Android调用密码锁屏校验怎么实现呢？很多朋友到这一步的时候不知如何写代码了，下面小编把我写的核心代码分享出来，有需要的朋友直接拿去修改下即可使用！
1：获取manager
KeyguardManager mKeyguardMgr = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
mKeyguardMgr = getSystemService(KeyguardManager.class);
}
2：创建intent
/**
* 跳转锁屏密码校验页面
*/
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public void showScreenLockPwd() {
Intent intent = mKeyguardMgr.createConfirmDeviceCredentialIntent(null, null);
if (intent != null) {
startActivityForResult(intent, 1101);
} else {
Toast.makeText(this, "intent==null", Toast.LENGTH_LONG).show();
}
}
3：监听回调
/**
* @param requestCode
* @param resultCode
* @param data 锁屏密码校验回调
*/
@Override
public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1101) {
if (resultCode == RESULT_OK) {
Toast.makeText(this, "校验成功", Toast.LENGTH_LONG).show();
} else {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
showScreenLockPwd();
}
}
}
}
4：兼容性问题
小米11上会出现执行两次onactivityresult的情况。
所以在小米11上面延迟一秒执行跳转
//跳转密码校验 没pin码时intent==null
Intent intent = mKeyguardMgr.createConfirmDeviceCredentialIntent(null, null);
if (intent != null) {
if (ClientSdkAppEnv.isMiRom()) {
//小米延迟一秒执行(锁屏验证页面使用android:taskAffinity)，
// 小米11上会出现执行两次onactivityresult的情况
Scheduler.dispatchUI(() -> startActivityForResult(intent, ACTIVITY_FOR_RESULT), Dates.MILLIS_PER_SECOND);
} else {
startActivityForResult(intent, ACTIVITY_FOR_RESULT);
}
} else {
//跳转密码校验 没pin码时intent==null
Toast.makeText(this, "intent==null", Toast.LENGTH_LONG).show();
}
