我启动此 Activity (startactivityforresult)，其中包含 ListView 和用于搜索的编辑文本。当用户单击列表项时，OnItemSelected 应该将选定的列表项返回到上一个 Activity 。我单击列表项，但没有任何反应。为什么？
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_origin);
i = getIntent();
ListView lv = (ListView) findViewById(R.id.listView1);
aa = new ArrayAdapter<String>(getApplicationContext(), R.layout.loginlist, orig);
EditText et;
lv.setAdapter(aa);
et = (EditText) findViewById(R.id.editText1);
et.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence cs, int start, int before, int count) {
aa.getFilter().filter(cs);
}
@Override
public void afterTextChanged(Editable s) {
}
});
lv.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
selected = orig[position];
i.putExtra("selection", selected);
setResult(RESULT_OK, i);
finish();
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
setResult(RESULT_CANCELED, i);
finish();
}
});
}
}
最佳答案
更改您的 ListView 监听器。
例如:
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//here you can apply your logic.
}
});
