Question

我有三个AutoCompleteTextView并设置onItemClickListener，请你帮我知道哪个AutoCompleteTextView被点击了

false

Answer 1

使用View比较视图ID的onItemClick参数进行检查。如下所示

if(view.getId() == R.id.editTextUserNamecheck){

 }else if(view.getId() == R.id.editTextPhoneNoNew){

 }else if(view.getId() == R.id.searchProduct){
 }

在public void onItemClick(AdapterView<?> parent, View view, int position, long id)

中使用上面的代码

Answer 2

在onItemClick中

，您可以识别Adapter AdapterView父级，这样您就可以首先识别父适配器。

如下所示

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    if (parent.getAdapter().getClass().equals(ProductAutoCmplt .class)) {
      //do your stuff
    }
    else if(parent.getAdapter().getClass().equals(CustomPhoneArrayAdapterAutoCmplt .class)){ 
//do your stuff
}else if(parent.getAdapter().getClass().equals(CustomArrayAdapterAutoCmplt.class)){
//do your stuff
}
}

使用匿名内部类，我们可以这样做：

txtUserName.setOnItemClickListener((new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            // do your stuff;
        }
    });                              

txtContactNo.setOnItemClickListener((new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            // do your stuff;
        }
    });                          

txtSearchProduct.setOnItemClickListener((new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            // do your stuff;
        }
    });

onItemClickListener用于多个AutoCompleteTextView
