'On Android, how do you switch activities programmatically?

It seems like every example I can find of switching between activities involves creating an Intent and passing in the context of a View via an OnClickListener associated with a button.

But what if you just decide you need to switch activities? In my case, a preference value is causing an Activity switch.

How do you create an Intent that can cause an Activity switch without an associated OnClickListener?

android android-activity

This should do it for you:

Intent myIntent = new Intent(this, MyActivityName.class);
startActivity(myIntent);

You can call that from anywhere in your current activity.

Solution 2:^[2]

It depends where you want to start the new activity in the code. You need the access to a Context reference to start a new activity( For example: onPostExecute in AsyncTask). Please have a look at this.

Even though it is basically this.

 Intent myIntent = new Intent(this, ActivityName.class);
 startActivity(myIntent);

It can be something like this as well

Intent myIntent = new Intent(context, ActivityName.class);
context.startActivity(myIntent);

I have the shortest Version

startActivity(new Intent(CurrentActivity.this,ActivityYouWantToOpen.class));

Solution 4:^[4]

startActivity (new Intent (Thisactivity.this, Nextactivity.class));

Don't forget to add activity to your manifest

<Activity android:name=".NextActivity>

Solution 5:^[5]

when ever u want to switch activity . u can call these code .

Intent intent = new Intent(this, MyActivity.class);
startActivity(intent);

You can write this code in PreferenceChangeListener.

Solution 6:^[6]

You can create intent in the main activity like this

Intent intent = new Intent(FirstActivity.this, second.class);
startActivity(intent);

If you are waiting for result from the second then you should use

StartActivityforresult(intent,request code).

Request code can be any integer.

Use PreferenceChangeListener :)

Firstly you need to create UI for a button by using layout intro_activity_1.XML file. After that set id for button group using android:id="@+id/button"

Example:

intro_activity_1.xml

<Button    android:id="@+id/button"    
android:layout_width="wrap_content"    
android:layout_height="wrap_content"    
android:layout_weight="1"    
android:background="@android:color/transparent"    
android:text="NEXT" />

Now change your java class of first activity. In this example, we change java file of IntroActivity1.java

Example:

IntroActivity1.java

//header, import and package data


public class IntroActivity1 extends AppCompatActivity {


    Button next_btn;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.intro_activity_1); 

           next_btn=(Button)findViewById(R.id.button);//button class

           next_btn.setOnClickListener(new View.OnClickListener(){
   public void onClick(View arg0){
       //Start new activity class
              Intent myIntent=new Intent(IntroActivity1.this,IntroActivity2.class);
             startActivity(myIntent);
      }
  });
}
