问题描述
我在互联网上进行了大量搜索,但找不到确切的解决方案.这是我上次尝试的链接.
build.gradle(Module.app)详细信息
从版本 1.2.0 开始,您可以使用方法 chipGroup.getCheckedChipIds()
List< Integer>ids = chipGroup.getCheckedChipIds();代表(整数ID:ID){芯片芯片= chipGroup.findViewById(id);//..}
1.1.0版的旧答案:
当前没有直接的API来获取选定的芯片.
但是,您可以遍历 ChipGroup
的子代并检查 chip.isChecked()
.
ChipGroup chipGroup = findViewById(R.id .....);对于(int i = 0; i< chipGroup.getChildCount(); i ++){芯片芯片=(Chip)chipGroup.getChildAt(i);如果(chip.isChecked()){//已选择此芯片.....}}
I search a lot on internet but couldn't find the exact solution. Here is the link that i last tried from SO.Get selected Chips from a ChipGroup
I want to get selected chips from chip group when a button is clicked.
This function contain information of displaying names in RecyclerView
private void getNames() {
List<String> names = Arrays.asList(getResources().getStringArray(R.array.names));
int count = 0;
for ( String name : names){
list.add(new Names(name));
count++;
}
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
namesAdapter = new NamesAdapter(MainActivity.this, list);
recyclerView.setAdapter(namesAdapter);
}
When click on RecyclerView item one chip is added into the ChipGroup here is the function
public void onItemSelected(Names name) {
Chip chip = new Chip(this);
chip.setText(name.getName());
chip.setCloseIconVisible(true);
chip.setCheckable(false);
chip.setClickable(false);
chip.setOnCloseIconClickListener(this);
chipGroup.addView(chip);
chipGroup.setVisibility(View.VISIBLE);
}
This is the image of displaying chips in ChipGroup
Function that is getting values from ChipGroup
public void getChipGroupValues(){
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ChipGroup chipGroup = findViewById(R.id.chipGroup);
for (int i=0; i<chipGroup.getChildCount();i++){
Chip chip = (Chip)chipGroup.getChildAt(i);
Log.i("outside if ", i+ " chip = " + chip.getText().toString());
if (chip.isChecked()){
Log.i("inside if ", i+ " chip = " + chip.getText().toString());
textView.setText(chip.getText().toString());
}
}
}
});
}
This is output

Starting with the version 1.2.0 you can use the method chipGroup.getCheckedChipIds()
List<Integer> ids = chipGroup.getCheckedChipIds();
for (Integer id:ids){
Chip chip = chipGroup.findViewById(id);
//....
}
OLD ANSWER with 1.1.0:
currently there isn't a direct API to get the selected chips.
However you can iterate through the children of the ChipGroup
and check chip.isChecked()
.
ChipGroup chipGroup = findViewById(R.id.....);
for (int i=0; i<chipGroup.getChildCount();i++){
Chip chip = (Chip)chipGroup.getChildAt(i);
if (chip.isChecked()){
//this chip is selected.....
}
}
