setOnItemClickListener不适用于android Spinner。这是我的代码:
supplier.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
String msupplier=supplier.getSelectedItem().toString();
Log.e("Selected item : ",msupplier);
}
});

setOnItemClickListener不适用于android spinner。或者,尝试使用此方法:
setOnItemSelectedListener
更改您的代码:
supplier.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
String msupplier=supplier.getSelectedItem().toString();
Log.e("Selected item : ",msupplier);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

1。我认为您应该检查包含微调器的xml文件。确保没有设置android:clickable = "false"
。
2。请检查您的微调器适配器,并确保在getView(int position, View convertView, ViewGroup parent)
方法中,您没有设置任何小部件点击回拨事件,例如Button
,{{1 }},Imageview

OnItemSelectedListener()
与点击侦听器的用途不同。最重要的是,如果再次单击当前选定的项目,它不会触发。在某些情况下,这可能不是问题,但在其他情况下,它可能是。所以真正的答案不是告诉人们使用不同的,可能不合适的听众,而是要解决原始问题。 : - )
幸运的是,我们可以将click侦听器放在适配器上:
public class SpinnerClickAdapter extends BaseAdapter implements SpinnerAdapter {
protected OnItemClickListener listener;
public SpinnerClickAdapter(Context context, ..., OnItemClickListener listener) {
super();
this.listener = listener;
}
@Override
public View getDropDownView(final int position, View convertView, final ViewGroup parent) {
if (convertView == null)
convertView = LayoutInflater.from(context).inflate(R.layout.yourlayout, false);
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (listener != null)
listener.onItemClick((AdapterView<?>) parent, v, position, getItemId(position));
}
});
// ...
return convertView;
}
}
然后我们可以像往常一样使用它,唯一的区别是没有在微调器上设置它而是在适配器上:
Spinner spinner = (Spinner) findViewById(R.id.yourspinner);
SpinnerClickAdapter spinnerAdapter = new SpinnerClickAdapter(context, ..., new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// TODO
}
});
spinner.setAdapter(spinnerAdapter);

我可能会偏离正轨,但考虑建议您使用比OnItemSelectedListener
更宽的OnItemClickListener
来使用Spinners:
supplier.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
//do something here
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
//optionally do something here
}
});

使用getItemAtPosition:
supplier.getItemAtPosition(position).toString();
答案 5 :(得分:1)
使用此
supplier.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

我认为代码中的supplier
表示spinner
,请替换此行
String msupplier=supplier.getSelectedItem().toString();
以下行:
String msupplier= supplier.getItemAtPosition(position).toString();

我遇到过这个问题。 setOnItemClickListener不适用于微调器。我的解决方案如下:
mSpinnerYears.setAdapter(adapter);
mSpinnerYears.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Logger.d(new StringBuilder(2).append("TAG:").append(TAG).toString(),
new StringBuilder(3).append("click pos = ").append(position).append(
mSpinnerYears.getItemAtPosition(position).toString()).toString());
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
