I have three buttons in one activity.when each of the button is clicked ,different layout should be shown with in the same activity.for example if first button is clicked,edit boxes and button should be shown.if second buttojn is clicked listview should be shown etc..
Define different layout files for each layout.
Then after each click event have the intent call this particular activity recalled.
Have setContentView() called conditionally ie determining the particular clickevent and vice versa.
This you can do if you want complete activity to be layuot in diffrent manner. Otherwise if you want some widgets to be displayed on button click then it is pretty easy to show them on click event.
You might wanna consider a "TabWidget" for this. It actually does what you need.
A sample tutorial here.
Why don't you just include the all the layout elements in your single layout, then use the setVisibility attribute to turn them on and off, depending on which button is pressed.
Something like this pseudo code:
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
view1.setVisibility(View.GONE);
view2.setVisibility(View.GONE);
view2.setVisibility(View.VISIBLE);
}
});
button2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
view1.setVisibility(View.VISIBLE);
view2.setVisibility(View.GONE);
view2.setVisibility(View.GONE);
}
});

im trying to create a listView, that has an Button item on it.
I want to make this button clickable, so I did something like this code in Adapter, getView:
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("_myButton_Log", "ShowOnClick");
}
});
And now im trying to change the visibility parameter for my textView:
TextView myDesc = row.findViewById(R.id.my_desc);
myDesc.setVisibility(convertView.GONE);
I want to show this textView in only one row, after click this button.
Now I make that, the button is clickable for each rows but as you can see it's show only the Log. Im a newbie in the ListViews and buttons on it and im trying to get knowledge how to make it work, but for now I cannot find any help...
So im begging here for some help! :)
Anyway if you want me to use the OnItemClickListener it's not possible because im using it for another way.
Ok I found out an response for my question.
Everyone with this problem - just need to make a simple action for a button in list view in your adapter like:
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TextView myPrice = row.findViewById(R.id.price);
Button myButton = row.findViewById(R.id.button);
myPrice.setVisibility(convertView.VISIBLE);
myButton.setVisibility(convertView.GONE);
}
});
I'm trying to do something like this:
When I go to this activity I have what is in black and some objects like EditText boxes.
Once I press the button I want those EditBoxes an other stuff that is up there to stay visible but unable to be edited (that's easy to do from code overriding onClick).
But at the same time I also want to load some layout down inside the same activity (from an xml) and change the button function to act over the objects of the new layout.
Could anyone give me an idea on how to do this two things staying in the same activity?
Update:
public void createButton(){
create_button.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
editText1.setEnabled(false);
editText2.setEnabled(false);
hidden_layout.setVisibility(View.VISIBLE);
create_button.setText("New text");
}
});
}
On the first click I want the button to do that. But once it's pressed I want it to do another thing. How could I do that?
(that's easy to do from code overriding onClick).
Actually I would recommend enable or disable which is easier to trace by using
view.setEnabled(bool);
as for the other question I'd recommend adding the layout from the start with setting visibility to GONE and when needed set the visibility to VISIBLE
view.setVisibility(View.VISIBLE);
view.setVisibility(View.GONE);
Ok, I've realized it was a dumb question, just add a flag an edit it:
public void createButton(){
create_button.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!button_pressed) {
editText1.setEnabled(false);
edittext2.setEnabled(false);
hidden_layout.setVisibility(View.VISIBLE);
create_button.setText("New text");
button_pressed=true;
}
else{
create_button.setText("Second click");
create_button.setEnabled(false);
}
}
});
}
}
I have a set of buttons and views displayed on the screen. At some point, I would like to be able to interact only with one of them and block all the others.
And I need to retain all the listeners to restore theirs behaviors later.
Any ideas?
Thanks!
For disabling buttons, when you clicking on a specific button/view, disable other buttons/views in the specific onClickListener like
//button1 onClickListener
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
button2.setClickable(false); //disable button2
view1.setClickable(false); //disable view1
}
});
likewise for all other buttons and views, then you may enable those by calling
button2.setClickable(true);
view1.setClickable(true);
By default, there is a checkedbox in CheckedTextView, but now I want to replace it by an button.
I have tried to setCheckMarkDrawable which does exactly what I want it look like.
But now the problem is how can I add a listener to this. I want this button to remove current item in the ListView. How can I achieve this?
You could set your button by calling a ressource id like that:
setCheckMarkDrawable (R.id.myListButton);
Then set your listener on that button with:
(Button)findViewById(R.id.myListButton)
.setOnclickListener(new onClickListener()
{
public void onClick(View v)
{
//Do somethting here
}
});
I want to create an application based on quiz which consists of 14 questions.
Can anyone tell me how do I need to go from one question to another by clicking on next button.If I use an Intent then I am afraid that I will be creating 14 Activities :(
I don't think that is the programmatic procedure too.
You can stay in the same Activity and keep track of the question.
You might want to use a TextSwitcher to add a fade in/fade out animation when swapping the question's text.
You could have the button click just update the questions text to be the next question.
nextButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
questionTextView.setText(questionTwo);
}
});
#Vivek you can use view flipper

Change the text of your textviews where the questions are.
#Override
protected void onCreate(Bundle savedInstanceState) {
Button nextButton = (Button) findViewById(R.id.yourButtonId);
TextView questionTextView = (TextView) findViewById(R.id.yourTextViewId);
nextButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
questionTextView.setText("Your Next Question");
}
});
}
A Fragment is a piece of an application's user interface or behavior that can be placed in an Activity.
Has its own lifecycle;
Receives its own input events;
Can be added or removed while the activity is running;
Believe me that is the best method. I have been introduced to fragments having an application with quotes. The list of the quotes in left and the quotes that were changing on left when an author have been selected.
I'm using android.widget.ViewFlipper that contains views where one view contains TextView (question) and "input control" for answer (selectboxes, date/time widget, radiogroup, etc).
