我有像下面的对话警告
当我关闭它然后更新它的项String Array
,
在我再次打开它之后,我看到上面较旧的Dialog
图片和
没有改变。问题是什么?
这是调用Alert Dialog
的代码 public void onClickSafheMojud(View view){
item=null;
Cursor cursor=dbAdapter.getAllData();
int i=0;
if(cursor.moveToFirst()) {
i=1;
while (cursor.moveToNext()){
i++;
}
}
if(i>0) {
CharSequence[] items = new CharSequence[i];
if (cursor.moveToFirst()) {
items[0] = cursor.getString(0);
i = 1;
while (cursor.moveToNext()) {
items[i] = cursor.getString(0);
i++;
}
}
item=items;
showDialog(0);
}
else
}
这是Dialog Alert Builder
@Override
protected Dialog onCreateDialog(int id){
switch (id){
case 0:
AlertDialog.Builder builder2=new AlertDialog.Builder(this);
builder2.setIcon(R.drawable.res);
builder2.setTitle("انتخاب کنید");
builder2.setPositiveButton("برو", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder2.setNegativeButton("لغو", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getBaseContext(), "لغو شد.", Toast.LENGTH_SHORT).show();
}
});
builder2.setSingleChoiceItems(item, 0, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
kodam_safhe=which;
}
});
kodam_safhe=0;
return builder2.create();
return null;
}
答案 0 :(得分:0)
采用全球int
变量。
int test = 0;
setSingleChoiceItems
就像这样
builder2.setSingleChoiceItems(item, test, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
test = which;
}
});
快乐编码..

过了几天我找到答案了
问题是:使用onCreateDialog并覆盖它
我只是创建一个AlertDialog.Builder,然后显示它
我没有使用showDialog()方法
项目每次更新
