我有一个微调器，用户可以在其中动态输入项目。我想当用户从微调器中选择一个项目来开始另一个活动时。
我用：
...
m_myDynamicSpinner = (Spinner)findViewById(R.id.myspinner);
m_addItemText = (EditText)findViewById(R.id.editTextItem);
Button addButton = (Button)findViewById(R.id.add);
Button removeButton = (Button)findViewById(R.id.remove);
m_adapterForSpinner = new ArrayAdapter(this, android.R.layout.simple_spinner_item);
m_adapterForSpinner.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
m_myDynamicSpinner.setAdapter(m_adapterForSpinner);
m_adapterForSpinner.add("Items List");
....
}
private void addNewSpinnerItem() {
CharSequence textHolder = "" + m_addItemText.getText();
m_adapterForSpinner.add(textHolder);
}
private void clearSpinnerItems() {
m_adapterForSpinner.clear();
m_adapterForSpinner.add("Items List");
}
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
m_addItemText.setText((CharSequence)parent.getItemAtPosition(pos).toString());
if (pos == 1){
Intent intent = new Intent(MainActivity.this, selection.class);
MainActivity.this.startActivity(intent);
}
}
但什么也没发生。
