My Code here is calling my class Round List，but when I click「Round 1」Button，nothing happened，I do not get any errors，it just does not，if just does not work，if someone have any idea why這是發生了，請你讓我知道，謝謝。Android Intent not calling class
public class MainActivity extends Activity implements OnClickListener {
public LinearLayout layout;
public LinearLayout roundList;
private Button round1, round2, round3;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ScrollView scroll = new ScrollView(this);
setContentView(scroll);
layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
scroll.addView(layout);
TextView title = new TextView(this);
title.setText("Select Round");
title.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 40);
title.setPadding(6,6,6,6);
title.setTextColor(Color.rgb(255, 150, 0));
title.setGravity(Gravity.CENTER);
layout.addView(title);
roundList = new LinearLayout(this);
roundList.setOrientation(LinearLayout.VERTICAL);
layout.addView(roundList);
Button round1 = new Button(this);
round1.setText("Round 1");
round1.setPadding(15, 15, 15, 15);
round1.setOnClickListener(this);
layout.addView(round1);
Button round2 = new Button(this);
round2.setText("Round 2");
round2.setPadding(15, 15, 15, 15);
round2.setOnClickListener(this);
layout.addView(round2);
Button round3 = new Button(this);
round3.setText("Round 3");
round3.setPadding(15, 15, 15, 15);
round3.setOnClickListener(this);
layout.addView(round3);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

if(v == round1) {

startActivity(round);
}
}//end onClick

現在按鈕點擊的作品，但它只是錯誤 – thechrishaddad
我明白了。爲什麼RoundClass擴展MainActivity而不是Activity？ – Blackbelt
我不好，我改變了。 – thechrishaddad
