推荐答案

实际上非常简单.

首先在您的ContentProvider中，定义一个变量以引用:

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

public static final String LIMIT_PARAMETER = "LIMIT";

在提供者的Cursor query @Override中定义一些内容来保存您的极限值

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

String limit = uri.getQueryParameter(LIMIT_PARAMETER);

然后将limit传递给SqliteQueryBuilder:

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

然后可以将其与contentResolver一起使用，如下所示:

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 );
