android - アプリのクラッシュ: Logcat は、TextView のリソース ID を指定する必要があると言っています

Question

コードを機能させるためにあらゆることを試しましたが、何が問題なのかわかりません。アプリは初回実行時にクラッシュします。

これが私のコードです：

package com.example.smsTest;

import java.util.List;

import android.app.ListActivity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import android.widget.Toast;

public class Messages extends ListActivity {
    Button btnNew;
    private SQLiteAdapter mySQLiteAdapter;

    private BroadcastReceiver mIntentReceiver;
    ListView listview;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.messages);

        btnNew = (Button) findViewById(R.id.btnNew);

        mySQLiteAdapter = new SQLiteAdapter(this);
        mySQLiteAdapter.openToRead();

        List<Message> values = mySQLiteAdapter.getAllMessages();

        ArrayAdapter<Message> adapter = new ArrayAdapter<Message>(this,
                    R.layout.messages, values);

        setListAdapter(adapter);

        btnNew.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                Intent myIntent = new Intent(Messages.this, SMSTest.class);
                startActivity(myIntent);
            }

        });

    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        String item = (String) getListAdapter().getItem(position);
        Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
    }



    @Override
    protected void onResume() {
        super.onResume();

        IntentFilter intentFilter = new IntentFilter("SmsMessage.intent.MAIN");
        mIntentReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                @SuppressWarnings("unchecked")
                ArrayAdapter<Message> adapter = (ArrayAdapter<Message>) getListAdapter();
                Message message = null;

                String msg = intent.getStringExtra("get_msg");

                // Process the sms format and extract body & phoneNumber
                msg = msg.replace("\n", "");
                String body = msg.substring(msg.lastIndexOf(":") + 1,
                        msg.length());
                String sender = msg.substring(0, msg.lastIndexOf(":"));

                message = mySQLiteAdapter.createMessage(sender, body);
                // adapter.add(message);
                adapter.notifyDataSetChanged();
            }
        };

        this.registerReceiver(mIntentReceiver, intentFilter);
    }

    @Override
    protected void onPause() {
        super.onPause();
        this.unregisterReceiver(this.mIntentReceiver);
    }
}

Messages.xml コード:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btnNew"
        android:layout_width="120dp"
        android:layout_height="wrap_content"
        android:text="New" />

    <ListView
        android:id="@android:id/list"
        android:layout_width="wrap_content"
        android:layout_height="435dp" />

</LinearLayout>

そして、これがlogcatです：

クラッシュする理由を教えてください。

ArrayAdapter アダプター = new ArrayAdapter(this, R.layout.messages, values);

2 番目のパラメーター (レイアウト) は TextView である必要があります。確認してください： http://developer.android.com/reference/android/widget/ArrayAdapter.html#ArrayAdapter%28android.content.Context,%20int,%20java.util.List%3CT%3E%29

ビューをインスタンス化するときに使用する TextView を含むレイアウトファイルのリソース ID。

listview に id を指定しているときに xml ファイルで問題が発生しました。コードでこれを確認してください

<ListView
        android:id="@android:id/list"  //change it to android:id="@android:@+id/list"
        android:layout_width="wrap_content"
        android:layout_height="435dp" />
