Answer 1

Button bntoartistpage = (Button) findViewById(R.id.bntoartistpage); 
bntoartistpage.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     Intent inent = new Intent(this, Artist.class); 
     // calling an activity using <intent-filter> action name 
     // Intent inent = new Intent("com.example.luke.sinhalasindu"); 
     startActivity(inent); 
    } 
}); 

Button bntonewmp3page = (Button) findViewById(R.id.bntonewmp3page); 
bntonewmp3page.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     Intent inent = new Intent(this, NewMp3.class); 
     // calling an activity using <intent-filter> action name 
     // Intent inent = new Intent("com.example.luke.sinhalasindu"); 
     startActivity(inent); 
    } 
}); 

Answer 2

你不能在一個活動使用兩種onClick()方法。使用這個

@Override 
public void onClick(View view) { 
    if(view.getId() == R.id.bntoartistpage) 
    { 
     Intent inent = new Intent(this, Artist.class); 
     // calling an activity using <intent-filter> action name 
     // Intent inent = new Intent("com.example.luke.sinhalasindu"); 
     startActivity(inent); 
    } 
    else if(view.getId() == R.id.bntonewmp3page) 
    { 
     Intent inent = new Intent(this, NewMp3.class); 
     // calling an activity using <intent-filter> action name 
     // Intent inent = new Intent("com.example.luke.sinhalasindu"); 
     startActivity(inent); 
    } 
}
