активность не открывается, когда нажимается кнопка [ANDROID]

Question

Я новичок в андроиде, и я хочу назвать деятельность под названием SetNotification, когда нажата кнопка SET NOTIFICATION от основного действия, для чего я написал этот код, но при нажатии кнопки активность не открывается.

MainActivity.java

package com.example.abc.project1; 

import android.content.Intent; 
import android.os.Bundle; 
import android.support.design.widget.FloatingActionButton; 
import android.support.design.widget.Snackbar; 
import android.support.v7.app.AppCompatActivity; 
import android.support.v7.widget.Toolbar; 
import android.view.View; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.widget.Button; 

public class MainActivity extends AppCompatActivity { 

    private static Button set_not; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
     fab.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) 
         .setAction("Action", null).show(); 
      } 
     }); 
    } 

    public void onClickButtonListener() { 
     set_not = (Button)findViewById(R.id.set_not_btn); 
     set_not.setOnClickListener(
       new View.OnClickListener() { 
        @Override 
        public void onClick(View v) { 
         Intent intent = new Intent("com.example.abc.project1.SetNotification"); 
         startActivity(intent); 
        } 
       } 
     ); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
}

Answer 1

Ваше намерение должно выглядеть следующим образом:

Intent intent = new Intent(MainActivity.this, SetNotification.class); 
startActivity(intent); 

Кстати это не требуется:

public void onClickButtonListener() { } 

Просто кладете кнопку и onclicklistener вне этих линий кода и удалите эти строки: onClickButtonListener

Answer 2

Попробуйте это:

Intent openActivity = new Intent(MainActivity.this, SetNotification.class); 
startActivity(openActivity); 

Answer 3

Try, чтобы обеспечить класс не упаковать имя new Intent() как

Intent intent = new Intent(getActivity(), SetNotification.class); startActivity(intent);

Answer 4

Ваш путь открытия деятельности является неправильным. Попробуйте это так.

set_not.setOnClickListener(
      new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        Intent intent = new Intent(MainActivity.this,SetNotification.class); 
        startActivity(intent); 
       } 
      } 
    );
