The first button works fine, but when I click to the second, nothing happens. I'm not getting any errors, I can't see what's wrong.
Sounds.java
package com.andrew.finnandjake;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Sounds extends Activity {
private SoundManager mSoundManager;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(1, R.raw.finn_whatthejugisthat);
Button b1 = (Button)findViewById(R.id.Button1);
b1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mSoundManager.playSound(1);
}
});
}
public void onCreate1(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(2, R.raw.jake_dancingwithbabes);
Button b2 = (Button)findViewById(R.id.Button2);
b2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mSoundManager.playSound(2);
}
});
}
}
You can't randomly create a method like you're doing with onCreate1, it's never executed by you or by your Activity.
This is all you need:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mSoundManager = new SoundManager();
mSoundManager.initSounds(this);
mSoundManager.addSound(1, R.raw.finn_whatthejugisthat);
mSoundManager.addSound(2, R.raw.jake_dancingwithbabes);
Button b1 = (Button)findViewById(R.id.Button1);
b1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mSoundManager.playSound(1);
}
});
Button b2 = (Button)findViewById(R.id.Button2);
b2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mSoundManager.playSound(2);
}
});
}
You aren't assigning the onclick listener inside the actual OnCreate. This should work:
package com.andrew.finnandjake;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Sounds extends Activity {
private SoundManager mSoundManager;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(1, R.raw.finn_whatthejugisthat);
mSoundManager.addSound(2, R.raw.jake_dancingwithbabes);
Button b1 = (Button)findViewById(R.id.Button1);
b1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mSoundManager.playSound(1);
}
});
Button b2 = (Button)findViewById(R.id.Button2);
b2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mSoundManager.playSound(2);
}
});
}

It loads the site but only when it's not in the Action Listener.
Even if I load the url way down in the onCreate method it works.
I already checked if the Webview is invisible, the button listener works also.
The problem began after a few hours of coding other things
WebView wbvCheckURL;
Button btnSearch;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wbvCheckURL = findViewById(R.id.wbvCheckURL);
btnSearch = findViewById(R.id.btnSearch);
wbvCheckURL.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
...
}
#Override
public void onReceivedTitle(WebView view, String title) {
...
}
});
wbvCheckURL.getSettings().setJavaScriptEnabled(true);
wbvCheckURL.setWebViewClient(new WebViewClient());
// When i do it like this it works:
// wbvCheckURL.loadUrl("http://www.google.de");
btnSearch.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
wbvCheckURL.loadUrl("http://www.google.de");
hideKeyboard(v);
LoadCode();
}
});
}
The Solution is to load it in a Thread
Create instance and start the thread:
LoadURL t = new LoadURL();
t.start();
Thread class:
class LoadURL extends Thread {
public void run() {
Classname.wbvCheckURL.post(new Runnable() {
public void run() {
Classname.wbvCheckURL.loadUrl("http://www.google.de");
}
});
}
you can try mine. Mine is another kind of webview with Drawer Layout. Hope you get the idea on how to insert the webview.

I encountered an issue and couldn't resolve in Android Studio. The setOnClickListener remains red and doesn't work unless I get rid of my "loseStarter1" button name.
Note: Starter1 is a button, I'm trying to make it disappear when clicked by the user. My real code starts when I introduce the loseStarter1 button.
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class game1 extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game1);
}
Button loseStarter1;
loseStarter1 = (Button) findViewById(R.id.Starter1);
loseStarter1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loseStarter1.setVisibility(View.GONE);
}
})
}
Much appreciated.
You're missing a semicolon to end the new View.OnClickListener() { ... statement as well as that block not being inside of a method.
Not only move this code into the onCreate method, make sure you end it with a semicolon.
loseStarter1 = (Button) findViewById(R.id.Starter1);
loseStarter1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loseStarter1.setVisibility(View.GONE);
}
}); // Add the semicolon here
It should look like this:
public class game1 extends AppCompatActivity {
Button loseStarter1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game1);
loseStarter1 = (Button) findViewById(R.id.Starter1);
loseStarter1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loseStarter1.setVisibility(View.GONE);
}
}); //added semicolon
} // ends onCreate method
} // ends class
Your Button variable declaration and OnClickListener initialization is outside of the onCreate() method. Use the following code:
package com.cutting_edge_tech.mentalenhancementapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class game1 extends AppCompatActivity {
private Button loseStarter1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game1);
loseStarter1 = (Button) findViewById(R.id.Starter1);
loseStarter1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loseStarter1.setVisibility(View.GONE);
}
});
}
}
Move below code inside onCreate()
loseStarter1 = (Button) findViewById(R.id.Starter1);
loseStarter1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loseStarter1.setVisibility(View.GONE);
}
});
This is how i do it.
1) first make the class implement the interface View.OnClickListener, this let you handle the button clic event:
public class game1 extends AppCompatActivity implements View.OnClickListener;
2) second create the interface method to handle event.
#Override
public void onClick(View view)
{
if(view.getId()==R.id.Starter1)
{
view.setVisibility(View.GONE);
}
}
3) OnCreate methods is the best way to find objects and set properties.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game1);
loseStarter1= (Button) findViewById(R.id.Starter1);
if(loseStarter1!=null){
loseStarter1.setOnClickListener(this);
}
}
all code :
package com.cutting_edge_tech.mentalenhancementapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class game1 extends AppCompatActivity implements View.OnClickListener {
private Button loseStarter1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game1);
loseStarter1 = (Button) findViewById(R.id.Starter1);
if(loseStarter1!=null){
loseStarter1.setOnClickListener(this);
}
}
#Override
public void onClick(View view)
{
if(view.getId()==R.id.Starter1)
{
view.setVisibility(View.GONE);
}
}
}
Advice:
Rename class to Game1.
Android app, i wrote to test image button doesn't work. I have created a image button and implement an event listener for that button. What's wrong with this source code?
import android.view.View;
import android.view.View.OnClickListener;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageButton;
import android.widget.Toast;
public class ImageButtonTestApp extends Activity {
ImageButton imageButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void eventListenerOnButton() {
imageButton = (ImageButton) findViewById(R.id.imageButton1);
imageButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(ImageButtonTestApp.this, "ImageButton is clicked!", Toast.LENGTH_SHORT).show();
}
});
}
}
u have written setOnClickListener in different method but u didnot call that method any where call that method in oncreate.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
eventListenerOnButton();
}
try this one,
Try it
imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(ImageButtonTestApp.this, "ImageButton is clicked!", Toast.LENGTH_SHORT).show();
}
});
I have a page that has two buttons to "two" other pages, the thing is, button 1 and button 2 lead to a second page, thought button 1 should lead to the first page and button 2 should lead to the second page, here is the java file, I don't know how to put it!
ActiveMain.java
package com.d.di;
import android.app.Activity;
import android.content.Context;

public class MainActivity extends Activity {
Button button1;
Button button2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton();
}
public void addListenerOnButton() {
final Context context = this;
button1 = (Button) findViewById(R.id.abus);
button2 = (Button) findViewById(R.id.weoff);
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, PageOne.class);
startActivity(intent);
}
});
button2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, PageTwo.class);
// you made a mistake here you called the PageOne again here while you should call the second.
startActivity(intent);
}
});
}
}
PageOne.java
package com.d.di;
import android.app.Activity;

import android.widget.Button;
public class PageOne extends Activity {
Button button1;
#Override

}
}
PageTwo

}
}
button1.setOnClickListener(new OnClickListener() {

}
});
button2.setOnClickListener(new OnClickListener() {

mistake here you called the PageOne again here while you should call the second.
startActivity(intent);
}

This is my starting activity. I'm trying to get this button to work but it's been giving me this error.
Line 15 button can not be resolved.
package com.synamegames.giveaway;
import android.view.View.OnClickListener;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class GiveawayActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final Button register = (Button) findViewById(R.id.register);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
}
});
setContentView(R.layout.main);
}
}
Please try this..
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button register = (Button) findViewById(R.id.register);
register.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
}
});
}
The problem is You have defined the Button instances as register in the line final Button register = (Button) findViewById(R.id.register); But you are setting onclick listener to the button instance which is not defined. You should have
register.setOnClickListener(new OnClickListener() {
instead of
button.setOnClickListener(new OnClickListener() {
U can use android:onClick from xml and pass a the view into the .java file
eg:
android:onClick="bactToList"
in java:
public void bactToList(View view){
}
