Will only read and write one line

Will only read and write one line - java

Program runs fine however I can not figure out why it will only read and write one line. It should be able to write multiple lines and read them into the textview. I have it setup so that when the user clicks add it automatically should read into the textview
public class MainActivity extends AppCompatActivity {
EditText Activity, Miles, Date;
TextView Log;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Activity = (EditText)(findViewById(R.id.editText));
Miles = (EditText)(findViewById(R.id.editText2));
Date = (EditText)(findViewById(R.id.editText3));
Log = (TextView)(findViewById(R.id.textView));
}
public void Add(View view)
{
String Myactivity = Activity.getText().toString() + "\t" + Miles.getText().toString() + "\t" + Date.getText().toString();
try {
FileOutputStream fileOutputStream = openFileOutput("myActivities.txt", MODE_PRIVATE);
fileOutputStream.write(Myactivity.getBytes());
fileOutputStream.close();
Toast.makeText(getApplicationContext(), "Activty Added", Toast.LENGTH_LONG);
FileInputStream fileInputStream = openFileInput("myActivities.txt");
InputStreamReader inputStreamReader = new InputStreamReader(fileInputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
StringBuffer stringBuffer = new StringBuffer();
String action;
while((action = bufferedReader.readLine())!= null)
{
stringBuffer.append(action + "\n");
}
Log.setText(stringBuffer.toString());
} catch (FileNotFoundException e)
{
e.printStackTrace();
Toast.makeText(getApplicationContext(), "Fail", Toast.LENGTH_LONG);
} catch (IOException e)
{
e.printStackTrace();
Toast.makeText(getApplicationContext(), "Fail", Toast.LENGTH_LONG);
}

Add this in your textview xml
android:maxLines="100"
In your code:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:id="#+id/textView"
android:layout_below="#+id/button"
android:maxLines="100" <!-- add android:maxLines to specify the number of lines in textview -->
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_alignParentStart="true" />
Updated:
while((action = bufferedReader.readLine())!= null)
{
Log.setText(Log.getText() + action + "\n");
}

Input from EditText only taking in hints instead of text inputted

I have a basic patient details activity that takes patient details and saves them to a text file. At the moment it works fine only that the input it is receiving from the edit textfields are the hints from edit text and not the actual info I am trying to input. My code to me seems perfect and I cannot see where I am going wrong:
public class PatientDetails extends AppCompatActivity {
public EditText IDNum, name, DOB, weight, height;
public String ID, dob, wght, hght, nme;
public Button b;
public TextView t;
private FileUtility myFile = new FileUtility();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_patient_details);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
IDNum = ((EditText) findViewById(R.id.IDnum));
DOB = ((EditText) findViewById(R.id.DOB));
weight = ((EditText) findViewById(R.id.Weight));
height = ((EditText) findViewById(R.id.Height));
name = ((EditText) findViewById(R.id.name));
b = ((Button) findViewById(R.id.submit));
t = ((TextView) findViewById(R.id.result));
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ID = IDNum.getText().toString();
dob = DOB.getText().toString();
wght = weight.getText().toString();
hght = height.getText().toString();
nme = name.getText().toString();
myFile.createFile(getApplicationContext(), "test");
myFile.writeLine(ID);
myFile.writeLine(dob);
myFile.writeLine(wght);
myFile.writeLine(hght);
myFile.writeLine(nme);
t.setText(myFile.readAll());
}
});
}
}

Try search your code one more time. You cannot get hint text from getText() method... unless you have hard pre-filled that hint as a text in EditText element.

Try this maybe:
IDNum = (EditText) findViewById(R.id.IDnum);

Focus changes to listview once i clear the Edittext

I'm using broadcast receiver to show a dialog.So the flow of code is something like:
Step1 Getting the requestCode value
Step2 Based on this requestCode the broadCast receiver goes to if or else if or else part
Step3 If the value that i entered using some scanner into the EditText(i.e Scan) doesn't matches it shows a Toast "Item Not Available".
Step 4 Once "Item Not Available" toast comes the focus changes to the Listview which is my problem.
Step5 Again if i pass value to the Scan EditText the Listview get click automatically.
So my question is "How to remove focus from the Listview" and set it to the EditText(i.e Scan).
For Reference I'm attaching the snap with code snippet and the layout.xml.Please have a look and drop your suggestions why the focus is going to the listview.

Add a textwatcher to edit text and check when text is not blank and it is not equal to expected text then only switch the focus.
/* Set Text Watcher listener */
yourEditText.addTextChangedListener(passwordWatcher);
and check for text once user enter text
private final TextWatcher passwordWatcher = new TextWatcher() {
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
public void afterTextChanged(Editable s) {
if (s.length() != 0 && passwordEditText.getText().equals("Your expected text")) {
// show your toast and change focus
}
}
}

You should make your listview not focusable by using setFocusable(false) when not required and when you get response correctly from barcode scanner then you can again make your listview focusable.

Invocation target exception in my method toString()

I am novice in Java and Android. I need to send some text data from an one activity to the another activity. This is a method which send these text data to the another activity:
public void commandListener(View target)
{
switch (target.getId())
{
case R.id.button1:
Intent intent = new Intent();
intent.setClass(this, SubActivity.class);
intent.putExtra("Send to the second activity", ++counter);
intent.putExtra("Send person info", somePerson.toString());// INVOCATION TARGET EXCEPTION ON THIS STRING!!!
startActivity(intent);
finish();
break;
case R.id.button2:
Intent intent2 = new Intent();
intent2.setClass(this, ThirdActivity.class);
intent2.putExtra("Send to the third activity", ++counter);
startActivity(intent2);
finish();
break;
default:
counter = 0;
finish();
break;
}
}
In this code I get acception on intent.putExtra("Send person info", somePerson.toString()). somePerson.toString() initiates that exception. Where is my mistake?
SomePerson has a type Person
Here is an implementation of a Person:
public class Person implements Serializable
{
/**
*
*/
private static final long serialVersionUID = 1L;
private String firstName = "Vasya";
private String lastName = "Pupkin";
private Integer age = 58;
private Integer phone = 02;
#Override
public String toString()
{
return "Person [firstName=" + firstName + ", lastName=" + lastName
+ ", age=" + age + "]";
}
public void setName(String name)
{
firstName = name;
}
public void setLastName(String lName)
{
lastName = lName;
}
public void setAge(Integer personAge)
{
age = personAge;
}
public void setPhone(Integer personPhone)
{
phone = personPhone;
}
}
This is a part of code from another activity, which accepts text data from another activity:
static int counter = 0;
String personInfo;
TextView counterView;
TextView personInfoView;
private static final String TAG = "myLogs";
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.second_activity);
counter = getIntent().getExtras().getInt("Send to the second activity");
personInfo = getIntent().getExtras().getString("Send person info");
counterView = (TextView)findViewById(R.id.textView4);
counterView.setText(String.valueOf(counter));
personInfoView = (TextView)findViewById(R.id.textView6);
personInfoView.setText(personInfo);
Log.d(TAG, "Counter value:");
Log.d(TAG, String.valueOf(counter));
}
This is XML-code of activity which send data:

write all getter method for each variable in Person class and set each variable and use below line of code to send some text data from an one activity to the another activity
intent.putExtra("Firstname", somePerson.getFirstName());
intent.putExtra("LastName", somePerson.getLastName());
intent.putExtra("Age", somePerson.getAge());

remove toString() method from somePerson.toString() because u are implementing Serializable so there is no need of toString ()
replace
intent.putExtra("Send person info", somePerson.toString());
with
intent.putExtra("Send person info", somePerson);

I would suggest making the object parcelable instead of serializable since it is much quicker. Then you can just do a putExtra on the parcelable object.
See http://developer.android.com/reference/android/os/Parcelable.html for reference on how to create parcelable objects.

xml (activity) stays open in the back ground when it should close

I am making a quiz android app using Eclipse and I made it so that every question has his own activity, now everything works ok if i answer qustions slow but if i do it faster the xml stays open in the background I even added onPause method but it is still open. I do not know how to use threads but someone told me it would make the app faster so the xml would close. I hope there is an easy fix for my problem if not, can anyone explain me how to use threads.
