pertama kau masukan dibawah arahan untuk 

activity layoutnya :

<RelativeLayout     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="#5fb0c9">      <TextView         android:id="@+id/login_title"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_marginBottom="16dp"         android:layout_marginTop="22dp"         android:gravity="center"         android:text="@string/account_login"         android:textColor="#fff"         android:textSize="26sp"         android:textStyle="bold" />      <LinearLayout         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_below="@+id/login_title"         android:layout_marginLeft="30dp"         android:layout_marginRight="30dp"         android:layout_marginTop="70dp"         android:background="#fff"         android:padding="20dp"         android:orientation="vertical">          <LinearLayout             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:orientation="vertical"             android:paddingTop="30dp">              <EditText                 android:id="@+id/username"                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:singleLine="true"                 android:hint="@string/user_name"                 android:inputTyzpe="textEmailAddress" />              <EditText                 android:id="@+id/password"                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:layout_marginTop="16dp"                 android:singleLine="true"                 android:hint="@string/password"                 android:inputType="textPassword"/>              <TextView                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:layout_gravity="right"                 android:paddingTop="5dp"                 android:text="@string/forgot_password"                 tools:ignore="RtlHardcoded" />               <Button                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:layout_margin="22dp"                 android:background="#d67601"                 android:text="@string/sign_in"                 android:textAllCaps="false"                 android:textColor="#fff"                 android:textSize="18sp"                 android:onClick="ButtonLogin"/>         </LinearLayout>     </LinearLayout>      <ImageView         android:id="@+id/imageView"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_below="@+id/login_title"         android:paddingTop="35dp"         android:layout_centerHorizontal="true"         app:srcCompat="@mipmap/ic_launcher_round"         tools:ignore="ContentDescription" />  </RelativeLayout>

untuk class activity_login :

import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.EditText; import android.widget.Toast;  public class LoginActivity extends AppCompatActivity{      public static selesai String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";     public static selesai String EXTRA_MESSAGE2 = "com.example.myfirstapp.MESSAGE2";      @Override    protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_login);     }      public void ButtonLogin(View view){         Toast.makeText(this, "Login Bro!", Toast.LENGTH_SHORT).show();         EditText editText = (EditText) findViewById(R.id.username);         String message = editText.getText().toString();         EditText editText2 = (EditText) findViewById(R.id.password);         String message2 = editText2.getText().toString();          if(message.equals("saya")&&message2.equals("test")){              Intent intent = new Intent(this, MainActivity.class);             intent.putExtra(EXTRA_MESSAGE, message);             intent.putExtra(EXTRA_MESSAGE2, message2);             startActivity(intent);         }       } }

activity Main :

import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.widget.TextView;  public class MainActivity extends AppCompatActivity {      @Override    protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);          // Get the Intent that started this activity and extract the string        Intent intent = getIntent();         String message = intent.getStringExtra(LoginActivity.EXTRA_MESSAGE);          // Capture the layout's TextView and set the string as its text        TextView textView = findViewById(R.id.title_main);         textView.setText("WELCOME "+message);     } }
