Android: Dynamically Starting An Activity

I would like to dynamically start an activity based on the previous activity's input. I have input a string through the previous activity, the only thing is this specific code thro

Solution 1:

The ComponentName object does just that:

Stringactivity= intent.getStringExtra(MainActivity.TEST_TYPE);
Intentintent=newIntent(this, newComponentName(this, activity));
startActivity(intent);

That's assuming this is an instance of Activity. (for a Fragment, use getActivity(), obv.)

Solution 2:

I have a class on here:

com.yasinkacmaz.newproject.activity.ProfileActivity

My test string like that:

"com.yasinkacmaz.newproject.activity.ProfileActivity"

And it working good:

publicclassEasyCountDownextendsAppCompatActivity {
    finalActivitythisActivity=this;
    private Intent previousIntent,nextIntent;

     @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_layout);

        previousIntent = getIntent();
        Stringtest= previousIntent.getStringExtra(MainActivity.TEST_TYPE);
        finalStringactivity= test;
        Classnewclass=null;

        try {
          newclass = Class.forName(activity);
        } catch (ClassNotFoundException c) {
            c.printStackTrace();
        }

        if(newclasss != null) {
            nextIntent = newIntent(thisActivity, newclass);
            startActivity(nextIntent);
        } else {
            Toast.makeText(getApplicationContext(),"new class null",Toast.LENGTH_SHORT).show();
        }
    }
} 

Dont forget you can use switch case or etc., because in this way you can get ClassNotFoundException and your intent will be null.
