如何訪問腳註xml佈局內的視圖？ Android的

Question

一切正常，在我的代碼罰款，直到我把這裏的其他代碼的任何位置顯示此代碼來獲取XML頁腳佈局內訪問的TextView：

TextView totalTextView = (TextView) footer.findViewById(R.id.total_text); 
    totalTextView.setText(totalPrice); 

total_text是位於XML一個TextView我用作頁腳的文件。

這個腳本xml佈局命名爲alternative.xml，它顯示在ListView的底部，其中填充了由適配器使用不同xml佈局填充的其他項目。該頁腳佈局文件中唯一的內容是名爲total_text的TextView。

我該如何訪問這個TextView叫做total_text裏面的頁腳xml佈局？

下面是從logcat的棧跟蹤：

FATAL EXCEPTION`: main

這裏是在活動類的代碼：在嵌套Activity類的內部一個ArrayAdapter類

listView = (ListView) findViewById(R.id.listView); 

    View footer = getLayoutInflater().inflate(R.layout.alternative, null); 

    TextView totalTextView = (TextView) footer.findViewById(R.id.total_text); 
    totalTextView.setText(totalPrice); 

    listView.addFooterView(footer); 

    MobileArrayAdapter adapter = new MobileArrayAdapter(this, R.layout.row_layout, ckbInfo); 
    listView.setAdapter(adapter); 

代碼：

public class MobileArrayAdapter extends ArrayAdapter<CheckBoxInfo>{ 
     CheckBoxInfo[] objects; 
     Context context; 
     int textViewResourceId; 

    public MobileArrayAdapter(Context context, int textViewResourceId, 
    CheckBoxInfo[] objects) { 
     super(context, textViewResourceId, objects); 
     this.context = context; 
     this.textViewResourceId = textViewResourceId; 
     this.objects = objects; 

     } 

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
View row_layout_view = convertView; 

if ((row_layout_view == null)){ 


    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    row_layout_view = inflater.inflate(R.layout.row_layout, null); 
      }    
//CheckBoxInfo item = objects.get(position); // for arrayList 
CheckBoxInfo item = objects[position]; 

if(item != null){ 

TextView textView = (TextView) row_layout_view.findViewById(R.id.textView1); 
final CheckBox checkBox = (CheckBox) row_layout_view.findViewById(R.id.checkBox1); 
TextView priceTextView = (TextView) row_layout_view.findViewById(R.id.price1); 

checkBox.setOnClickListener(new OnClickListener() { 

@Override 
    public void onClick(View arg0) { 
    final boolean isChecked = checkBox.isChecked(); 
    if(isChecked==true){ 
Toast.makeText(MainActivity.this,"box is checked for position " + position, Toast.LENGTH_SHORT).show(); 
}else if(isChecked==false){ 
Toast.makeText(MainActivity.this,"box is NOT checked for " + position, Toast.LENGTH_SHORT).show(); 
    } 
    } 
     }); 

    if(item !=null){ 
     textView.setText(item.checkBoxName); 
     checkBox.setChecked(item.checkBoxState); 
     priceTextView.setText(String.valueOf(item.price)); 
    } 
     } 
    return row_layout_view; 
    } 

    } 

編輯：這裏要求的是來自alternative.xml的代碼：

<?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" 
    android:gravity="center" > 

    <TextView 
    android:id="@+id/total_text" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="XXXXXX" 
    android:textAppearance="?android:attr/textAppearanceLarge" /> 

</LinearLayout> 

Answer 1

根據堆棧跟蹤，它看起來像你試圖呼叫totalTextView.setText()傳遞int參數。如果是這種情況，參數是treated as a resource id。你可能需要使用

totalTextView.setText(Integer.toString(totalPrice)); 

Answer 2

這應該對你有用，基本上TextViews的setText方法需要一個String。

totalTextView.setText(String.valueOf((totalPrice));
