How do i change activity on a button click android

How do i change activity on a button click android - java

I have an ImageButton that when I want it to be pressed to launch a second Activity. The second activity is called "Dust 2" as seen in my android manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="pete.smokesapp" >
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".homepage"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".Dust2"
android:label="#string/title_activity_dust2" >
</activity>
</application>
</manifest>
I tried following a guide online but got me as far as this stage now my app crashed on launch.
package pete.smokesapp;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Toast;
public class homepage extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_homepage);
findViewById(R.id.imgDust2).setOnClickListener((View.OnClickListener) this);
}
public void imgDust2(View view) {
switch (view.getId()){
case R.id.imgDust2:
Toast.makeText(this, "Dust 2 Clicked", Toast.LENGTH_LONG ).show();
break;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_homepage, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
Here is also my main activity, this is the activity with the ImageButton, i am also new to this so sorry if I seem clueless.

There are two methods available in android using which you can go from one Activity to another.
1. Use button.setOnClickListener()
Create a button in xml file.
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
Now set event listener for the button in your .class file
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//set the event you want to perform when button is clicked
//you can go to another activity in your app by creating Intent
Intent intent = new Intent(getApplicationContext, Activity2.class);
startActivity(intent);
}
});
2. Use <android:onClick="goNext">
Put the onClick as the attribute of the button you have created in xml file.
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:onClick="goNext" />
Now in your .class file define an event for that button as,
goNext() {
Intent intent = new Intent(getApplicationContext, Activity2.class);
startActivity(intent);
}

In your first activity do this:
Button button = (Button) findViewById(R.id.imgDust2);
button.setOnClickListener(new View.OnClickListener () {
#Override
public void onClick(View v){
Intent intent = new Intent(v.getContext(), dust2.class);
startActivity(intent);
}
});

Try the following:
Add implements OnClickListener to your class definition: public class homepage extends ActionBarActivity implements OnClickListener
An error will appear and ask you to add unimplemented methods. Do so.
Change findViewById(R.id.imgDust2).setOnClickListener((View.OnClickListener) this); to findViewById(R.id.imgDust2).setOnClickListener(this);
Place the stuff you want to do when the button is clicked into the new method that was added in step 2.

Set onClick to the xml imageView and put the name of the method:
<ImageButton
android:layout_width="350dp"
android:layout_height="150dp"
android:id="#+id/imgDust2"
android:clickable="false"
android:src="#drawable/dust2"
android:layout_above="#+id/imgOverpass"
android:layout_alignLeft="#+id/imgOverpass"
android:layout_alignStart="#+id/imgOverpass"
android:layout_marginBottom="10dp"
android:onClick="imgDust2"/>

AppCompatActivity has it's own toolbar so you need to remove it by using android:theme="#style/AppTheme.NoActionBar" in manifest
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
</activity>
Although if you are not doing much customization in your toolbar then your can also skip creating your own toolbar by removing it from XML and removing it's initialization from java code as well but by doing this , you will lose the feature of collapsing toolbar

Making a splash screen is actually pretty easy.
1. Create drawable
In my case, I created a drawable named splash.xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:opacity="opaque">
<item android:drawable="#color/colorWhite" />
<item>
<bitmap
android:gravity="center"
android:src="#drawable/sensesmart_icon" />
</item>
2. Add drawable to your styles.xml
Here I just added my drawable to styles:
<style name="SplashTheme" parent="AppTheme">
<item name="android:windowBackground">#drawable/splash</item>
</style>
3. Add splash to manifest
You want to actually tell your app that the splash layout should show before the app has loaded:
<activity android:name=".BaseActivity"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme"> <!--Splash screen-->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
4. Set theme on your starting activity
In my case, BaseActivity is the activity which starts my application, so inside my onCreate(), I start with setting my theme:
protected void onCreate(Bundle savedInstanceState) {
setTheme(R.style.AppTheme);
setContentView(R.layout.activity_base);
super.onCreate(savedInstanceState);
}
This is the only thing you need to do. If you use this method, the splash screen doesn't stay for longer than it needs. Your contentView will start as soon as you have loaded your app.
Hope this helps!

}
public void buttonOnClick (View v){
}
}

The problem is that your activities don't contain the methods that you've set for your buttons' android:onClick attribute.
For the layout that the Frontpage activity is using, you can either change btRegister button's android:onClick attribute to android:onClick="onButtonClick" or create a public void bRegister(View v){...} method in that activity.
For the Login activity, the layout has two buttons with their android:onClick attribute set to userReg and userLogin, you can either create those methods in the activity or change both of those attributes values to buttonOnClick.

when i run the application and click on register button my app crashes
and shuts down
It is because this button:
<Button
android:layout_width="108dp"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="Register"
android:id="#+id/btRegister"
android:onClick="bRegister"
android:background="#null"
android:layout_gravity="center_horizontal" />
in your frontpage activity needs a method with signature public void bRegister(View view) in your FrontPage.java class. As you do not have this method, it crashes.
login button doesn't even do anything
The reason is, this button
<Button
android:layout_width="98dp"
android:layout_height="wrap_content"
android:layout_marginTop="50dp"
android:text="Login"
android:id="#+id/btLogin"
android:onClick="bLogin"
android:background="#null"
android:layout_gravity="center_horizontal" />
in your frontpage activity needs a method called public void bLogin(View view) in your Frontpage.java class. Though the method is present, you do not have any code in it, hence it does not do anything.
You need to add proper code in bLogin method so that your login button starts functioning, and even before that add a bRegister method so that your register button starts working.
Hope this helps you.

RuntimeError for activity specified on Android Manifest

I have this problem that just seems strange.
I have this Android View with six buttons and when i click on one of them(the only one with the action defined apart from the exit button), it gives me a RuntimeError.
The Activity is declared on the manifest, and this is why i don't understand my error.
Can someone please help me with this.
I would really appreciate it :)
So here's my code:
package com.example.calendar;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
public class MainActivity extends Activity implements OnClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
View createButton = findViewById(R.id.btn_create);
View deleteButton = findViewById(R.id.btn_delete);
View moveButton = findViewById(R.id.btn_move);
View searchButton = findViewById(R.id.btn_search);
View translateButton = findViewById(R.id.btn_translate);
View exitButton = findViewById(R.id.exit);
createButton.setOnClickListener(this);
deleteButton.setOnClickListener(this);
moveButton.setOnClickListener(this);
searchButton.setOnClickListener(this);
translateButton.setOnClickListener(this);
exitButton.setOnClickListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.btn_create:
Intent i = new Intent(this, CreateAppointment.class);
startActivity(i);
break;
case R.id.exit:
finish();
break;
}
}
}
My layout is like this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:background="#color/background"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="225dp"

android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<TableLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginBottom="2dip"
android:layout_marginTop="2dip"
android:stretchColumns="*" >
<TableRow>
<Button
android:id="#+id/btn_create"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/create" />
<Button
android:id="#+id/btn_viewEdit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/viewEdit" />
</TableRow>
<TableRow>
<Button
android:id="#+id/btn_delete"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/delete" />
<Button
android:id="#+id/btn_move"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/move" />
</TableRow>
<TableRow>
<Button
android:id="#+id/btn_search"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/search" />
<Button
android:id="#+id/btn_translate"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/translate" />
</TableRow>
</TableLayout>
<Button
android:id="#+id/exit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/exit"/>
</LinearLayout>
And the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.calendar"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.calendar.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".CreateAppointment"
android:theme="#android:style/Theme.Dialog"
android:label="#string/create" >
</activity>
</application>
</manifest>

You have to define correctly what kind of views ares using in onCreate()
View createButton = findViewById(R.id.btn_create);
for example:
since you are using a Button:
<Button
android:id="#+id/btn_create"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/create" />
Make the cast as button:
Button createButton = (Button)findViewById(R.id.btn_create);
try this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button createButton = (Button)findViewById(R.id.btn_create);
Button deleteButton = (Button)findViewById(R.id.btn_delete);
Button moveButton = (Button)findViewById(R.id.btn_move);
Button searchButton = (Button)findViewById(R.id.btn_search);
Button translateButton = (Button)findViewById(R.id.btn_translate);
Button exitButton = (Button)findViewById(R.id.exit);
createButton.setOnClickListener(this);
deleteButton.setOnClickListener(this);
moveButton.setOnClickListener(this);
searchButton.setOnClickListener(this);
translateButton.setOnClickListener(this);
exitButton.setOnClickListener(this);
}

Android app hangs

Hey i'm brand new to programming and i need some help,
i'm doing a project for school and it's an android app where the user inputs words to a text field and then those words are used to create a story, like mad libs.

Umm... where are you instantiating your Submit button before trying to set an onClickListener on it? I see where you declare it, but you aren't instantiating it.
Add:
Submit = (Button)findViewById(R.id.button1);
right before
Submit.setOnClickListener(new View.OnClickListener() {
and watch. It's gonna be like magic.
One more thing about coding conventions (style): when you name your instance variables, use the headlessCamelCase convention. Names with CamelCase/InitCaps (first letter of each word capitalized) should only be used when you name your class (the pattern for an object) as opposed to when you refer to an instance of that class (the actual object).
Wrong:
// An instance of Button class
Button Submit;
Right:
// An instance of Button class:
Button submit;
When it comes to compound names (more than one word), headlessCamelCase means you capitalize the first letter of each word, except the first word.
Right:
// An instance of Button class:
Button myVeryElderlyMotherJustSatUponNapoleonsSubmitButton;
