问题描述
我的问题是，我试图打开了一个的ListView 的有1 的TextView 和复选框。我的问题是单击该复选框时，可以说，在第2项，第6项也将被选中，而第10项和第14项，当所有我想要的是第2项中选择了一路。
我曾尝试：
//设置列表适配器，然后设置就行了
ListAdapter listAdapter =新ArrayAdapter（PendingFriendsActivity.this，R.layout.activity_contact_list_item，R.id.contactNameTextView，ContactList）;
AlertDialog.Builder builderSingle =新AlertDialog.Builder（PendingFriendsActivity.this）;
DialogInterface.OnClickListener buttonClicked;
buttonClicked =新DialogInterface.OnClickListener（）{
@覆盖
公共无效的onClick（DialogInterface对话，诠释它）{
切换（这）{
案例DialogInterface.BUTTON_POSITIVE：
的for（int i = 0; I＆LT; sendContactList.size（）;我++）
{
字符串手机，名称;
名称= sendContactList.get（ⅰ）获得（0）;
电话= sendContactList.get（ⅰ）获得（1）;
sendSMS（电话）;
}
打破; 案例DialogInterface.BUTTON_NEGATIVE：
//没有按钮点击
打破;
}
}
};
builderSingle.setOnItemSelectedListener（新AdapterView.OnItemSelectedListener（）{
@覆盖
公共无效onItemSelected（适配器视图＆LT;＆GT;适配器视图，视图观点，INT I，长L）{
RelativeLayout的vwParentRow =（RelativeLayout的）view.getParent（）;
ArrayList的＆LT;串GT;接触=新的ArrayList＆LT;串GT;（）;
最后复选框contactCheckBox =（复选框）vwParentRow.findViewById（R.id.sendCheckBox）;
TextView的contactTextView =（TextView中）vwParentRow.findViewById（R.id.contactNameTextView）;
Toast.makeText（PendingFriendsActivity.this，contactTextView.getText（）的toString（），Toast.LENGTH_LONG。）.show（）; 如果（contactCheckBox.isChecked（））
{
contact.add（fullContacts.get（ⅰ）获得（0））;
contact.add（fullContacts.get（ⅰ）获得（1））;
sendContactList.add（接触）;
}其他{
sendContactList.remove（ⅰ）;
}
} @覆盖
公共无效onNothingSelected（适配器视图＆LT;＆GT;适配器视图）{ }
}）;builderSingle.setCancelable（假）;
builderSingle.setTitle（好友邀请）;
builderSingle.setNegativeButton（取消，buttonClicked）;
builderSingle.setPositiveButton（发送邀请，buttonClicked）;
builderSingle.setAdapter（listAdapter，buttonClicked）;
builderSingle.show（）;
解决方案
尝试是这样的：
AlertDialog.Builder建设者=新AlertDialog.Builder（MainActivity.this）; //做一个清单举行各种颜色的状态
的for（int i = 0; I＆LT; colors.length;我++）{
ColorVO colorVO =新ColorVO（）;
colorVO.setName（颜色[I]）;
colorVO.setSelected（checkedColors [I]）;
colorList.add（colorVO）;
} //做的东西在这里传递这个两个数组只的ArrayList（'颜色'和;'checkedColors'）
builder.setMultiChoiceItems（颜色，checkedColors，新DialogInterface.OnMultiChoiceClickListener（）{
@覆盖
公共无效的onClick（DialogInterface对话，诠释它，布尔器isChecked）{
//设置状态列表中VO
colorList.get（所）.setSelected（器isChecked）;
Toast.makeText（getApplicationContext（），
colorList.get（所）.getName（）++器isChecked，Toast.LENGTH_SHORT）.show（）;
}
}）; builder.setCancelable（假）; builder.setTitle（您的preferred颜色？）; builder.setPositiveButton（OK，新DialogInterface.OnClickListener（）{
@覆盖
公共无效的onClick（DialogInterface对话，诠释它）{
txtSelected.setText（您的preferred颜色..... \\ n）; //保存选定VOS的状态
ArrayList的＆LT; ColorVO＆GT; selectedList =新的ArrayList＆LT;＆GT;（）;
的for（int i = 0; I＆LT; colorList.size（）;我++）{
ColorVO colorVO = colorList.get（ⅰ）;
颜色[I] = colorVO.getName（）;
checkedColors [I] = colorVO.isSelected（）;
如果（colorVO.isSelected（））{
selectedList.add（colorVO）;
}
} 的for（int i = 0; I＆LT; selectedList.size（）;我++）{
//如果元素是去年那么不重视逗号或将其附加
如果（ⅰ= selectedList.size（） - 1）
txtSelected.setText（txtSelected.getText（）+ selectedList.get（ⅰ）.getName（）+，）;
其他
txtSelected.setText（txtSelected.getText（）+ selectedList.get（ⅰ）.getName（））;
}
colorList.clear（）;
}
}）; builder.setNegativeButton（否，新DialogInterface.OnClickListener（）{
@覆盖
公共无效的onClick（DialogInterface对话，诠释它）{
//确保清除列表中不重复这里形成
colorList.clear（）;
}
}）; builder.setNeutralButton（取消，新DialogInterface.OnClickListener（）{
@覆盖
公共无效的onClick（DialogInterface对话，诠释它）{
//确保清除列表中不重复这里形成
colorList.clear（）;
}
}）; AlertDialog对话框= builder.create（）;
dialog.show（）;
希望这可以帮助！
My problem is that I am trying to open up a dialogInterface with a ListView that has a row with 1 TextView and a CheckBox. The problem I have is that when the checkBox is clicked, lets say on item 2, item 6 will also be checked, and item 10, and item 14, and all the way when all I want is item 2 to be picked.
What I have tried:
//setup a list adapter and then set that on the list
ListAdapter listAdapter = new ArrayAdapter(PendingFriendsActivity.this, R.layout.activity_contact_list_item, R.id.contactNameTextView, ContactList);
AlertDialog.Builder builderSingle = new AlertDialog.Builder(PendingFriendsActivity.this);
DialogInterface.OnClickListener buttonClicked;
buttonClicked = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case DialogInterface.BUTTON_POSITIVE:
for(int i = 0; i < sendContactList.size();i++)
{
String phone, name;
name = sendContactList.get(i).get(0);
phone = sendContactList.get(i).get(1);
sendSMS(phone);
}
break;
case DialogInterface.BUTTON_NEGATIVE:
//No button clicked
break;
}
}
};
builderSingle.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
RelativeLayout vwParentRow = (RelativeLayout)view.getParent();
ArrayList<String> contact = new ArrayList<String>();
final CheckBox contactCheckBox = (CheckBox) vwParentRow.findViewById(R.id.sendCheckBox);
TextView contactTextView = (TextView) vwParentRow.findViewById(R.id.contactNameTextView);
Toast.makeText(PendingFriendsActivity.this, contactTextView.getText().toString(),Toast.LENGTH_LONG).show();
if(contactCheckBox.isChecked())
{
contact.add(fullContacts.get(i).get(0));
contact.add(fullContacts.get(i).get(1));
sendContactList.add(contact);
} else {
sendContactList.remove(i);
}
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
builderSingle.setCancelable(false);
builderSingle.setTitle("Friend Invite");
builderSingle.setNegativeButton("Cancel", buttonClicked);
builderSingle.setPositiveButton("Send Invites", buttonClicked);
builderSingle.setAdapter(listAdapter, buttonClicked);
builderSingle.show();
解决方案
Try something like this :
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
// make a list to hold state of every color
for (int i = 0; i < colors.length; i++) {
ColorVO colorVO = new ColorVO();
colorVO.setName(colors[i]);
colorVO.setSelected(checkedColors[i]);
colorList.add(colorVO);
}
// Do something here to pass only arraylist on this both arrays ('colors' & 'checkedColors')
builder.setMultiChoiceItems(colors, checkedColors, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
// set state to vo in list
colorList.get(which).setSelected(isChecked);
Toast.makeText(getApplicationContext(),
colorList.get(which).getName() + " " + isChecked, Toast.LENGTH_SHORT).show();
}
});
builder.setCancelable(false);
builder.setTitle("Your preferred colors?");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
txtSelected.setText("Your preferred colors..... \n");
// save state of selected vos
ArrayList<ColorVO> selectedList = new ArrayList<>();
for (int i = 0; i < colorList.size(); i++) {
ColorVO colorVO = colorList.get(i);
colors[i] = colorVO.getName();
checkedColors[i] = colorVO.isSelected();
if (colorVO.isSelected()) {
selectedList.add(colorVO);
}
}
for (int i = 0; i < selectedList.size(); i++) {
// if element is last then not attach comma or attach it
if (i != selectedList.size() - 1)
txtSelected.setText(txtSelected.getText() + selectedList.get(i).getName() + " ,");
else
txtSelected.setText(txtSelected.getText() + selectedList.get(i).getName());
}
colorList.clear();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// make sure to clear list that duplication dont formed here
colorList.clear();
}
});
builder.setNeutralButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// make sure to clear list that duplication dont formed here
colorList.clear();
}
});
AlertDialog dialog = builder.create();
dialog.show();
