在我的代码中一切正常,直到我将此代码显示在其他代码中的任何位置,以便访问xml页脚布局中的TextView:
TextView totalTextView = (TextView) footer.findViewById(R.id.total_text);
totalTextView.setText(totalPrice);
total_text
是一个TextView,位于我用作页脚的xml文件中。
此脚注xml布局命名为alternative.xml,它显示在ListView的底部,该ListView使用不同的xml布局填充了适配器填充的其他项目。此页脚布局文件中唯一的内容是名为total_text
的TextView。
如何在页脚xml布局中访问名为TextView
的{{1}}?
以下是Logcat的堆栈跟踪:
total_text
以下是Activity类中的代码:

ArrayAdapter类中嵌套在Activity类中的代码:
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);
编辑:这里要求的是来自alternative.xml的代码:
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;
}
}
答案 0 :(得分:2)
根据堆栈跟踪,看起来您正试图调用totalTextView.setText()
传递int
参数。如果是这种情况,则参数为treated as a resource id。您可能需要使用
totalTextView.setText(Integer.toString(totalPrice));
答案 1 :(得分:1)
这应该可以解决这个问题,基本上TextViews的setText方法需要一个String。
totalTextView.setText(String.valueOf((totalPrice));
