Get Value of a Edit Text field

By using getText():

Button   mButton;
EditText mEdit;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mButton = (Button)findViewById(R.id.button);
    mEdit   = (EditText)findViewById(R.id.edittext);

    mButton.setOnClickListener(
        new View.OnClickListener()
        {
            public void onClick(View view)
            {
                Log.v("EditText", mEdit.getText().toString());
            }
        });
}

---

I guess you will have to use this code when calling the "mEdit" your EditText object :

myActivity.this.mEdit.getText().toString()

Just make sure that the compiler know which EditText to call and use.

Get value from an EditText control in android. EditText getText property use to get value an EditText:

EditText txtname = findViewById(R.id.name);
String name      =  txtname.getText().toString();

---

I hope this one should work:

Integer.valueOf(mEdit.getText().toString());

I tried Integer.getInteger() method instead of valueOf() - it didn't work.

---

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

  Button  rtn = (Button)findViewById(R.id.button);
  EditText edit_text   = (EditText)findViewById(R.id.edittext1);

    rtn .setOnClickListener(
        new View.OnClickListener()
        {
            public void onClick(View view)
            {
                Log.v("EditText value=", edit_text.getText().toString());
            }
        });
}

You might also want to take a look at Butter Knife. It aims at reducing the amount of boilerplate code by using annotation. Here is a simple example:

public class ExampleActivity extends ActionBarActivity {

    @InjectView(R.id.name)
    EditText nameEditText;

    @InjectView(R.id.email)
    EditText emailEditText;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_example);
        Butterknife.inject(this);
    }

    @OnClick(R.id.submit)
    public void onSubmit() {
         Editable name = nameEditText.getText();
         Editable email = emailEditText.getText();
    }
}

Just add the following dependency to your build.gradle:

compile 'com.jakewharton:butterknife:x.y.z'

As an alternative there is also AndroidAnnotations.

Shortest & Simplest

getText(editText);

getText(button);

getText(textView);

Little Workaround

Just make method in your BaseActivity / create BaseActivity if you don't have.

public class BaseActivity extends AppCompatActivity{
    public String getText(TextView tv) {
        return tv.getText().toString().trim();
    } 
}

And extend your all activities by this BaseActivity.

public class YourActivity extends BaseActivity {
  @Override
  public void onCreate(Bundle savedInstanceState){
     getText(editText);
     getText(button);
     getText(textView);
  }
}

Note that EditText, Button extends TextView, so I created only getText(TextView tv).

---

String value = YourEditText.getText().toString;

---

A more advanced way would be to use butterknife bindview. This eliminates redundant code.

In your gradle under dependencies; add this 2 lines.

compile('com.jakewharton:butterknife:8.5.1') {
        exclude module: 'support-compat'
    }
apt 'com.jakewharton:butterknife-compiler:8.5.1'

Then sync up. Example binding edittext in MainActivity

import butterknife.BindView;   
import butterknife.ButterKnife; 

public class MainActivity {

@BindView(R.id.name) EditTextView mName; 
...

   public void onCreate(Bundle savedInstanceState){
         ButterKnife.bind(this); 
         ...
   }

}

But this is an alternative once you feel more comfortable or starting to work with lots of data.

step 1 : create layout with name activity_main.xml

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rl"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    tools:context=".MainActivity"
    android:background="#c6cabd"
    >
    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="17dp"
        android:textColor="#ff0e13"
        />
    <EditText
        android:id="@+id/et"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/tv"
        android:hint="Input your country"
        />
    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Get EditText Text"
        android:layout_below="@id/et"
        />
</RelativeLayout>

Step 2 : Create class Main.class

public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn = (Button) findViewById(R.id.btn);
        final TextView tv = (TextView) findViewById(R.id.tv);
        final EditText et = (EditText) findViewById(R.id.et);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String country = et.getText().toString();
                tv.setText("Your inputted country is : " + country);
            }
        });
 }
}

If you are using Kotlin and wants to make it generic you can use the Extension function

Extension function:

fun EditText.getTextString(): String {
    this.text.toString()
}

and call this method directly from your EditText

yourEditText.getTextString()

---

Try this code

final EditText editText = findViewById(R.id.name); // your edittext id in xml
Button submit = findViewById(R.id.submit_button); // your button id in xml
submit.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) 
    {
        String string = editText.getText().toString();
        Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
    }
});
