如何在Android中調試「預期的android.widget.TextView，但發現java.lang.string」？

Question

有人可以看看我的代碼嗎？我正在嘗試爲個人學校項目構建此應用程序。我是android studio的新手。我已經組建了一個簡單的應用程序，您可以在停車場顯示可用空間。

但現在我試圖打開第二個活動屏幕，當我點擊列表視圖屏幕中的其中一個地段。我得到了這個錯誤，並沒有辦法解決它。

**MainActivity.java** 

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout   
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" > 

<TextView 
    android:id="@+id/lotName" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" /> 

<TextView 
    android:id="@+id/lotSpaces" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/lotName"/> 

</RelativeLayout> 

**SingleLotView.java** 

package com.example.sahan.smartpark; 

/**

import android.os.Bundle; 
import android.widget.TextView; 

public class SingleLotView extends Activity{ 

//declare variables 
TextView lotName; 
TextView lotSpaces; 

String[] lot_name; 
String[] lot_spaces; 
int position; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.singlelotview); 
    // Retrieve data from MainActivity on listview item click 
    Intent i = getIntent(); 
    // Get the listview item click position 
    position = i.getExtras().getInt("position"); 
    // Get the list of rank 
    lotName = i.getStringArrayExtra("lotName"); 
    // Get the list of country 
    lotSpaces = i.getStringArrayExtra("lotSpaces"); 
    // Get the list of population 

    // Locate the TextViews in singleitemview.xml 
    lotName = (TextView) findViewById(R.id.move_title); 
    lotSpaces = (TextView) findViewById(R.id.move_title); 

    // Load the text into the TextViews followed by the position 
    lotName.setText(lot_name[position]); 
    lotSpaces.setText(lot_spaces[position]);

**strings.xml** 

<resources> 
<string name="app_name">SmartPark</string> 

<string name="action_settings">Settings</string> 
<string-array name="lot_name"> 
    <item> Parking Lot A</item> 
    <item> Parking Lot B</item> 

</string-array> 

<string-array name="lot_spaces"> 
    <item>Available: 225</item> 
    <item>Available: 107</item> 

</string-array> 

</resources> 

我得到的錯誤是在我SingleLotView.java代碼：

不兼容的類型 - 預計android.widget.TextView卻發現java.lang.String中

Answer 1

lotName = i.getStringArrayExtra("lotName"); 

應該是：

lot_name = i.getStringArrayExtra("lotName");
