Android: saerchable.xml and searchSuggestThreshold parameter

android, android-searchmanager

Solution

Before answer your question there is one thing you have to change in the AndroidManifest.

 <meta-data android:name="android.app.default_searchable"
               android:value=".Search" />

have to be between `<application></application>` tags but not inside `<activity></activity>` ones. Because it declares the default activity to call when a Search intent is fired. After that try if the android:searchSuggestThreshold now works. What you can do as a workaround is in the SearchHelper you are using (the class that manage sql queries) you recieve the search input from the user as the parameter so you can put a simple if. Like this:

public static Cursor getAutoCompleteCursor(String s) {
    Cursor cursor;
    if (s != null && s.length() > 2)
        cursor = searchAutoComplete(s);
    else
        cursor = null;
    return cursor;
}

I hope you understand what I mean. Any doubt just let me know!

Problem

I have a search function in my project. In the searchable.xml, i would like to limit the search only when user types at least 3 characters. This can be done with android:searchSuggestThreshold="3" but in my case, nothing happens, the user can still perform a search when he types on or more characters. Here is my searchable.xml: ``` <searchable xmlns:android="http://schemas.android.com/apk/res/android" android:label="@string/Label" android:hint="@string/Hint" android:searchSuggestThreshold="3" android:includeInGlobalSearch="true"/> ``` Here is the 2 search activityes from the Manifest ``` <activity android:name=".Search" android:configChanges="orientation|keyboardHidden"> <intent-filter> <action android:name="android.intent.action.SEARCH" /> </intent-filter> <meta-data android:name="android.app.searchable" android:resource="@xml/searchable"/> </activity> <activity android:name=".SearchInterface" android:configChanges="orientation|keyboardHidden"> <meta-data android:name="android.app.default_searchable" android:value=".Search" /> </activity> ```
