I am trying to get EditText value through below code. The activity is used for adding two strings. In the layout, I already put onSave and onCancel method. But when I press button linked to onSave, it shows null pointer exception error.
Activity:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
public class AddTimeActivity extends Activity {
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.time_item);
}
public void onCancel(View view){
this.setResult(RESULT_CANCELED);
finish();
}
public void onSave(View view){
Intent intent = getIntent();
EditText timeView = (EditText)view.findViewById(R.id.time_view);
String time = timeView.getText().toString();
intent.putExtra(TimeTrackerActivity.TIME_KEY, time);
EditText notesView = (EditText)view.findViewById(R.id.notes_view);
String notes = notesView.getText().toString();
intent.putExtra(TimeTrackerActivity.NOTES_KEY, notes);
this.setResult(RESULT_OK, intent);
finish();
}
}
Layout:
...
<EditText
android:id="#+id/timeView"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</EditText>
<EditText
android:id="#+id/notes_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textMultiLine"
android:gravity="top"
android:layout_weight="1"
android:layout_marginBottom="10dp"/>
...
<Button
android:onClick="onSave"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Save" />
<Button
android:onClick="onCancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Cancel" />
...
Error Message from Debugger
E/AndroidRuntime(1123): Caused by: java.lang.NullPointerException
E/AndroidRuntime(1123): at com.timetracker.AddTimeActivity.onSave(AddTimeActivity.java:34)
I tried to check and the value of timeView through debugger and it is null.
Could anybody help?
You are looking for the id time_view (findViewById(R.id.time_view)), but you declare in the XML the ID timeView (android:id="#+id/timeView"). Make them the same and it should fix it.
Also, you should not call it on the view, but on the activity, e.g:
EditText timeView = (EditText)findViewById(R.id.time_view);
Your xml has
android:id="#+id/timeView"
But your code has
EditText timeView = (EditText)view.findViewById(R.id.time_view);
Change above line to.
EditText timeView = (EditText)view.findViewById(R.id.timeView);

Main Class
public class Lipok extends AppCompatActivity implements View.OnClickListener {
Toolbar mActionBarToolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lipok);
mActionBarToolbar=(Toolbar)findViewById(R.id.CHAPTERS);

Intent intent = new Intent(this, YOUR_ACTIVITY_NAME.class);
intent.putExtra("DATA", text);
startActivity(intent);
// Or else you can do whatever you want to do here with that text
}
}
Then in your other activity
String data = getIntent().getStringExtra("DATA");
YOUR_TEXTVIEW_NAME.setText(data);
This is basics of Android so before answering I suggest you to go
through basic tutorials before posting on Stackoberflow.
Now,
Here is how you can access the items from your string_array.
String[] chapters= getResources().getStringArray(R.array.chapters);
Now,here is pseudo code that might help you.
btn1.setOnClickListener(
your_text_view.setText(chapters[0])
)
//Here 0 means your first item, likewise you can access items by their index in
array
I am a noob at this, so going to keep it short.
This is a practice app which sends data from first activity to second activity as a message and then the first activity receives data from the second activity as a message. The tutorial I'm following instructed me to use the StartActivityForResult() function to extract data from a second activity to the first activity. I have two questions:
What is wrong with this code:
I. The MainActivity.java file
package com.example.android.twoactivitiesredo;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private static final String LOG_TAG = MainActivity.class.getSimpleName();
//LOG_TAG contains the name of the class package, encapsulated for ease
public static final String EXTRA_MESSAGE =
"com.example.android.twoactivities.extra.MESSAGE";
//This will be used as the unique key to send data to the second Activity
public static final int TEXT_REQUEST = 1;
//This is used to define the key for a particular type of response that
you're interested in.
private EditText mMessageEditText;
//This EditText is used to send the message to the second activity
private TextView mReplyHeadTextView;
private TextView mReplyTextView;
//These private variables hold the reply header and the reply TextViews
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMessageEditText = (EditText) findViewById(R.id.editText_main);
mReplyHeadTextView = (TextView) findViewById(R.id.textHeaderReply);
mReplyTextView = (TextView) findViewById(R.id.textMessageReply);
}
public void launchSecondActivity(View view) {
Log.d(LOG_TAG, "Button Clicked!");
Intent intent = new Intent(this, SecondActivity.class);
String message = mMessageEditText.getText().toString();
//Gets the data from EditText, converts it to String, and stores it in message
intent.putExtra(EXTRA_MESSAGE,message);
startActivityForResult(intent, TEXT_REQUEST);
}
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode,resultCode,data);
if(requestCode == TEXT_REQUEST){
if(resultCode == RESULT_OK){
String reply = data.getStringExtra(SecondActivity.EXTRA_REPLY);
mReplyHeadTextView.setVisibility(View.VISIBLE);
mReplyTextView.setText(reply);
mReplyTextView.setVisibility(View.VISIBLE);
}
}
}
}
II. The SecondActivity.java file
package com.example.android.twoactivitiesredo;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
public class SecondActivity extends AppCompatActivity{
public static final String EXTRA_REPLY =
"com.example.android.twoactivities.extra.REPLY";
//This tag will be used as a key to send reply to first activity
private EditText mReply;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
Intent intent = getIntent();
//Gets the intent that activated this activity
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
//This extracts the extra text sent along with this key String, thus
receiving the text
TextView textView = (TextView) findViewById(R.id.text_message);
textView.setText(message);
mReply = (EditText) findViewById(R.id.replyEditText);
//Do not reuse the intent from the first activity, create a new one
Intent replyIntent = new Intent();
setResult(RESULT_OK,replyIntent);
//RESULT_OK has the value -1 and is used as a Result code in the Activity
class
//to check that the data is send without a complication
finish();
}
public void returnReply(View view) {
}
}
III. The activity_main.xml file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textMessageReply"
android:layout_below="#+id/textHeaderReply"

</RelativeLayout>
V. The AndroidManifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</activity>
</application>
</manifest>
I am sorry if the code is taking a lot of space, but I really needed help in clarifying my doubts and problems here, about why this code isn't working.
Thanks in advance to all the answers.
Replace your secondActivity.java with this:
package com.example.android.twoactivitiesredo;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
public class SecondActivity extends AppCompatActivity{
public static final String EXTRA_REPLY =
"com.example.android.twoactivities.extra.REPLY";
//This tag will be used as a key to send reply to first activity
private EditText mReply;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
TextView textView = (TextView) findViewById(R.id.text_message);
textView.setText(message);
mReply = (EditText) findViewById(R.id.replyEditText);
}
public void returnReply(View view) {
Intent replyIntent = new Intent();
String replyMessage = mReply.getText().toString();
replyIntent.putExtra(EXTRA_REPLY, replyMessage);
setResult(RESULT_OK,replyIntent);
finish();
}
}
In activity_second.xml

I created the simple application App, the user enters his name in EditText and click on "Enter here" button and store his name in String variable that is instance variable then will move to another activity "activity_welcome" and will display his name in TextView
My problem:
when I create an object from Main Class to get the variable name in welcome Class when running this app, the name do not store in TextView that means that
the object main refers to null
My question:
why object main refer to null?
When I make the variable name as a static variable the app will display the name in TextView that mean that object main store the value of name variable
Note:
Main class

String name ;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText=findViewById(R.id.et) ;
}
public void Go (View v){
name=editText.getText().toString() ;

startActivity(intent);
}

Just keep it simple and put string inside your intent when you go to another activity, obtain intent, and then string from the intent.
public void Go (View v){
name=editText.getText().toString() ;
Intent intent= new Intent(this,Welcome.class);
intent.putExtra("name", name);
startActivity(intent);
}
Obtain it in your welcome activity like this.
#Override
protected void onCreate( Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_welcome);
textView =findViewById(R.id.tv);
Intent intent = getIntent();
if(intent!=null) {
String name = intent.getStringExtra("name");
Toast.makeText(this, name, Toast.LENGTH_SHORT).show();
textView.setText(name);
}
}
I'm trying to have a text field and a text view, and set the text view text to whatever is on the the field.
This is my code:
MainActivity.java
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView helloMessage = (TextView) findViewById(R.id.hello); //define textView to show the message
EditText nameField = (EditText) findViewById(R.id.Name); // Text field to get the name from
String getName = nameField.getText().toString(); // set a variable with the text field's value
helloMessage.setText(getName); // set text on the hello textview to be the name.
}
}
activity_main.xml:
<LinearLayout 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"

android:layout_width="match_parent"
android:layout_height="wrap_content"

android:ems="10"
android:id="#+id/Name" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/hello"/>
</LinearLayout>
Thanks in advance for any sort of help!
Brother you need to setContentView(R.layout.activity_main); before finding any other view
You forgot to add setContentView(R.layout.activity_main) to onCreate()
I want to show TextView editable like the app "Google Keep" but
EditText text = (EditText)findViewById(R.id.edittext);
String value = text.getText().toString();
didn't work
Hello I've made a example that I think you can use:
Layout:
<LinearLayout 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"
android:orientation="vertical"
>
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:textColor="#FF0000"
android:text="#string/hello_world" />
<EditText
android:id="#+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/getInfoButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="GET INFO"
android:layout_gravity="center_horizontal"
/>
</LinearLayout>
MainActivity
package com.example.testedittext;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView info;
private EditText input;
private Button getInfo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
info = (TextView) findViewById(R.id.textView);
input = (EditText)findViewById(R.id.editText);
getInfo = (Button)findViewById(R.id.getInfoButton);
getInfo.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String inputText = input.getText().toString();
info.setText(inputText);
}
});
}
}
Here is the output:
Hope this helps,
Cheers
That is the correct syntax for getting the text in string format of an edittext.
The value of String "value" is actually "" right now because you called
text.getText().toString();
IMMEDIATELY after EditText text was instantiated. As you can imagine, the moment it was created, there was no text inside it, so that's why "value" has an empty string.
If you want to retrieve the value of the edittext at a specific call, I'd recommend adding a button in your xml layout, and in your code, add this:
Button button = (Button) findViewById(R.id.somebutton);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
text.getText().toString();
}
});
This will get the current String value of the edittext when you click on the button.
You have to use the value String somewhere else it will tell you that its not used.
Then you have to use that piece of code at a point of time where you have had a change to set the value of that ediettext.
