android滑動解鎖震動效果的開啟和取消

如果我們需要根據設定中的觸摸震動開關來開啟和取消滑動解鎖的震動效果，就需要做以下修改了。

在LockScreen.java類中的LockScreen方法中的

複製代碼 代碼如下:else if (mUnlockWidget instanceof MultiWaveView) {
MultiWaveView multiWaveView = (MultiWaveView) mUnlockWidget;

multiWaveView.setVibrateEnabled(Settings.System.getInt(mContext.getContentResolver(),//通過判斷是否設定了觸摸震動效果來設定解鎖的震動。
Settings.System.HAPTIC_FEEDBACK_ENABLED, 1) != 0);

MultiWaveViewMethods multiWaveViewMethods = new MultiWaveViewMethods(multiWaveView);
multiWaveView.setOnTriggerListener(multiWaveViewMethods);
mUnlockWidgetMethods = multiWaveViewMethods;

還要在這裡加入複製代碼 代碼如下: 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);

因為滑動解鎖主要使用的就是MultiWaveView這個控制項，而這個控制項是有設定是否震動的屬性。
