我想在我的活动完全加载后自动单击 Spinner 元素。
我使用此代码来设置微调器和适配器:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_read_data);
getActionBar().setDisplayHomeAsUpEnabled(true);
mSpinnerDay = (Spinner) mTable.findViewById(R.id.spieltag_choice);
mAdapterSpinnerDay = new ArrayAdapter<CharSequence>(this, R.layout.custom_spinner);
mAdapterSpinnerDay.setDropDownViewResource(R.layout.custom_spinner);
mSpinnerDay.setAdapter(mAdapterSpinnerDay);
}
private void setUpSpinnerListener(final IGameData data) {
mSpinnerDay.post(new Runnable() {
public void run() {
mSpinnerDay.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
for (GameDayData d : data.getGameDay()) {
if (d.getName().equals(adapterView.getSelectedItem().toString())) {
TableRow row = (TableRow) mTable.findViewById(R.id.row_punkte_tag);
TextView t = (TextView) row.findViewById(R.id.punkte_tag);
t.setText("Punkte: " + d.getScore());
TableRow row2 = (TableRow) mTable.findViewById(R.id.row_position_tag);
TextView t2 = (TextView) row2.findViewById(R.id.position_tag);
t2.setText("Position: " + d.getPosition());
return;
}
}
}
public void onNothingSelected(AdapterView<?> adapterView) {
return;
}
});
}
});
}
public void onTeamCheckReadComplete(IGameData data) {
for (GameDayData d : data.getGameDay()) {
mAdapterSpinnerDay.add(d.getName());
}
}
将适配器设置为微调器后,我尝试使用以下代码执行单击:
mSpinnerDay.setSelection(0, true);
View view = (View) mSpinnerDay.getChildAt(0);
long id = mSpinnerDay.getAdapter().getItemId(0);
mSpinnerDay.performItemClick(view, 0, id);
但这不起作用。有人可以告诉我如何自动单击微调器元素吗?当我在应用程序中通过触摸事件选择微调器项目时,一切正常。
问候, 桑德罗
