Question

我的应用正在从Firebase检索一个长字符串，并将其显示在列表视图中，但空间不足。末尾有“ ...”，如我所附的图片所示。Heres a picture of what the listview shows

这是我的代码。我该怎么做才能使文本换行/继续到下一行？

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ArrayAdapter;
import android.widget.ListView;

import com.google.firebase.database.ChildEventListener;
import com.google.firebase.database.DataSnapshot;
import com.google.firebase.database.DatabaseError;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;

import java.util.ArrayList;

public class Events extends AppCompatActivity {  ListView listview2;
DatabaseReference dref;
ListView listview3;
ArrayList<String> list=new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.events);
    listview3=(ListView)findViewById(R.id.list_view3);
    final ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,list);
    listview3.setAdapter(adapter);
    dref= FirebaseDatabase.getInstance().getReference("Events");
    dref.addChildEventListener(new ChildEventListener() {
        @Override
        public void onChildAdded(DataSnapshot dataSnapshot, String s) {
            list.add(dataSnapshot.getValue(String.class));
            adapter.notifyDataSetChanged();
        }
        @Override
        public void onChildChanged(DataSnapshot dataSnapshot, String s) {
        }
        @Override
        public void onChildRemoved(DataSnapshot dataSnapshot) {
            list.remove(dataSnapshot.getValue(String.class));
            adapter.notifyDataSetChanged();
        }
        @Override
        public void onChildMoved(DataSnapshot dataSnapshot, String s) {
        }
        @Override
        public void onCancelled(DatabaseError databaseError) {
        }
    });
}

}

Answer 1

确保在布局内添加以下属性：

const express = require('express')
const routes = require('./routes.js)

const app = express()
app.use(routes.routeOne)
app.use(routes.routeTwo)

app.listen(3000)

Answer 2

由于您使用ggplot(df, aes(x=CONDITION, y=SCORE, fill=..y..)) + geom_bar(stat="summary", fun.y="sum") + ggtitle("Performance") + ylab("Total") + scale_y_continuous(labels = scales::percent) + facet_wrap(~TASK) + scale_fill_gradient(low="red", high="blue")，所以只有1行文字。将其替换为simple_dropdown_item_1line

Listview空间不足，无法显示字符串
