在按钮点击微调不响应Click事件： [英] Spinner on Button click not responding to Click events:

问题描述

我有一个按钮被点击时，它滴下来好手。但是，当我试图设置onItemSelectedListener，它不走的单击事件。

  spnrLocation.setOnItemSelectedListener（新OnItemSelectedListener（）{            @覆盖
            公共无效onItemSelected（适配器视图＆LT;＆GT;母公司，查看ARG1，
                    INT ARG2，长ARG3）{
                的System.out.println（位置点击+ ARG2）;
                edtLocation.setText（parent.getItemAtPosition（ARG2）的ToString（））;
                的System.out.println（wfefe
                        + parent.getItemAtPosition（ARG2）的ToString（））;
            }            @覆盖
            公共无效onNothingSelected（适配器视图＆LT;＆GT;为arg0）{
            }
        }）;
 

解决方案

  //试试这个
spnrLocation.setOnItemClickListener（新AdapterView.OnItemClickListener（）{
            @覆盖
            公共无效onItemClick（适配器视图＆LT;＆GT;适配器视图，视图观点，INT I，长L）{
                的System.out.println（位置点击+ I）;
                edtLocation.setText（spnrLocation.getSelectedItem（）的toString（））;
                的System.out.println（wfefe
                        + spnrLocation.getSelectedItem（）的toString（））;
            }
        }）;
 

I have a spinner which drops down when a button is clicked. But when I am trying to set onItemSelectedListener, it is not taking the click events.

spnrLocation.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> parent, View arg1,
                    int arg2, long arg3) {
                System.out.println("location clicked" + arg2);
                edtLocation.setText(parent.getItemAtPosition(arg2).toString());
                System.out.println("wfefe"
                        + parent.getItemAtPosition(arg2).toString());
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
            }
        });

解决方案

// try this
spnrLocation.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                System.out.println("location clicked" + i);
                edtLocation.setText(spnrLocation.getSelectedItem().toString());
                System.out.println("wfefe"
                        + spnrLocation.getSelectedItem().toString());
            }
        });
