我是Android Studio的新手，正在为活动创建应用程序。我有主页，带有ImageButton的页面将打开一个新活动-事件信息，其中包含文本和按钮。该应用程序具有底部导航，一旦打开“事件信息”，每次我单击底部导航上的按钮时，它都会打开所需的活动，但是“事件位置”中的按钮位于新活动的顶部。我不能单击所需活动上的任何内容，仅可以单击似乎保留在所有活动顶部的按钮。我没有收到任何关于此的错误，也不知道如何解决。
这是“事件信息”页面的Java代码：
public class EventInformation extends AppCompatActivity {
Button eventLocationButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_event_information);
mTextMessage = (TextView) findViewById(R.id.message);
BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
navigation.setOnNavigationItemSelectedListener(navigationListener);
eventLocationButton = findViewById(R.id.btn_EventLocation);
eventLocationButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent openEventInformation = new Intent(EventInformation.this, Location.class);
startActivity(openEventInformation);
}
});
}
public void setEvent(String event) {
this.event = event;
BottomNavigationView bottomNavigationView = findViewById(R.id.navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(navigationListener);
}
private BottomNavigationView.OnNavigationItemSelectedListener navigationListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
Fragment selectedFragment = null;
switch (item.getItemId()){
case R.id.navigation_home:
selectedFragment = new HomeFragment();
break;
case R.id.navigation_contactInformation:
selectedFragment = new ContactFragment();
break;
case R.id.navigation_location:
selectedFragment = new LocationFragment();
break;
}
getSupportFragmentManager().beginTransaction().replace(R.id.container,
selectedFragment).commit();
return true;
}
};
}
