房间：无法开始 activity 将 ID 添加到意图

Question

这是我的主activity。我有一个成员列表。我想点击一个客户并启动 MemberInfo activity。

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());
  }
}

这是我的会员信息activity。

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，应用程序崩溃了。

在我的会员信息 activity 中，我用 Log.i 标记了一行。当我单击某个成员时，logcat 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 显示如下：

我认为问题出在 MemberInfo 代码中，但我无法找出错误所在。谁能帮我解决这个问题？

Answer 1

您正在使用 MemberInfo activity onCreate 方法中的 "empty" 意图打开 activity：

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);

启动会员信息后activity您需要做的就是将会员 ID 作为额外传递：

long memberid = intent.getLongExtra("MemberID", -1);

Answer 2

当成员点击时，您没有呼叫 activity

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();
}
