Why my android application has stopped?

My project won't open on my device, it say's "Unfortunately,myApp has stopped".
this is my manifest:
this is my activity java :
package bismillah.project;
import android.app.Activity;
import android.os.Bundle;

import android.content.Intent;
import android.widget.Button;

public class Project2Activity extends Activity {
public static int a,b,c;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//coding start here!!
//input data
EditText pek=(EditText)findViewById(R.id.editText1);
String value=pek.getText().toString();
final int pekerja=Integer.parseInt(value);
EditText lam=(EditText)findViewById(R.id.editText2);

//button proses

button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

}
}
}
}
});
//button reset
Button button2=(Button)findViewById(R.id.Button2);
button2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

});
//button pindah activity
Button button3=(Button)findViewById(R.id.Button3);
button3.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent i =new Intent(getApplicationContext(),activity2.class);
startActivity(i);
}
});
}
}

I tried your code and I had to delete some stuff from your XML file because it was creating some bugs. It might be related to me but here's your XML I was able to use:
But please do not change your XML file before trying the solution below. If it still doesn't work, you should consider the elements I removed.

Next I created your Project2Activity java class and activity2 (pretty much empty since you gave no info about it).
So when trying to run your application you get the following error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.application.so/com.example.application.so.Project2Activity}: java.lang.NumberFormatException: For input string: ""
and it is at :
at com.example.application.so.Project2Activity.onCreate(Project2Activity.java:24)
now if we consider this lines 23 and 24:
String value=pek.getText().toString(); // line 23
final int pekerja=Integer.parseInt(value); // line 24
The error is that you are trying to read (line 23) your editText Value at the creation of the activity, at that time, your editText is still blank which means value will be equal to "" (empty string).
What you want to do instead is to put your lines from 22 to 33 (the ones below) in a button click event, I tried putting them in your button 1 click event and your app doesn't crash any more:
EditText pek=(EditText)findViewById(R.id.editText1);
String value=pek.getText().toString();
final int pekerja=Integer.parseInt(value);
EditText lam=(EditText)findViewById(R.id.editText2);
String value1=lam.getText().toString();
final int lama=Integer.parseInt(value1);
EditText up=(EditText)findViewById(R.id.editText3);
String value2=up.getText().toString();
final int upah=Integer.parseInt(value2);
EditText jum=(EditText)findViewById(R.id.editText4);
String value3=jum.getText().toString();
final int jumlah=Integer.parseInt(value3);
So to summarize, the problem is that you are extracting empty strings from your editTexts and trying to make integers out of them. Instead try making that all reading and integer extracting process on the click of a button where your really need these inputs. just like get the inputs and the final moment.
You should pay attention to your logcat (error messages), it is quite helpful.
What you can also do is to verify that your editTexts are not empty while trying to extract strings from them and raise exception or Toast if they are empty. Nothing too complicated just something like:
if (value.equals("")):
// editText is empty so do something
You can refer to this link for further understanding of how to know when an editText is empty.

getText() returns empty string (android studio)

I have a little question here about android development.
I already searched on internet, but i still can't find the solution.
I want to getText() from a view, but it just returns an empty ("") string.
Here's my .java code:
public void kotakCentang(View view)
{
RelativeLayout vwParentRow = (RelativeLayout)view.getParent();
TextView id_test = (TextView)vwParentRow.getChildAt(0);
TextView nama_test = (TextView)vwParentRow.getChildAt(1);
tugas_status = (TextView)vwParentRow.getChildAt(5);
tanggalKasih = (EditText)vwParentRow.getChildAt(6);
tanggalKumpul = (EditText)vwParentRow.getChildAt(8);
waktuKasih = (EditText)vwParentRow.getChildAt(7);
waktuKumpul = (EditText)vwParentRow.getChildAt(9);
tugasKompleksitas = (EditText)vwParentRow.getChildAt(10);
Tugas tugas = new Tugas();
TugasRepo tugass = new TugasRepo(this);
tugas.nama = nama_test.getText().toString();
tugas.waktuDikasih = waktuKasih.getText().toString();
tugas.waktuDikumpul = waktuKumpul.getText().toString();
tugas.tanggalDikasih = tanggalKasih.getText().toString();
tugas.tanggalDikumpul = tanggalKumpul.getText().toString();
tugas.kompleksitas=Integer.parseInt(tugasKompleksitas.getText().toString());
tugasKompleksitas.getText().toString();
}
The getText() which returns empty string is just the tugas.waktuDikasih, and tugas.waktuDikumpul .
Thank you for your help.

The keyboard is coming upon the EditText field & thus hiding it. How to prevent the keyboard from hiding the EditText field?

My EditText is at the bottom of screen, so when I'm tapping on it to edit it, the keyboard is hiding it. I want that when I tap on EditText, the keyboard should remain below it & should not hide it.
Here's the link to the screenshot showing EditText before tapping on it: http://imgur.com/cgme1HT
Here's the link to the screenshot after tapping on EditText (the EditText field is below the keyboard now): http://imgur.com/nloFrkn

userProfilePicture = (ImageView) findViewById(R.id.userProfilePicture);
userProfilePicture.setOnClickListener(new View.OnClickListener() {

I really have no clue about what to do here!
Please let me know.
I'm new to StackOverflow, so please cooperate.
Thanks in advance.

I had the same issue where the softkeyboard was on top of the EditText views which were placed on the bottom of the screen. I was able to find a solution by adding a single line to my AndroidManifest.xml file's relevant activity.
Put layout inside a ScrollView.
android:windowSoftInputMode="adjustResize|stateHidden"
This is how the whole activity tag looks like:
<activity
android:name="com.my.MainActivity"
android:screenOrientation="portrait"
android:label="#string/title_activity_main"
android:windowSoftInputMode="adjustResize|stateHidden" >
</activity>
Here the most important value is the adjustResize. This will shift the whole UI up to give room for the softkeyboard.

Simply use a ScrollView as the parent view in your xml file.

Options-1
Try using android:windowSoftInputMode="adjustPan" in activity in AndroidManifest.xml
Options-2
Use ScrollView as parent in xml. Replace your xml with this:
<ScrollView 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"
tools:context="com.abc.xyz.SettingUpUserProfile" >

Thank you all for your answers.
I solved the problem by changing my activity_setting_up_user_profile.xml file's code to this:

Crash's trying to find view

I have a slight problem that I have been stuck on. I have narrowed it down and it seems that my application is crashing on create when i am trying to find a text view. I do not understand why, maybe i have been looking at this to long and dont see the obvious.
Any help would be appreciated.
Thanks.

There are two possible things possible. Either you want all Textviews or all EditText.
If you want all Textview then replace all your EditTextin java file with Textview.
Textview fullName;
fullName = (Textview )findViewById(R.id.personsNameTv);
If you want all EditText then replace all Textview in xml with EditText.
<EditText
android:id="#+id/personsNameTv"
.../>

In XML you are using Text-view and in java file you define it Edit-text
<TextView
android:id="#+id/personsNameTv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/fullName"
android:textColor="#FFFFFF"
android:textSize="15sp" />
Replace with
<EditText
android:id="#+id/personsNameTv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/fullName"
android:textColor="#FFFFFF"
android:textSize="15sp" />

Error when generating dynamic content

I'm trying to generate form elements from a template when the user clicks on a button. I created the template and the container layout for the new forms with XML. Its successfully generating the first form where I'm telling it to generate, but when I try to generate more forms beyond the first one its giving me an error: "the specified child already has a parent. You must call removeView() on the child's first parent". Any clue as to what I should do so as to generate more than one element? I've tried changing the id of the newly created forms but that's giving me a null pointer exception and crashing. Thank you.
public class MakeQuestion extends Activity implements OnClickListener{
private static final int MY_BUTTON = 9000;
int templateID = 1;
Button b;
Button target;
View insertPoint;
Button testTemplate;
View v1;
RelativeLayout.LayoutParams templateParams;
LayoutInflater vi;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.make_question);
Initialize();
}
public void Initialize(){
//button for adding new forms
b = (Button) findViewById(R.id.makeLayoutButton);
b.setOnClickListener(this);
//get the template form to be duplicated
vi = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v1 = vi.inflate(R.layout.form_template, null);
//set the params for the element that will have dynamically generated content below it
templateParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
//container where forms will be contained in
insertPoint = findViewById(R.id.questionsContainer);
//view where new form will go below
View belowContainer = findViewById(R.id.questionTemplateFake);
//set id for layout params of view
belowContainer.setId(1);
//set rule for new forms to go below view 'belowContainer'
templateParams.addRule(RelativeLayout.BELOW, belowContainer.getId());
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.makeLayoutButton:
v1 = vi.inflate(R.layout.form_template, null);
//add view to the insertPoint
((LinearLayout) insertPoint).addView(v1);
break;
}
}
}
Added forms should go in "questionsContainer" which is set to be below "questionTemplateFake"

You are trying to add the same instance over and over again. Thus the message that "specific child already exists". You would have to create a new template layout instance with different ID (I suppose) and then try to add it in.
So rather than:
((RelativeLayout) insertPoint).addView(v1, templateParams);
and adding v1 again. Create a new instance
v1 = vi.inflate(R.layout.form_template, null);
set the id for good measures and then add it again in view.
I suppose you don't need to set the id, but you can read more about how id's work here
