Android: Get Textview value of Spinner on Button click

Question

I have a Spinner and i am populating it with custom SimpleCursorAdapter . Spinner item layout contains two TextView s, One TextView for item id and it is not visible other is for item name. I want to get this item id on button click event then insert it to Sqlite database. I get the id on setOnItemSelectedListener of Spinner as

companySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

                // Get selected row data to show on screen
                String companyId = ((TextView) view.findViewById(R.id.spinnerItemIdTv)).getText().toString();
                Toast.makeText(getActivity(), companyId, Toast.LENGTH_LONG).show();
                Log.w(TAG, "companyId:" + companyId);

            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {


            }
        });

and Spinner Item Layout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/spinnerItemIdTv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#888"
        android:textSize="20sp"
        android:visibility="gone"/>

    <TextView
        android:id="@+id/spinnerItemNameTv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#888"
        android:textSize="20sp" />

</LinearLayout>

But couldnt make it on button click. Any help would be appreciated.

Answer 1

I think you are searching for this

View selectedView = null;  //Declare it as a class level variable so that you don't need to make it final  

spinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            selectedView = view;
        }
        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

And Inside some Button's click event, do like this

btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {    
                if(selectedView!=null){                        
                    String companyId = ((TextView) selectedView.findViewById(R.id.spinnerItemIdTv)).getText().toString();
                }
               else{//Something}    

            }
        });

Answer 2

You have adapter associated with your Spinner and I suppose you have some data structure associated with Adapter. You can get data you need onItemSelected (something like below)

public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
    myData = myArrayList.get(i);
//OR
    myData = myAdapter.getItem(i);
}

myData can be Activity field and you can use later onClick callback assosiated with your button.

Answer 3

You may try this

companySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            Spinner spinComp = (Spinner) view.findViewById(R.id.spinner_company);
            int selCompIndex = spinComp .getSelectedItemPosition();
            String compID = companyList.get(selCompIndex).toString();
            Toast.makeText(getActivity(), compID, Toast.LENGTH_LONG).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {


        }
    });

Where, companyList is ArrayList which you are passing to Spinner Adapter. Hope this works.

Modify your xml to single TextView and use tag for ID.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/spinnerItemNameTv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:tag="yourId"
        android:textColor="#888"
        android:textSize="20sp" />

</LinearLayout>

Now use setText to set the spinner row value and use setTag to set the ID of row and then get the ID like this.

companySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {


                String companyId = ((TextView) view.findViewById(R.id.spinnerItemNameTv)).getTag().toString(); //use parent instead.
                Toast.makeText(getActivity(), companyId, Toast.LENGTH_LONG).show();
                Log.w(TAG, "companyId:" + companyId);

            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {


            }
        });
