I have 3 fragment and 2 framelayout in 1 XML file in here , the first 2 fragment is a text and it display normally , but when i replaced the third fragment which have seekbar then it went disappear !
But if i display the third fragment first then the seekbar display normal and the TextView went gone ! This is my code :
MainActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1 = (Button)findViewById(R.id.btn1);
btn2=(Button)findViewById(R.id.btn2);
btn3=(Button)findViewById(R.id.btn3);
fragment1= new Fragment1();
fragment2 = new Fragment2();
fragment3 = new Fragment3();
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
replaceFragment(fragment1,R.id.fragment1,"FRG1");
}
});
btn2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
replaceFragment(fragment2,R.id.fragment2,"FRG2");
}
});
btn3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
replaceFragment(fragment3,R.id.fragment2,"FRG3");
}
});
}
public void replaceFragment(Fragment fragment , int containerResId, String tag){
android.support.v4.app.FragmentTransaction trans = getSupportFragmentManager()
.beginTransaction();
trans.replace(containerResId , fragment , tag);
trans.commit();
getSupportFragmentManager().executePendingTransactions();
}
fragment 1 :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.fragment1,container,false);
return view;
}
Fragment 2 and 3 is same as fragment1 .
This is main.xml :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.macbook.fragment.MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="fragment1"/>
<Button
android:id="#+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="fragment2"/>
<Button
android:id="#+id/btn3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="fragment3"/>
</LinearLayout>
<FrameLayout
android:id="#+id/fragment1"
android:layout_weight="5"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</FrameLayout>
<FrameLayout
android:id="#+id/fragment2"
android:layout_weight="5"
android:layout_width="match_parent"
android:layout_height="wrap_content"></FrameLayout>
</LinearLayout>
Fragment3.xml :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<SeekBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:visibility="visible" />
</RelativeLayout>
and this happen when i display fragment 3 which have seekbar
if i display fragment 3 first then any TextView can't display
1) Just update main.xml for weight sum
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_height="wrap_content"
android:text="fragment2"/>
<Button

The fragment shows up by default but I wanted it to be hidden/invisible until I click this button. The problem that I am experiencing is that when I click this button, the fragment won't show up. I'm a complete beginner when it comes to fragments.
My codes in my Main Activity:
package com.example.julian.tutorial_fragment;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity implements TopSectionFragment.TopSectionListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
View frag = findViewById(R.id.fragment3);
frag.setVisibility(View.GONE);
}
//This gets called by the TopFragment when the user clicks the button
#Override
public void createMeme(String top, String bottom) {
BottomPictureFragment bottomFragment = (BottomPictureFragment)getSupportFragmentManager().findFragmentById(R.id.fragment2);
bottomFragment.setMemeText(top, bottom);
}
//this is the onButtonClick
public void sample(View view) {
android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
android.support.v4.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Fragment_Search hello = new Fragment_Search();
fragmentTransaction.add(R.id.fragment3, hello, "HELLO");
fragmentTransaction.commit();
}
}
My codes in Fragment_Search:
package com.example.julian.tutorial_fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;

change your sample function and add this
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.your_layout, new Fragment_Search())
.addToBackStack(null)
.commit();
Basically i have BottomNavigationView activity in that there are 3 fragments (tab1,tab2,tab3) which contain 3 webviews, what i actually wanna to do is while scrolling down the webview my actionbar should hide, likegetSupportActionBar().hide(); i know already there are answers in the stack overflow for the same question, but i don't know what to do in my case, because i am a beginner in android development
here is my activity_main.xml

This is my first fragment (fragment_tab1)

</FrameLayout>
<WebView

This is my java code for tab1
package com.hackerinside.jaisonjoseph.polysocial;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.MotionEvent;

import android.webkit.WebView;
import android.widget.FrameLayout;

/**

*/
public class tab1 extends Fragment {
public ProgressBar bar;
public FrameLayout frameLayout;
public tab1() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_tab1, null);
frameLayout=(FrameLayout) rootView.findViewById(R.id.frame1);
bar=(ProgressBar)rootView.findViewById(R.id.progressBar1);
bar.setMax(100);
final WebView view=(WebView) rootView.findViewById(R.id.webview);
view.loadUrl("http://facebook.com");
view.getSettings().setJavaScriptEnabled(true);
view.setWebViewClient(new MyWebViewClient());
view.setWebChromeClient(new WebChromeClient(){
public void onProgressChanged(WebView view1,int progress){
frameLayout.setVisibility(View.VISIBLE);
bar.setProgress(progress);
if (progress==100){
frameLayout.setVisibility(View.GONE);
}
super.onProgressChanged(view1,progress);
}
});
view.getSettings().setBuiltInZoomControls(true);
view.getSettings().setDisplayZoomControls(false);
bar.setProgress(0);
return rootView;
}
}
Here is a sample idea of implementation.
boolean isShowing;
//oncraete code is here
WebView mScrollView = (WebView) findViewById(R.id.scrollView);
mScrollView.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
#Override
public void onScrollChanged() {
float mfloat = mScrollView.getScrollY();
if (mfloat >= tToolbar.getHeight() && isShowing) {
toolbarAnimateHide();
} else if (mfloat == 0 && !isShowing) {
toolbarAnimateShow(0);
}
}
});
private void toolbarAnimateShow(final int verticalOffset) {
isShowing = true;
//tToolbar is your view(any view)
// add getSupportActionBar().hide() this code here to hide actionbar
// remove below code or comment
tToolbar.animate()
.translationY(0)
.setInterpolator(new LinearInterpolator())
.setDuration(180)
.setListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationStart(Animator animation) {
toolbarSetElevation(verticalOffset == 0 ? 0 : TOOLBAR_ELEVATION);
}
});
}
private void toolbarAnimateHide() {
isShowing = false;
// add getSupportActionBar().show() this code here to showactionbar
// remove below code or comment
//tToolbar is your view(any view)
tToolbar.animate()
.translationY(-tToolbar.getHeight())
.setInterpolator(new LinearInterpolator())
.setDuration(180)
.setListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
toolbarSetElevation(0);
}
});
}
I just want to know if this is possible since first. I have created a custom listView based on the tutorial I read from Sai Geetha. Well it works perfectly on my app except that it needs to extend ListActivity instead of FragmentActivity. Now I'm having a hard time configuring and adding a dialog for this since I need to apply a fragment dialog and I can't use the getFragmentManager() since I'm not working with the FragmentActivity. Is there's another way I can do to work on this without sacrificing the ListActivity? Thanks!
Here's my code so far

You can use ListFragment inside FragmentActivity instead of using a ListActivity.
I have 2 buttons in my xml file, onclicklistener open new popup.why this eror? can help me??

Can anyone help me know the reason for this problem and how do I solve it. I am a newbie to Android.
Thanks

I have 3 buttons in total. And it seemed that, if I don't press the first button, and instead second or third button right after I startup, my application will forcestop.

Please help me out!
You've placed initialization of buttons 2 and 3 inside the first button's onClickListener(), means they won't be initialized before you click the first button. Fix your code.
this is the format.
public class Part1 extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button a = (Button) findViewById(R.id.Disclaimer);
a.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent b = new Intent(getBaseContext(), Part2.class);
Part1.this.startActivity(b);
}
});
final Button c = (Button) findViewById(R.id.Orientation);
c.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent d = new Intent(getBaseContext(), Part3.class);
Part1.this.startActivity(d);
}
});
final Button e = (Button) findViewById(R.id.Course);
e.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent f = new Intent(getBaseContext(), Part4.class);
Part1.this.startActivity(f);
}
});
}
}
