Question

我有一个微调名称床，其值为1,2,3,4，由另一个类文件提取，并且所选项目发送到数据库，知道数据库返回的数据类似于所选的微调器值。知道此代码为我工作很好 将床的微调值传递给另一个类的代码

             Intent i= new Intent(SearchByBed.this,SearchBedView.class);
             Bundle bbed= new Bundle();
             bbed.putString("bedValue", spinn_Bed.getSelectedItem().toString());
             i.putExtras(bbed);
             startActivity(i);

接收微调器值并将其发送到db

的代码

           Bundle bbedview = this.getIntent().getExtras();
           String name = bbedview.getString("bedValue");
           cursor = info.getBed(name);

db中的

代码执行搜索和返回值

      public Cursor getBed(String l) {
      String[] columns = new String[] { KEY_ROWID, KEY_TITLE, KEY_TYPE,
      KEY_BEDROOMS, KEY_STATUS, KEY_CITY, KEY_LOCALITY, KEY_PRICE,
      KEY_TOTPRICE, KEY_FURNISHING, KEY_BALCONIES, KEY_BATHROOM };
      Cursor c = ourDatabase.query(DATABASE_TABLE, columns,    
          KEY_BEDROOMS + "=" + l, null, null, null, null);
      return c;}

类似地知道我用于微调器名称类型的相同代码

String[] propertyType = { "Residental Apartment","Independent House/Villa", "Shops", "Agricultural/Farm Land" };
Intent i = new Intent(SearchByPropType.this,SearchPropView.class);
Bundle bprop = new Bundle();
bprop.putString("property", spinn_PropType.getSelectedItem().toString());
i.putExtras(bprop);
startActivity(i);

Bundle bprop = this.getIntent().getExtras();
String property = bprop.getString("property");

public Cursor getProperty(String n) {
String[] columns = new String[] { KEY_ROWID, KEY_TITLE, 
KEY_TYPE, KEY_BEDROOMS, KEY_STATUS, KEY_CITY, 
KEY_LOCALITY, KEY_PRICE, KEY_TOTPRICE, KEY_FURNISHING,
KEY_BALCONIES, KEY_BATHROOM };
Cursor c = ourDatabase.query(DATABASE_TABLE, columns,
 KEY_TYPE + "=" + n, null, null, null, null);
return c;}

但是对于另一个微分名称类型，其值为“Residental Apartment”，“Independent House / Villa”，“Shops”我正在执行相同的过程
但是app显示错误
