Im working on a school project and it's my first time on android development. I've searched the whole web but couldn't find any answers to my problem. I have a list of images and i would like to put them on one screen and the user would be able to navigate through these images without changing the whole screen. Also Im trying to put an AutoComplete search box to call any image from the list on the same screen. I tried to use viewFlipper method but did not work out. Is there any other way to do it?
You could add an onClick listener to the ImageView. Something like this:
ImageView imgFavorite = (ImageView) findViewById(R.id.favorite_icon);
imgFavorite.setClickable(true);
imgFavorite.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//Change the image here.
}
});

I'm developing an app. It has one Imageview and one button. I want that when user click on the button, everytime the Imageview loads some random image from my Image hosting website.
You should use a ClickListener for your button that when clicked, loads an image to your view. For image loading there are several libs to choose from, you can use glide for example:
myButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ImageView imageView = (ImageView) findViewById(R.id.my_image_view);
GlideApp.with(this).load("your_url_here").into(imageView);
}
});
So whenever you click your button an image gets loaded. Here is github link to library: https://github.com/bumptech/glide
P.S.: When asking questions remember to put as much information as you can so people don't call you on being lazy or something else.
I am trying to attempt the below :
What i am trying to do is whenever a user click on a button, it will add a image to the layout(which the user can scale and move to any position within the layout). The user can repeat this process hence if the user click 6 times on the button, there should be 6 image in the layout.
i have google around, looking for some sample but ain't sure if its the correct one to use. maybe i did not use the correct keyword to search. So far i have seen is endless adapter and RecyclerView but both seen to be mainly for "ListView" type.
Anyone can suggest or share a link/example that i can read up and learn from? It will be a great help.
If you want to add image on button click set on-click listener on it. You need to get how many time the user have clicked the button.
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//get adapter and view
//get image to add
addImage(i); //to desire view
}
});
I want to create a bottom-to-top-link button in Andorid. I have a ListView with a large amount of data.
For an example have a look at this website. Imagine you scrolled down to the bottom of the webpage and you want to get back to the top of the webpage. To do that, you can click the back-to-top button that is scrolling the page back to the beginning of the document.
In the same way I want that for my ListView in Android. I have searched in Google but I didn't find anything related to that. Could you please help me?
there are several ways to scroll to top of your list
listView.setSelectionAfterHeaderView();
listView.smoothScrollToPosition(0);
listview.setSelection(0);
myFAB.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
myScrollView.scrollTo(0, 0);
}
});
I am working with android app.I need to access the contents from sqlite to a single xml page which including text and image. How can I add different images for different activities in a single ImageView and TextView? I am new to android development. So please help me and thanks.
You can use following source of code to change image in single image view.
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
imageView.setImageResource(R.drawable.ic_launcher);
}
});
There may be different buttons event, but imageView will be same. So just change drawables inside click event.
I have an image button which says Select city I want to call an android spinner if anyone clicks on that image. Is it possible??
I would recommend you check out the App/Alert Dialogs section of the API Demos application. I think what you are looking for is a dialog with a single choice list.
Or take a look at this:
http://developer.android.com/guide/topics/ui/dialogs.html#AddingAList
This is entirely possible in several ways. One way is to have a spinner whose visibility is GONE. Clicking on the image makes the spinners visibility VISIBLE.
Another choice is to create a dialog that has the spinner and use the selection to do whatever it is you want to do.
There are other options, but that should get you started.
ImageView iv = (ImageView) findViewById(R.id.iv);
iv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mySpinner.performClick();
}
});
