Android Build an Interactive Story App The Rest of the Story Finishing an Activity

help stuck on this question

The code below has been modified to add a "relaunch" button. In the onClick() method for this button, finish this current Activity so that the previous Activity is resumed.

LandingActivity.java
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class LandingActivity extends AppCompatActivity {

    public Button relaunchButton;

    // Some previous code omitted for brevity

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_landing);

        // Some previous code omitted for brevity

        relaunchButton = (Button)findViewById(R.id.relaunchButton);
        relaunchButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Add your code here!
              mRelaunchButton = (Button)findViewById(R.id.relaunchButton);
        mRelaunchButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();   
            }
        });
    }
}

Hi Shorai You're almost there. I actually do not know why you're repeating some of the code here:

 relaunchButton = (Button)findViewById(R.id.relaunchButton);
 relaunchButton.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
         // Add your code here!
         mRelaunchButton = (Button)findViewById(R.id.relaunchButton);  // Duplicated line
         mRelaunchButton.setOnClickListener(new View.OnClickListener() {  //Duplicated line
            @Override  // Duplicated line
            public void onClick(View v) {  // Duplicated line
                finish();   
            }
        });

Under "// Add your code here", you just need to add what action you want to be performed when the user clicks on the Relaunch button. The instructions say you want to finish the activity. If you remove the duplicated lines, you'll be good to go.

Hope that helps :)

thanks a lot, got it

You're welcome :)
