Limiting the number of search suggestions, android

问题

Is there a way to limit the number of displayed suggestions, when using the search interface with custom search suggestion?

Thanks!

It's very simple actually.

Firstly in your ContentProvider, define a variable to have a reference to:

public static final String LIMIT_PARAMETER = "LIMIT";

In your Cursor query @Override of the provider define something to hold your limit value

String limit = uri.getQueryParameter(LIMIT_PARAMETER);

Then pass the limit to the SqliteQueryBuilder:

final Cursor cursor = queryBuilder.query(db, projection, selection,
        selectionArgs, null, null, sortOrder, limit);

You can then use it with a contentResolver like so:

getContentResolver().query( 
    SOME_CONTENT_URI.buildUpon().appendQueryParameter(
        YourContentProvider.LIMIT_PARAMETER, yourLimit).build(), 
    mSuggestionProjection, mSelection,
    filterArgArray, ORDER_BY );
