On Android, how do you switch activities programmatically?

Question

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 wit

Answer 1

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

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);
      }
  });
}
