I need a help with my app, I am creating music app by using listView and adapter,image for main activity
i use imagebutton to go to details activity but when i click on it no thing happen
this is main activity code
package com.example.musicano;
import android.content.Context;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.RelativeLayout;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList<Song> songs=new ArrayList<Song>();
songs.add(new Song("See You Again","Wiz Knalifa"));

ListView listView=(ListView) findViewById(R.id.list);
SongAdapter adapter=new SongAdapter(this,songs);
listView.setAdapter(adapter);
LayoutInflater inflater = getLayoutInflater();
View view= inflater.inflate(R.layout.list_item,listView,false);
ImageButton playMusic = (ImageButton)view.findViewById(R.id.playButton);
playMusic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this,Details.class);
startActivity(intent);
}
});
}
}
and custom adapter code is
package com.example.musicano;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class SongAdapter extends ArrayAdapter<Song> {
public SongAdapter (Activity context, ArrayList<Song>songs){
super(context,0,songs);
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
Song cureentSong=getItem(position);
View listItemView=convertView;
if(listItemView==null){
listItemView= LayoutInflater.from(getContext()).inflate(R.layout.list_item,parent,false);
}
TextView songName=(TextView) listItemView.findViewById(R.id.text_view_song_name);
TextView artistName=(TextView) listItemView.findViewById(R.id.text_view_artist_name);
ImageButton playMusic=(ImageButton) listItemView.findViewById(R.id.playButton);
songName.setText(cureentSong.getSongName());
artistName.setText(cureentSong.getArtistName());
return listItemView;
}
}
and activity_main.xml contain
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"

and list_item layout contain
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:id="#+id/relativlayout"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"

</LinearLayout>
<ImageButton
android:id="#+id/playButton"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/play"
android:layout_marginRight="26dp"
android:layout_marginTop="26dp"
/>
</RelativeLayout>
that is it
What is reason for doing view.findViewById, the button is in MainActivity itself right?
Try the following and check if this works?
Hope this helps
ImageButton playMusic = (ImageButton)findViewById(R.id.playButton);
playMusic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this,Details.class);
startActivity(intent);
}
});
If the image button is in list_item_layout then add the click listener in the adapter instead of MainActivity. Then it should work.
Add the following in your adapter code:
ImageButton playMusic=(ImageButton) listItemView.findViewById(R.id.playButton);
playMusic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(mContext,Details.class);
intent .addFlags(FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(intent);
}
});
Use the context used in your Adapters constructor create a instance
private Context mContext;
and inside your adapter's constructor assign it to context as shown below:
this.mContext = context
Hope this helps.
I want to use bottom navigation bar in my existing android app but the problem is all screen are activity ,is it possible to load activity without hiding the bottom navigation bar.
example:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

this is my base activity,

I have solved this problem in following way:
1.Create one BaseActivity with bottom nav bar.
package com.example.apple.bottomnavbarwithactivity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class BaseActivity extends AppCompatActivity {
RadioGroup radioGroup1;
RadioButton deals;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
radioGroup1=(RadioGroup)findViewById(R.id.radioGroup1);
deals = (RadioButton)findViewById(R.id.deals);
radioGroup1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
{
#Override
public void onCheckedChanged(RadioGroup group, int checkedId)
{
Intent in;
Log.i("matching", "matching inside1 bro" + checkedId);
switch (checkedId)
{
case R.id.matching:
Log.i("matching", "matching inside1 matching" + checkedId);
in=new Intent(getBaseContext(),MatchingActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.watchList:
Log.i("matching", "matching inside1 watchlistAdapter" + checkedId);
in = new Intent(getBaseContext(), WatchlistActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.rates:
Log.i("matching", "matching inside1 rate" + checkedId);
in = new Intent(getBaseContext(),RatesActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.listing:
Log.i("matching", "matching inside1 listing" + checkedId);
in = new Intent(getBaseContext(), ListingActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.deals:
Log.i("matching", "matching inside1 deals" + checkedId);
in = new Intent(getBaseContext(), DealsActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
default:
break;
}
}
});
}
}

2.extend BaseActivity in all the activity that you want to open on bottom nav click and also need to inflate the activity layouts
For example, I have created five sample activity.
i] MatchingActivity.
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
//extends our custom BaseActivity
public class MatchingActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_matching);
//dynamically include the current activity layout into baseActivity layout.now all the view of baseactivity is accessible in current activity.
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_matching, null);
dynamicContent.addView(wizard);
//get the reference of RadioGroup.
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.matching);
// Change the corresponding icon and text color on nav button click.
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_matching_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
ii]WatchlistActivity
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class WatchlistActivity extends AppCompatActivity {
LinearLayout dynamicContent,bottonNavBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_watchlist1);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_watchlist1, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.watchList);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.favourite_heart_selected, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
iii]RatesActivity
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class RatesActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.activity_rates);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_rates, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.rates);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_rate_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
iv] ListingActivity
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class ListingActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_listing);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_listing, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.listing);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_listing_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
v] DealsActivity
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class DealsActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_deals);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_deals, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.deals);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_deals_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
Note: make sure that you handle back press properly.I have not written any code for back press.
With Activity, you have to declare and init that BottomBar each time you load that activity.
With your problem, my answer is NO.
Btw, you can use Fragment which helps you solve this pretty good.
Time to learn something new, bro.
EDIT
You bring Fragment inside only 1 Activity. And let BottomBar inside Activity while all others view and data set inside Fragment.
Just try it!
i have a few pages realized with a PagerAdapter and one layout-file in the folder "res/layout" and one layout-file in "res/layout-land". Each Layout has two ImageButtons, where:
imageButton1 in portrait has the same ID as the imageButton1 in landscape.
imageButton2 in portrait has the same ID as the imageButton2 in landscape.
I have assigned an onClickListener to imageButton1 button which:
takes the images from the ImageButtons
rescales the Images to fit/fill the ImageButtons
and reassigns the rescaled pictures to the ImageButtons.
But whenever i change the orientation in my emulator the images/pictures in these buttons get lost, or change to the images specified in the layout-file originally and dont refresh to the pictures i assigned to the buttons programmatically.
PS (for example): i assigned in onCreate a listener to button1 and that listener works for this button both in portrait and also in landscape. So these are not seperated buttons!!!!!!
Question: how can i make it work that the images are not lost when changing orientation?
thx for any help in advance!
here is my code:
layout-portrait file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

UPDATE:
i did it like this now (example for saving and restoring Bitmap of imageButton1):
#Override
protected void onSaveInstanceState(Bundle outState)
{
// TODO Auto-generated method stub
super.onSaveInstanceState(outState);
BitmapDrawable draw=(BitmapDrawable)((ImageButton)pages.get(0).findViewById(R.id.imageButton1)).getDrawable();
Bitmap bmp = ((BitmapDrawable)draw).getBitmap();
outState.putParcelable("IMG_OF_BUTTON1", bmp);
super.onSaveInstanceState(outState);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onRestoreInstanceState(savedInstanceState);
Bitmap bmp= savedInstanceState.getParcelable("IMG_OF_BUTTON1");
((ImageButton)pages.get(0).findViewById(R.id.imageButton1)).setImageBitmap(bmp);
}
i have a few pages realized with a PagerAdapter and within that some LinearLayouts, which have some ImageButtons.
My Issue:
i want to get the imagebuttons from all the layouts from my pages on app-start, get the size of them and to resize the images to fill the imagebuttons. Gettting the images and rescaling them works fine, BUT if i do this at the function "onWindowFocusChanged" it only works on the first two pages. The ImageButtons on the third page until the last page are just gone. I assume the problem is that either these pages OR the linear-layouts OR the ImageButtons on these pages are not drawn yet so that it doesnt work.
To prove this i assigned a on-click listener to one of these buttons and do my calculation then and not already at onWindowFocusChanged. This has the same effect, BUT if i click the button after i have wiped over all pages it works on all pages.
Question: how can i make it work on startup for all pages OR without having to wipe over all pages first?
thx for any help in advance!

I have two activities and the first is generating properly however the second is not. only the first element in the xml file will show up. here is my xml file:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/alternateActivity"
android:shadowColor="#color/shadowColor"></TextView>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/oldActivityButton"
android:text="#string/oldActivityButton"></Button>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/changeText"
android:text="#string/changeTextButton"></Button>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/originalText"
android:id="#+id/textToChange"></TextView>
</LinearLayout>
and here is my activity that corresponds:
package fsg.dev.activitytest;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class newActivity extends Activity {
private Button oldActivityButton;
private Button changeText;
private TextView textToChange;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.alternate);
oldActivityButton = (Button) findViewById(R.id.oldActivityButton);
changeText = (Button) findViewById(R.id.changeText);
textToChange = (TextView) findViewById(R.id.textToChange);
oldActivityButton.setOnClickListener(new OnClickListener(){
public void onClick(View view){
changeActivity();
}
});
changeText.setOnClickListener(new OnClickListener(){
public void onClick(View view){
changeText();
}
});
}
private void changeActivity(){
Intent i = new Intent(this, activityTest.class);
startActivity(i);
}
private void changeText(){
if(textToChange.equals(R.string.originalText)){
textToChange.setText(R.string.newText);
} else {
textToChange.setText(R.string.originalText);
}
}
}
has anyone else seen this problem? or know of a way to fix it?
Try to add android:orientation="vertical" to your LinearLayout
replace
Intent i = new Intent(this, activityTest.class);
by
Intent i = new Intent().setClass(this, activityTest.class);
