Tabs overlapping content in android

Tabs overlapping content in android - java

I am creating a project which has 4 tabs , But when i go to the second tab the content of the first tab persists , and when i go to the third tab the content of the previous two tabs persists.
The tab main xml:
<TabHost
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<TabWidget
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#android:id/tabs"

<FrameLayout
android:layout_width="fill_parent"

This the code for JAVA.
package com.example.healthypet;
import androidx.appcompat.app.AppCompatActivity;
import androidx.cardview.widget.CardView;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private CardView petCard, healthCard,vetCard,overallCard;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
petCard = (CardView) findViewById(R.id.mypet);
healthCard = (CardView) findViewById(R.id.health);

overallCard = (CardView) findViewById(R.id.overall);
}
#Override
public void onClick(View v) {

switch (v.getId()){
case R.id.mypet:
i= new Intent(this,MyPetPage.class);
startActivity(i);
break;

startActivity(i);
break;
default:break;
}
}
}

onClick listener cannot find one of my button fragments. Crashes when initializing button

So when I launch my app it just crashes because the button in my first fragment class cannot be found for some odd reason.
When I removed the
case R.id.button_accept : the program ran fine, so I was thinking it's most likely something I did with the XML in the register_user_fragment. So is there a specific way I need to call the button because there are multiple layouts in one class?
Here's the error.
Caused by: java.lang.IllegalStateException: Required view 'button_accept' with ID 2131296297 for field 'button_accept' was not found. If this view is optional add '#Nullable' (fields) or '#Optional' (methods) annotation.
Here's my baseactivity
public class BaseActivity extends AppCompatActivity implements View.OnClickListener {
//Fragments
Fragment usernameFragment;
Fragment passwordFragment;
//
FragmentManager fragmentManager;
#BindView(R.id.button_login)
Button button_login;
#BindView(R.id.button_accept) //CRASHES HERE.
Button button_accept;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
//check if user is logged in or not
setContentView(R.layout.activity_login);
ButterKnife.bind(this);
usernameFragment = new UsernameFragment();
passwordFragment = new PasswordFragment();
fragmentManager = getFragmentManager();
button_login.setOnClickListener(this);
button_accept.setOnClickListener(this);
//setcontentview register page or whatever use is logged into
}
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.button_login :
Toast.makeText(this, "testds", Toast.LENGTH_SHORT).show();
fragmentManager.beginTransaction()
.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out)
.replace(R.id.content_login, usernameFragment)
.commit();
break;
case R.id.button_accept :
fragmentManager.beginTransaction()
.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out)
.replace(R.id.register_user_fragment, passwordFragment)

Because the "button_accept" is in your fragment layout , not in your activity layout :).
Your binding a UI component that doesn't exist on your activity layout.

You just made your layout mixed. just remove the Button accept_button from frame layout .
The problem is here you have button in a layout parent in which you are placing fragment dynamically. so remove the button to out side or to upper parent and out side the fragment container.

layout weight not working CardView

I want my screen to show a total of 3 cards distributed evenly taking up the whole space but nothing I try seems to be working. The cards are being loaded with the use of a RecyclerView/viewHolder.
I've tried two solutions.
Solution 1:

Change Order Of FrameLayout With Java Code

By default, in my current layout, there are two TextViews at the top and one ImageView at the bottom. I would like to change this by having the ImageView to be at the top and the TextViews be at the bottom using Java. Please help.

Android tabhost issue...code included

I am getting the following error when I try to launch an activity containing a tabhost.
08-25 16:51:42.551:
ERROR/AndroidRuntime(27863):
java.lang.RuntimeException: Unable to
start activity
ComponentInfo{com.paratransit/com.paratransit.jobDialog}:
java.lang.RuntimeException: Could not
create tab content because could not
find view with id 2131165185
This is my code. Can anyone help?
Java
public Class jobDialog extends TabActivity {
TabHost tabs;
int jobCurrentTab = -1;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();
setContentView(R.layout.job_dialog);
tabs = getTabHost();
tabs.setup();
setupTabs();
}
public void setupTabs()
{
TabSpec tspec1 = tabs.newTabSpec("First Tab");
tspec1.setIndicator("Summary", getResources().getDrawable(R.drawable.tab_main)).setContent(R.id.jobDetail1);
tabs.addTab(tspec1);
TabSpec tspec2 = tabs.newTabSpec("Second Tab");
tspec2.setIndicator("Details", getResources().getDrawable(R.drawable.tab_message)).setContent(R.id.jobDetail2);
tabs.addTab(tspec2);
TabSpec tspec3 = tabs.newTabSpec("Third Tab");
tspec3.setIndicator("Notes", getResources().getDrawable(R.drawable.tab_jobs)).setContent(R.id.jobDetail3);
tabs.addTab(tspec3);
XML
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp" />
<LinearLayout
android:id="#+id/jobDetail1"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</LinearLayout>
<LinearLayout
android:id="#+id/jobDetail2"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</LinearLayout>
<LinearLayout
android:id="#+id/jobDetail3"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</LinearLayout>
</LinearLayout>
</TabHost>

I think the 3 linear layouts, jobDetail1->3 should be within the FrameLayout xml element. The point of the FrameLayout is that all of the views are on top of each other, and thus the tab manager can decide which view to show.

I think you're getting this error because you are not including the LinearLayout inside the FrameLayout, besides I think you need to put some element view inside the LinearLayout's.
Something like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:id="#+id/establecimientoView">
<TabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TabWidget android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#android:id/tabs" />
<FrameLayout android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#android:id/tabcontent" >
<LinearLayout
android:id="#+id/tabIdEst"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<include layout="#layout/identificacion_establecimiento"/>
</LinearLayout>
<LinearLayout
android:id="#+id/tabRefGeo"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<include layout="#layout/referencia_geografica"/>
</LinearLayout>
<LinearLayout
android:id="#+id/tabUbicEstablecimiento"
android:layout_width="match_parent"
android:layout_height="match_parent"
