我在向微调器添加监听器时遇到问题。当我点击某个微调器的项目时，什么也没有发生。这是我的代码:
Button button_marker= (Button) findViewById(R.id.button_markers);
ArrayAdapter<CharSequence> adapter=ArrayAdapter.createFromResource(this, R.array.markers, android.R.layout.simple_spinner_item);
spinner= new Spinner(this);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
button_marker.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
spinner.performClick();
}
});
new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
Log.e("klkl", "klkl");
}
public void onNothingSelected(AdapterView<?> arg0) {
Log.e("klkl", "klkl");
}
});
最佳答案
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
Log.e("klkl", "klkl");
}
public void onNothingSelected(AdapterView<?> arg0) {
Log.e("klkl", "klkl");
}
});
