我需要将默认值文本“选择你的设备”值设置为我的微调器下拉列表,我把它作为列表项,所以它作为一个下拉列表项,我隐藏下拉列表,因为这我的下拉菜单中有一个空白区域.
我该怎么做？
这是我用过的代码
mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
/*Setup a Spinner*/
mToolbarSpinner = (Spinner) findViewById(R.id.spinner_toolbar);
/*Manage the spinner*/
mToolbarSpinnerNavigationItems = new ArrayList();
mToolbarSpinnerNavigationItems.add(new SpinnerNavItem("Select your Seebo", R.drawable.deviceonline));
/*setting the mToolbarSpinnerNavigationItems to list_item_title_navigation.xml*/
mArrayAdapter = new ArrayAdapter(this, R.layout.list_item_title_navigation,mToolbarSpinnerNavigationItems){
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// remember to inflate custom layout for spinner item
// then set anything you want here
// remember to use convertView.findViewById(), not just findViewById()
// this is an example
// inflate layout
convertView = View.inflate(MainActivity.this, R.layout.list_item_title_navigation, null);
// get view
TextView tvText1 = (TextView) convertView.findViewById(R.id.devicetitle);
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.deviceicon);
imgIcon.setVisibility(View.GONE);
//imgIcon.setImageResource(mToolbarSpinnerNavigationItems.get(position).getIcon());
// set content
tvText1.setText(mToolbarSpinnerNavigationItems.get(position).getTitle());
// return
return convertView;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
return convertView;
}
};
//setting adapter to Spinner
mToolbarSpinner.setAdapter(mArrayAdapter);
