故障截图，Activity 在不断的获取焦点和失去焦点
image.png
- 导致的原因
- 在登录的Activity中的生命周期onResume中使用RxPermissions获取相机的权限，点击不让通知，拒绝权限了，这个Activity就会不断的onResumed onPaused 生命周期轮训，其他手机上没有这种问题！只在oppoR 9上有这种的问题，
- 解决的办法
- 把权限的检查放到onCreate的方法中，就可以解决！
if (!aBoolean){
final RxPermissions rxPermissions = new RxPermissions(this);
rxPermissions.request(Manifest.permission.CAMERA).subscribe(new Action1<Boolean>() {
@Override
public void call(Boolean aBoolean) {
if (aBoolean) {
boolean granted = rxPermissions.isGranted(Manifest.permission.CAMERA);
if (!granted){
ToastUtils.toast(LoginActivity.this,"相机权限授权成功!");
}
PreferenceUtil.saveValue(PreferenceFileNames.USER_CONFIG, PreferenceKeys.HAS_CAMER_PERMISSION,true);
} else {
ToastUtils.toast(LoginActivity.this,"相机权限授权失败!");
}
}
});
}
RxPermissions 还可能导致整个View的生命周期紊乱的发生
