我的SearchView建议有问题,当我在SearchView中写一个字符时,建议没有到来.
但是当我在SearchView的EditText中写两个字符时,建议就会到来.
但是当我在SearchView的EditText中写两个字符时,建议就会到来.
所以当我在SearchView的EditText中写一个字符时,我希望我的建议已经来了,我该怎么办？
我的MainActivity代码：
private SearchView mSearchView;
private SimpleCursorAdapter mAdapter;
private ArrayList<String> mList;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mList = new ArrayList<String>();
mList.add("Test 1");
mList.add("Test 2");
mList.add("Test 3");
mList.add("Test 4");
mList.add("Test 5");
mList.add("Test 6");
mList.add("Test 7");
mList.add("Test 8");
mList.add("Test 9");
mList.add("Test 10");
ListView listView = (ListView) findViewById(android.R.id.list);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,mList);
listView.setAdapter(adapter);
mAdapter = new SimpleCursorAdapter(getBaseContext(),R.layout.suggestion,null,new String[] {""},new int[] {R.id.suggestion_textView},CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main,menu);
MenuItem searchItem = menu.findItem(R.id.menu_search);
mSearchView = (SearchView) searchItem.getActionView();
mSearchView.setSuggestionsAdapter(mAdapter);
// onItemClick
mSearchView.setOnSuggestionListener(new SearchView.OnSuggestionListener()
{
@Override
public boolean onSuggestionSelect(int position)
{
return false;
}
@Override
public boolean onSuggestionClick(int position)
{
// Only for Test
finish();
return false;
}
});
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener()
{
@Override
public boolean onQueryTextSubmit(String s)
{
return false;
}
@Override
public boolean onQueryTextChange(String s)
{
final MatrixCursor c = new MatrixCursor(new String[] { BaseColumns._ID,"" });
for (int i=0; i < mList.size(); i++)
{
c.addRow(new Object[] {i,mList.get(i)});
}
mAdapter.changeCursor(c);
return false;
}
});
return true;
}
解决方法
我自己找到了解决方案.它不干净但它会起作用.
我调试了SearchView,然后我从SearchView找到了AutoCompleteTextView的ID.比我将AutoCompleteTextView的阈值从2设置为1.现在它可以工作.

mSearchView = (SearchView) searchItem.getActionView();
// Solution
int autoCompleteTextViewID = getResources().getIdentifier("android:id/search_src_text",null);
AutoCompleteTextView searchAutoCompleteTextView = (AutoCompleteTextView) mSearchView.findViewById(autoCompleteTextViewID);
searchAutoCompleteTextView.setThreshold(1);
///////////

for (int i=0; i < mList.size(); i++)
{
if (mList.get(i).toLowerCase().startsWith(s.toLowerCase()))
{
c.addRow(new Object[]{i,mList.get(i)});
}
}
mAdapter.changeCursor(c);
return false;
