Help me solve my problem. I'm doing the transition between the activity using the startActivity method.
If I press n-times on the button that initiates startActivity, there will be n-transitions to activity. How to make the transition was only one?
You can set the button unclickable when you press it the first time.
The code is:
button.setEnabled(false);

I am using Java and Android Studio. I have one activity with a few options to select from, and once one of them is selected, they click the button that takes them to the next activity. They do the same thing again except this time when the user clicks the button it takes them to a new activity where it displays the results based on the two radio buttons clicked previously. How can I do this?
You can send some variable through intent and onCreate() method of the second activity, you can use that variable to differentiate your functionality.
This video demonstrates the functionality of the radio button: https://youtu.be/zJG9Prn3vZ0
In this video you can know how to pass arguments to another activity: https://youtu.be/OMCctaE66b8
Hope that helps you to solve your problem.
You cannot declare a method inside another method. Put a closing brace after onCreate.
When you are opening a new activity, you are doing it with an Intent. Put the values you want to send (bool clicked) the new activity inside the intent
Suppose I move to another activity from my current one and then I need to go back to previous activity by pressing the back button originally present in the phone along with a home button and menu button. I have disabled my Action Bar and I don't want to enable it. Nor I want to create an icon in my activity that represents back.
Please Help!
to initiate the back operation you can call
super.onBackPressed();
from your activity.
So I have a Button in FirstActivity.java which when you press leads you to a second activity: SecondActivity.java, which has another button BackButton that leads you back to FirstActivity.java. The code in the first activity allows you to change the layout according to different conditions. Is there a way that if the layout of FirstActivity.java is changed, you press the Button to go to the second activity, then when you press the BackButton to go back to FirstActivity.java, the layout changes will be saved in the first activity?
You can use putExtra for send data to SecondActivity, and return data to onActivityResult.
In my Android Project, whenever I go from First Activity to Second, I get an left arrow button followed by the some text in the action bar. That left arrow only comes when I set my First Activity as the hierarchical parent of the Second Activity.
I want to remove that back button and replace it with an icon. I have read other posts for the same question, and so I have already tried the following code in my onCreate() method.
getActionBar().setDisplayHomeAsUpEnabled(false);
But after reaching to the second activity, the app gets crashed.
Please help me out.
Use getSupportActionBar() bar:
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setHomeButtonEnabled(false);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_yourindicator);
In my application i am using tabhost. And to control different activities i am using activity group. I have Activity A from which i am going to activity B. Activity B contains Edit Text, Spinner, Button etc. Now when i scroll the Activity B and press the device Back Button than it does not go to the previous Activity. It goes out of application.
Kindly suggest the answer.
This is the way the Activity lifecycle works for Activity Group. Try using fragments instead of activity group with your tabhost to get your movements. Also, please edit your question title to more accurately reflect the actual question.
