The Implementation of a spinners is causing my app to crash

The Implementation of a spinners is causing my app to crash - android

This is the Java end. It has the Spinner adapters and also the setOnItemClickListener methods. When I comment the "spTitles" setadAdapter method, the program runs. However the program runs whether or not I comment the spCategories setAdapter method

Can anyone help please? When click on the quiz button the application will close. I want it to go to quiz page which called HomeScreen.java

looks good to me, did u declare the second activity in the manifest file? :
<activity android:name="HomeScreen"/>
If that doesn't work, use some break points and the debugger, hope it helps.

how to set text of an EditText view in multiple used fragments?

i am creating an app that has a tabbed interface using TabHost and fragments, and the user needs to select the time using a TimePickerDialog and the selected time is populated into an EditText view, so i moved the time picker to a fragment so i can use it in multiple tabs which works but the problem is when i set the time using the dialog EditText view that is populated is the one in the last tab not the one the TimePickerDialog was opened from, how do i deal with this?
here is the layout for time picker fragment
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="time"
android:ems="10"
android:id="#+id/timePicker"
android:focusable="false"
android:hint="#string/time"
android:onClick="onClickTime"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_alignParentStart="true"
android:layout_alignParentEnd="true"/>
</RelativeLayout>
and here is the code that populates the EditText view which is stored in MainActivity.java
public void onClickTime(View view) {
final Calendar c = Calendar.getInstance();
int cHour = c.get(Calendar.HOUR_OF_DAY);
int cMinute = c.get(Calendar.MINUTE);
TimePickerDialog timePickerDialog = new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
c.set(Calendar.HOUR_OF_DAY, hourOfDay);
c.set(Calendar.MINUTE, minute);
scheduleDate = c.getTime();
SimpleDateFormat dateFormat = new SimpleDateFormat("hh:mm a", Locale.US);
EditText timeInput = (EditText)findViewById(R.id.timePicker);
timeInput.setText(dateFormat.format(scheduleDate));
}
}, cHour, cMinute, false);
timePickerDialog.show();
}

use this
enter link description here
dependencies {
compile 'com.wdullaer:materialdatetimepicker:2.3.0'
}
and
Implement your fragment an OnTimeSetListener
and in fragment to show TimePickerDialog
Calendar now2 = Calendar.getInstance();
TimePickerDialog tpd = TimePickerDialog.newInstance(
NewActivity.this, now2.get(Calendar.HOUR_OF_DAY), now2.get(Calendar.MINUTE),
now2.get(Calendar.SECOND), false
);
tpd.show(getFragmentManager(), "Select Time");
And
#Override
public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute) {
String time = "You picked the following time: "+hourOfDay+"h"+minute;
timeTextView.setText(time);
}

Datepicker and TimePicker dialogs take two clickes of button

So for the life of me I can not find the reason behind needing to click twice on the start date and start time for the picker dialog to open. I have searched these forums many times and they have all been mostly related to edit text fields whereas mine is a simple button but the onClickListener takes two hits. Thanks in advance.

Hmm, your code looks ok. Can you try adding android:focusable="false" to your buttons. I'm curious if the problem is that you're just requesting focus the first click and the second actually initiates the click.
Also, if this doesn't help, can you put some logs in your click listener and also in the public void showTimePickerDialog(View v) { method as well ... to see if it's triggered the first click at all.

Try to add delay on button click it will avoid multi click
date.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
date.setEnabled(false);
showDatePickerDialog(main);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
date.setEnabled(true);
}
}, 100);
}
});

prevent result from shown unless click the button

hi i want to show the result in edittext 2 only after click the convert button
also
the second button (clear) not shown when i run the program how to show it as the screen size is small
here is the code
package converter.com;

s1.setAdapter(adapter);
s1.setOnItemSelectedListener(new OnItemSelectedListener() {

#Override

convert.setOnClickListener(new OnClickListener() {

}
});
clear.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
txt2.setText(" ");
}
});
}
}
here is the xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>

You can do the following to hide txt2 when you first create the activity:
txt2.setVisibility(View.GONE);
Then in the click handler for the convert button:
txt2.setVisibility(View.VISIBLE);
In the click handler for the clear button, presumably you would want to make it GONE again.
Regarding the problem of the clear button being off the screen: wrap your LinearLayout in a ScrollView (making the ScrollView the top view of the hierarchy with a single LinearLayout child). That way the user can scroll down to see all the content of your layout. You need to change the height of the LinearLayout to wrap_content:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#cad1d9"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
. . .
</LinearLayout
</ScrollView>
