Important Note:<\/strong><\/span> ArrayAdapter is an implementation of BaseAdapter so if we need to create a\u00a0custom list view or \u00a0a grid view \u00a0then we have to\u00a0create our own\u00a0custom adapter and extend ArrayAdapter in that custom class. By doing this\u00a0we can override \u00a0all the function\u2019s of BaseAdapter in our custom adapter.<\/p>\n Here is code of ArrayAdapter in Android:<\/strong><\/span><\/p>\n In the above code snippet is the implementation of a ArrayAdapter. Below is the description of all the parameters used for the implementation of a ArrayAdapter to show a list of elements in a list view or in a spinner.<\/p>\n Parameters used in ArrayAdapter:<\/strong><\/span><\/span><\/p>\n Lets discuss parameter in ArrayAdapter class:<\/p>\n The first parameter is used to pass the context means the reference of current class. Here this is a keyword used to show the current class reference. We can also use getApplicationContext(), getActivity() in the place of this keyword. getApplicationContext() is used in a Activity and getActivity() is used in\u00a0 a Fragment.<\/p>\n Below is the example code in which we set the current class reference in a adapter.<\/p>\n The second parameter is resource id used to set the layout(xml file) for list items in which you have a text view.<\/p>\n Below is the example code in which we set the layout.<\/p>\n The third parameter is textViewResourceId which is used to set the id of TextView where you want to display the actual text.<\/p>\n Below is the example code in which we set the id(identity) of a text view.<\/p>\n The fourth parameter is an array of objects, used to set the array of elements in the textView. We can set the object of array or array list here.<\/p>\n Below is the example code in which we set the Animal array in adapter to display the Animal name\u2019s list.<\/p>\n Example 1:<\/strong><\/span> Below is the example, in which we displays a list of animal names in a list view using simple array adapter. Below is the final output and code:<\/p>\n Download Code<\/a> ? <\/a><\/p>\n Step 2:<\/strong><\/span> Now open app -> res -> layout ->\u00a0xml (or) activity_main.xml<\/strong>\u00a0and add following code :<\/p>\n Step 3:<\/strong><\/span> Create a new Activity activity_list_view.xml and add the below code<\/p>\n Step 4:<\/strong><\/span> Now Open app -> java -> package ->\u00a0MainActivity.java and add the below code. Here we will use ArrayAdapter to display the items in Listview.<\/p>\n Output:<\/strong><\/span><\/p>\n Now run the App in Emulator and you will see the below output:<\/p>\n Example 2: <\/strong><\/span>Below is the example, In which we display a list of Animal\u2019s name in spinner using ArrayAadapter. Below is the final output and code:<\/p>\n Download Code<\/a> ? <\/a><\/p>\n Step 2:<\/strong><\/span> Now open app -> res -> layout -> activity_main.xml (or) main.xml\u00a0and add following code:<\/p>\n Step 3:<\/strong><\/span> Now create a new Activity simple_spinner_item.xml and add the below code:<\/p>\n Step 4:<\/strong><\/span> Now open app -> java -> package ->\u00a0MainActivity.java and add the following code<\/p>\n Output:<\/strong><\/span><\/p>\n Now run the App in Emulator \/ AVD and you will see the animals name listed in a Spinner<\/p>\n In android, An adapter is a bridge between UI component and data source that helps us to fill data in UI component. It holds the data and send the data to adapter view then view can takes the data from the adapter view and shows the data on different views like listview, gridview, spinner etc. … Continue reading ArrayAdapter Tutorial With Example In Android Studio<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":607,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[62,1],"tags":[],"class_list":["post-600","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-adapter","category-archieve"],"acf":[],"psp_head":"ArrayAdapter(Context context, int resource, int textViewResourceId, T[] objects)\r\n<\/pre>\n
