android - 按钮单击上的微调器未响应单击事件：

Question

我有一个微调器，当单击按钮时它会下降。但是当我试图设置 onItemSelectedListener 时，它并没有接受点击事件。

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) {
            }
        });

Answer 1

// 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());
            }
        });

Answer 2

AnyView支持android:clickable属性（它可以让任何View行为都像 a Button）。还有android:focusable。
