这是我的主要活动。我有一个包含成员的列表。我想点击一个客户并启动MemberInfo活动。
public class MemberMainActivity extends AppCompatActivity implements MemberListAdapter.MemberClickListener{
private MemberViewModel mMemberViewModel;
private List<Member> mMember;
void setMember(List<Member> members) {
mMember = members;
}
public static final int NEW_MEMBER_ACTIVITY_REQUEST_CODE = 1;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_member);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(MemberMainActivity.this, NewMemberActivity.class);
startActivityForResult(intent, NEW_MEMBER_ACTIVITY_REQUEST_CODE);
}
});
RecyclerView recyclerView = findViewById(R.id.recyclerviewcard_member);
final MemberListAdapter adapter = new MemberListAdapter(this);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
mMemberViewModel = ViewModelProviders.of(this).get(MemberViewModel.class);
mMemberViewModel.getAllMember().observe(this, new Observer<List<Member>>() {
@Override
public void onChanged(@Nullable final List<Member> members) {
mMember = members;
// Update the cached copy of the words in the adapter.
adapter.setMember(members);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == NEW_MEMBER_ACTIVITY_REQUEST_CODE && resultCode == RESULT_OK) {
Member member = new Member(data.getStringExtra(NewMemberActivity.EXTRA_REPLY), data.getStringExtra(NewMemberActivity.EXTRA_REPLY2));
mMemberViewModel.insert(member);
} else {
Toast.makeText(
getApplicationContext(),
R.string.empty_not_saved,
Toast.LENGTH_LONG).show();
}
}
public void onMemberClick(int position) {
Log.i("what", "gotpositionroger");
Member member = mMember.get(position);
Log.i("the", "aftergotpositionroger");
MemberInfo.open(this, member.getId());
}
}
这是我的MemberInfo活动。
public class MemberInfo extends AppCompatActivity {
public static void open(Activity activity, long memberid) {
Intent intent = new Intent(activity, MemberInfo.class);
intent.putExtra("MemberID", memberid);
activity.startActivity(intent);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_memberinfo);
-------------Log.i("okay", "memberinfo");---------------
Intent intent = getIntent();
if (intent != null && intent.hasExtra("MemberID")) {
long memberid = intent.getLongExtra("MemberID", -1);
// TODO: get customer details based on customer id
intent.putExtra("MemberID", memberid);
startActivity(intent);
}
else {
Toast.makeText(
getApplicationContext(),
R.string.empty_not_saved,
Toast.LENGTH_LONG).show();
}
}
}
问题是:当我点击一个成员时,它只是加载和加载,几秒钟后,应用程序崩溃。
在我的MemberInfo活动中,我用Log.i标记了一行。当我点击一个成员时,logcat会一次又一次地向我显示相同的Log.i - Log.i会无限重复。
我的应用程序崩溃后,logcat显示:

我认为问题出在MemberInfo代码中,但我无法弄清楚错误。有人可以帮我解决这个问题吗?
答案 0 :(得分:1)
您在MemberInfo活动onCreate
方法中使用“空”意图打开活动:
Intent intent = getIntent();
if (intent != null && intent.hasExtra("MemberID")) {
long memberid = intent.getLongExtra("MemberID", -1);
// TODO: get customer details based on customer id
intent.putExtra("MemberID", memberid);
startActivity(intent);
}
else {
Toast.makeText(
getApplicationContext(),
R.string.empty_not_saved,
Toast.LENGTH_LONG).show();
}
从onCreate中删除它:
intent.putExtra("MemberID", memberid);
startActivity(intent);
在您启动成员信息活动之后,您需要将所有成员ID作为额外信息传递:
long memberid = intent.getLongExtra("MemberID", -1);
答案 1 :(得分:0)
当会员点击
时,您不会调用活动public void onMemberClick(int position) {
Log.i("what", "gotpositionroger");
Member member = mMember.get(position);
Log.i("the", "aftergotpositionroger");
Intent intent=new Intent(getApplicationContext(),MemberInfo.class);
intent.putExtra("id",member.getId());
startActivity(intent);
}
在Meminfoactivity中你应该这样做
Intent intent = getIntent();
if (intent != null && intent.hasExtra("MemberID")) {
long memberid = intent.getLongExtra("MemberID", -1);
// intent.putExtra("MemberID", memberid);
//you cant able to start the activity without new Intent(thid,Example.class)
// startActivity(intent);
}
else {
Toast.makeText(
getApplicationContext(),
R.string.empty_not_saved,
Toast.LENGTH_LONG).show();
}
