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

您无法在一个活动中使用两种onClick()方法。使用此

@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);
    }
}
