Question

I am having an issue registering a call when a button is clicked.

I have 2 EditTexts, one Button and one CheckBox. I would like to get the onClick() function called when the Button is pressed. Unfortunately, it only happens when the CheckBox is pressed, but it’s not the correct ID so I am confused.

Here is the java code:

Button connect = (Button) findViewById(R.id.connectToServer);
connect.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    ....
}

As you can see, I look for the id “connectToServer”.

This is my .xml file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:background="#ffb6b6b6"
        android:textColor="#ffffffff" android:padding="2px" android:text="Settings" />
    <LinearLayout android:orientation="vertical"
        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:padding="13px">
        <TextView android:layout_width="fill_parent"
            android:layout_height="wrap_content" android:textSize="25px"
            android:textColor="#ffffffff" android:text="Set server settings" />

        <TableLayout android:layout_marginTop="10px"
            android:stretchColumns="1" android:layout_width="fill_parent"
            android:layout_height="wrap_content">
            <TableRow>
                <TextView android:text="IP address:" />

                <EditText android:id="@+id/serverIP" android:maxLength="15" />
            </TableRow>

            <TableRow>
                <TextView android:layout_marginTop="4px" android:text="Port:" />
                <EditText android:id="@+id/serverPort" android:maxLength="15" />
            </TableRow>

        </TableLayout>

        <LinearLayout android:layout_width="fill_parent"
            android:layout_marginTop="10px" android:orientation="horizontal"
            android:layout_height="fill_parent" android:gravity="center">
            <Button android:text="Connect" android:id="@+id/connectToServer"
                android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
        </LinearLayout>
    </LinearLayout>

    <TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:background="#ffb6b6b6"
        android:textColor="#ffffffff" android:padding="2px"
        android:layout_marginTop="10px" android:text="Availability" />
    <LinearLayout android:orientation="vertical"
        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:padding="13px">
        <TextView android:layout_width="fill_parent"
            android:layout_height="wrap_content" android:textSize="25px"
            android:textColor="#ffffffff" android:text="Set device available" />

        <TableLayout android:layout_width="fill_parent"
            android:layout_height="wrap_content" android:layout_weight="1">
            <TableRow>
                <TextView android:layout_marginTop="10px"
                    android:layout_width="wrap_content" android:layout_height="fill_parent"
                    android:layout_weight="1"
                    android:text="Uncheck to disallow anyone from\nremotely connecting to the device." />
                <CheckBox android:id="@+id/checkbox" android:gravity="right"
                    android:checked="true" android:layout_weight="1"
                    android:layout_width="wrap_content" android:layout_height="fill_parent" />
            </TableRow>
        </TableLayout>
    </LinearLayout>
</LinearLayout>

The important line I believe would be this:

<Button android:text="Connect" android:id="@+id/connectToServer"
    android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>

but the code only gets called when the CheckBox button is checked or unchecked. I am not sure why that is.

Thank you very much!

Try this,

Button connect = (Button) findViewById(R.id.connectToServer);


connect.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {

    }

});
