Used to make your EditText a better option than Spinners

ClickToSelectEditText.java

public class ClickToSelectEditText <T> extends AppCompatEditText {
    
    CharSequence mHint;
    
    OnItemSelectedListener<T> onItemSelectedListener;
    ListAdapter mSpinnerAdapter;
    
    public ClickToSelectEditText(Context context) {
        super(context);
        
        mHint = getHint();
    }
    
    public ClickToSelectEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        
        mHint = getHint();
    }
    
    public ClickToSelectEditText(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        
        mHint = getHint();
    }
    
    
    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        setFocusable(false);
        setClickable(true);
    }
    
    public void setAdapter(ListAdapter adapter) {
        mSpinnerAdapter = adapter;
        
        configureOnClickListener();
    }
    
    
    
    
    private void configureOnClickListener() {
        
        setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                AlertDialog.Builder builder = new AlertDialog.Builder(view.getContext());
                builder.setTitle(mHint);
                builder.setAdapter(mSpinnerAdapter, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int selectedIndex) {
                        if (onItemSelectedListener != null) {
                            onItemSelectedListener.onItemSelectedListener((T)mSpinnerAdapter.getItem(selectedIndex), selectedIndex);
                        }
                    }
                });
                builder.setPositiveButton(android.R.string.cancel, null);
                builder.create().show();
            }
        });
    }
    
    public void setOnItemSelectedListener(OnItemSelectedListener<T> onItemSelectedListener) {
        this.onItemSelectedListener = onItemSelectedListener;
    }
    
    public interface OnItemSelectedListener<T> {
        void onItemSelectedListener(T item, int selectedIndex);
    }
}

Usage.java

  
  @InjectView(R.id.signup_text_input_job_category)
  ClickToSelectEditText<JobCategory> editTextJobCategory;
  
  ...

  //Adapter must implement ListAdapter (e.g. extend ArrayAdapter<MyModel>)
  JobCategoryAdapter adapter = new JobCategoryAdapter(getContext(),
  android.R.layout.simple_list_item_1,
  android.R.id.text1,
  mJobCategoryList);

  editTextJobCategory.setAdapter(adapter);
  editTextJobCategory.setOnItemSelectedListener(new ClickToSelectEditText.OnItemSelectedListener<JobCategory>() {
      @Override
      public void onItemSelectedListener(JobCategory item, int selectedIndex) {
          selectedJobCategory = item;
      }
  });

Usage.xml

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <com.your.package.ClickToSelectEditText
        android:id="@+id/signup_text_input_job_category"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/hint_job_category"
        android:drawableRight="@drawable/ic_arrow_down"/>
</android.support.design.widget.TextInputLayout>

You should add also setLongClickable(false) to avoid paste action:

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        setFocusable(false);
        setClickable(true);
        setLongClickable(false);
    }

Nice!

Actually in my case in order to show selected item, I had to modify onItemSelectedListener to be like:

@Override
      public void onItemSelectedListener(JobCategory item, int selectedIndex) {
          editTextJobCategory.setText(item.getSomeText());
      }

Thank you!

JobCategory is it a Pojo class ?

@ihaveafix yes it is
