问题
I'm trying to find a way to disable and enable keyboard sound and vibration when tapping keys. I've searched on Stack Overflow and other Android Forums but i didn't found any result.
I've tried AudioManager to enable vibrate mode, but i want to activate the vibrate mode and sound on keyboard.
audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
audioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER,
AudioManager.VIBRATE_SETTING_ON);
Is there any way how to change android.provider.Settings for keyboard sound and vibration ?

As per your comments:
i'm talking about the default keyboard in android , i want to have the ability to disable / enable keyboard sound and vibration when user tap a key in keyboard,( like in Settings of Keyboard )
&
i'm talking about soft keyboard, like in SAMSUNG GALAXY S2 , HTC ONE ...etc
AFAIK, you can not accomplish this as each input method keeps its sound/vibration preference values internally. See for example Android (AOSP) IMe (as of this writing lines 30~39):
<CheckBoxPreference
android:key="vibrate_on"
android:title="@string/vibrate_on_keypress"
android:defaultValue="@bool/config_default_vibration_enabled"
android:persistent="true" />
<CheckBoxPreference
android:key="sound_on"
android:title="@string/sound_on_keypress"
android:defaultValue="@bool/config_default_sound_enabled"
android:persistent="true" />
As you can see it stores the vibrate/sound values in its shared preference. That applies to most of IMe in the market. Hence, you can not control vibrate/sound effect for all IMe's from single point.

Have a look at How to disable default sound effects for all my application or activity for disabling tap-sounds.
To disable Haptic feedback and touch sounds programmatically have a look at http://developer.android.com/reference/android/view/View.html#setHapticFeedbackEnabled(boolean) http://developer.android.com/reference/android/view/View.html#setSoundEffectsEnabled(boolean)
Easier done is by defining the following in your styles.xml
<!-- Application theme. -->
<style name="AppTheme" parent="@android:style/Theme.NoTitleBar.Fullscreen">
<item name="android:soundEffectsEnabled">false</item>
<item name="android:hapticFeedbackEnabled">false</item>
</style>
and in your manifest.xml
<application [...] android:theme="@style/AppTheme" >

Yes, You can do this if you have root access. Its a lengthy process but you can do this :
Step : 1
Create xml file named com.android.inputmethod.latin_preferences.xml and save in assets.
com.android.inputmethod.latin_preferences.xml
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<boolean name="popup_on" value="false" />
<string name="auto_correction_threshold">1</string>
<boolean name="pref_enable_metrics_logging" value="true" />
<boolean name="pref_voice_input_key" value="true" />
<boolean name="pref_key_use_personalized_dicts" value="true" />
<boolean name="pref_key_block_potentially_offensive" value="true" />
<int name="last_shown_emoji_category_id" value="1" />
<boolean name="sound_on" value="false" />
<string name="emoji_recent_keys">[{"Integer":128533}]</string>
<boolean name="auto_cap" value="true" />
<boolean name="show_suggestions" value="true" />
<boolean name="pref_key_use_contacts_dict" value="true" />
<boolean name="next_word_prediction" value="true" />
<boolean name="pref_key_use_double_space_period" value="true" />
<int name="emoji_category_last_typed_id1" value="0" />
<boolean name="vibrate_on" value="false" />
</map>
Step 2 : Copy this file into your application folder (anywhere where you can access) using asset manager for that you need
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
this function will copy file from assets
public static void copyAssets(Context context, String assetPath, String outFilename) {
AssetManager assetManager = context.getAssets();
InputStream in = null;
OutputStream out = null;
try {
in = assetManager.open(assetPath);
File outFile = new File(context.getExternalFilesDir(null), outFilename);
out = new FileOutputStream(outFile);
copyFile(in, out);
} catch (IOException e) {
Log.e(TAG, "Failed to copy asset: " + outFilename, e);
} finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
}
}
if (out != null) {
try {
out.close();
} catch (IOException e) {
}
}
}
}
public static void copyFile(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1) {
out.write(buffer, 0, read);
}
}
Step 3 : overwrite the system preference file system path (destPath) is /data/data/com.android.inputmethod.latin/shared_prefs
public static void copyToSystem(final String sourceFilePath, final String destPath) {
Thread background = new Thread(new Runnable() {
@Override
public void run() {
try {
Process process = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(process.getOutputStream());
//
os.writeBytes("cp -f " + sourceFilePath + " " + destPath + "\n");
os.flush();
os.writeBytes("exit\n");
os.flush();
process.waitFor();
process.waitFor();
} catch (InterruptedException e) {
e.printStackTrace();
Log.e(TAG, e.toString());
} catch (IOException e) {
e.printStackTrace();
Log.e(TAG, e.toString());
}
}
});
background.start();
}
Step 4 : Reboot device
That's all done. These step will off key press sound and key press vibration
