我要確認至少選中了一個復選框。下面是我正在使用的代碼。public classGejalaKariesGigiActivityextendsAppCompatActivity { Intent intentData; Button buttonSend; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_gejala_karies_gigi); intentData = new Intent(GejalaKariesGigiActivity.this,HasilDiagnosaActivity.class); buttonSend = (Button) findViewById(R.id.buttonselesai1); buttonSend.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { startActivity(intentData); } }); } public void selectItem(View view){ boolean checked = ((CheckBox) view).isChecked(); switch (view.getId()) { case R.id.checkBoxgigiberlubang:if (checked){ intentData.putExtra("gigi_berlubang","Gigi Berlubang"); }else { intentData.removeExtra("gigi_berlubang"); }break; case R.id.checkBoxngilu:if (checked){ intentData.putExtra("ngilu","Ngilu"); }else { intentData.removeExtra("ngilu"); }break; case R.id.checkBoxadabercak:if (checked){ intentData.putExtra("ada_bercak_hitam_pada_gigi","Ada Bercak Hitam Pada Gigi"); }else { intentData.removeExtra("ada_bercak_hitam_pada_gigi"); }break; default:break; } }}

您必須在if else語句中選中每個復選框是否已選中。
if (chkbox1.isChecked()){
//do your operation
}else if (chkbox2.isChecked()){
//do your operation
}else if (chkbox3.isChecked()){
//do your operation
}else{
// show your alert dialog
}
