Android滑动解锁的震动效果

在LockScreen.java类中的LockScreen方法中的

else if (mUnlockWidget instanceof MultiWaveView) {

MultiWaveView multiWaveView = (MultiWaveView) mUnlockWidget;

multiWaveView.setVibrateEnabled(Settings.System.getInt(mContext.getContentResolver(),//通过判断是否设置了触摸震动效果来设置解锁的震动。

Settings.System.HAPTIC_FEEDBACK_ENABLED, 1) != 0);

MultiWaveViewMethods multiWaveViewMethods = new MultiWaveViewMethods(multiWaveView);

multiWaveView.setOnTriggerListener(multiWaveViewMethods);

mUnlockWidgetMethods = multiWaveViewMethods;

还要在这里加入

class MultiWaveViewMethods implements MultiWaveView.OnTriggerListener,

UnlockWidgetCommonMethods {

private final MultiWaveView mMultiWaveView;

private boolean mCameraDisabled;

MultiWaveViewMethods(MultiWaveView multiWaveView) {

mMultiWaveView = multiWaveView;

multiWaveView.setVibrateEnabled(Settings.System.getInt(mContext.getContentResolver(),

Settings.System.HAPTIC_FEEDBACK_ENABLED, 1) != 0);

final boolean cameraDisabled = mLockPatternUtils.getDevicePolicyManager()

.getCameraDisabled(null);

因为滑动解锁主要使用的就是MultiWaveView这个控件，而这个控件是有设置是否振动的属性。
