我正在将我的多选复选框对话框转换为来自公共属性和公共类(所以我可以从任何地方拉它)。
但是,通常当我在课堂上做某事时,我可以使用whatever.ID 和whatever.Name,我猜只是一个普通的多维数组。但是在这种情况下我无法弄清楚语法。
这是我的自定义类:
package com.directenquiries.assessment.tool.Globals;
public class clsNameID {
public String Name;
public String ID;
}
这是创建数组的内容:
public static List<clsNameID> assetHelperTypes(){
Log.e("Asset Helper Types:", "Started");
clsNameID AssetDetails = null;
List<clsNameID> mHelperNames = new ArrayList<clsNameID>();
File dbfile = new File(Global.currentDBfull);
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(dbfile, null);
Cursor f = db.rawQuery("select * from assetobservationtypes", null);
Log.e("Asset Helper Types:", "Cursor run");
if(f.getCount() > 0) {
f.moveToFirst();
while(!f.isAfterLast()) {
AssetDetails = new clsNameID();
AssetDetails.ID = f.getString(f.getColumnIndex("AssetObsID"));
AssetDetails.Name = f.getString(f.getColumnIndex("Observation"));
mHelperNames.add(AssetDetails);
Log.e("Found Item:", AssetDetails.Name);
f.moveToNext();
}
}
f.close();
return mHelperNames;
}
这是我尝试使用数组的地方:
public void addCondition(View view){
List<clsNameID> mHelperNames = DBFunctions.assetHelperTypes();
final List<Integer> mSelectedItems = new ArrayList<Integer>();
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("My Title")
.setMultiChoiceItems(mHelperNames.toArray(new CharSequence[mHelperNames.size()]), null,
new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which, boolean isChecked) {
if (isChecked) {
mSelectedItems.add(which);
} else if (mSelectedItems.contains(which)) {
mSelectedItems.remove(Integer
.valueOf(which));
}
}
})
.setPositiveButton("Save", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
//Create onlcick method
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
//Create onlcick method
}
});
builder.show();
}
我想我真正需要做的是.setMultiChoiceItems(mHelperNames.toArray.Name(new CharSequence[mHelperNames.size()])
但显然这行不通。如何将名称值分配给我的 setMultiChoiceItems 数组?
