String message）{
 String tag =android：switcher：+ R.id.viewPager +： + 1; 
 FragmentTwo f =（FragmentTwo）getSupportFragmentManager（）。findFragmentByTag（tag）; 
 f.displayReceivedData（message）; 
} 
} 

我的尝试：

我试过这个但它不起作用......！ 
< pre> messageModel.setTitle（title.getText（）。toString（）。trim（））; 
 messageModel.setDesc（message.getText（）。toString（）。trim（））;

I have created a tabbed activity with viewpager with two tabs and I want to send two text as title and description from tab one(contains the two edittexts) to tab two(contains the listview).

 my fragment_one.java :

<pre>
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
 
    Button btnPassData = (Button) view.findViewById(R.id.btnPassData);
    final EditText inData = (EditText) view.findViewById(R.id.inMessage);
    btnPassData.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            SM.sendData(inData.getText().toString().trim());
        }
    });
 
}

and fragment_two.java :


public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
 
    listView = (ListView) view.findViewById(R.id.list_view);
    adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, arrayList);
 
    listView.setAdapter(adapter);
}
 
protected void displayReceivedData(String message) {
    arrayList.add(message);
    adapter.notifyDataSetChanged();
 
}

and my custom_listview is :


<ImageView
    android:id="@+id/icon"
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:padding="5dp" />
 
<LinearLayout android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical">
 
    <TextView
        android:id="@+id/item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Medium Text"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="5dp"
        android:padding="2dp"
        android:textColor="#33CC33" />
    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        android:layout_marginLeft="10dp"/>
</LinearLayout>

main activity.java :

public class MainActivity extends AppCompatActivity implements FragmentOne.SendMessage{
 
    TabLayout tabLayout;
    ViewPager viewPager;
    ViewPagerAdapter viewPagerAdapter;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
 
        viewPager = (ViewPager) findViewById(R.id.viewPager);
        viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager());
        viewPager.setAdapter(viewPagerAdapter);
        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
    }
 
    @Override
    public void sendData(String message) {
        String tag = "android:switcher:" + R.id.viewPager + ":" + 1;
        FragmentTwo f = (FragmentTwo) getSupportFragmentManager().findFragmentByTag(tag);
        f.displayReceivedData(message);
    }
}

What I have tried:

I have tried this but it does not work ....!
<pre>messageModel.setTitle(title.getText().toString().trim());
                messageModel.setDesc(message.getText().toString().trim());
