カスタム ダイアログを使用していて、ボタンのクリックを取得したいのですが、ボタンをクリックしても何も起こりません。ぜひご覧ください。
public class custom_dialog extends Dialog {
Context m_context;
public custom_dialog (Context context) {
super(context);
// TODO Auto-generated constructor stub
this.m_context = context;
}
public custom_dialog (Context context, int theme) {
super(context,theme);
// TODO Auto-generated constructor stub
this.m_context = context;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public void onClick(View view) {
switch(view.getId()) {
case R.id.blue0:
Toast.makeText(getApplicationContext(),"hii..",Toast.LENGTH_SHORT).show();
break;
}
}
}
これは、logcat で発生するエラーです。

カスタムダイアログを呼び出すボタンイベントです。
public void button1(View view)
{
final custom_dialog dialog = new custom_dialog(this,R.style.Theme_Dialog);
WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();
lp.dimAmount = 0.1f;
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
// set the custom dialog components - text, image and button
awesomeAdapter = new AwesomePagerAdapter();
awesomePager = (ViewPager)dialog. findViewById(R.id.pager);
awesomePager.setAdapter(awesomeAdapter);
dialog.show();
}
