在我的代码中，当我选择if- elseIf语句中提到的选项时，我想立即关闭警报对话框并开始活动。我不想要确定和取消按钮。我的代码运行良好（if语句内的语句有效，但仍然存在警告对话框）。感谢帮助
final AlertDialog.Builder builder =
new AlertDialog.Builder(arg0.getContext());
builder.setTitle("Favourities Management");
// TODO Auto-generated method stub
int selected = 0;
builder.setSingleChoiceItems(values, selected, new DialogInterface.OnClickListener() {
@
Override
public void onClick(DialogInterface dialog, int which) {
if (values[which] == "Select Benificiary") {
Intent registerUser = new Intent(FinalUtilityBillPayment.this, ListViewBeneficiaryBillPayment.class);
FinalUtilityBillPayment.this.startActivity(registerUser);
startActivityForResult(registerUser, 1);
} else if (values[which] == "Add Benificiary") {
try {
mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE, null);
mydb.execSQL("CREATE TABLE IF NOT EXISTS " + TABLE + " (ID INTEGER PRIMARY KEY, ReferenceNo TEXT, Mobile Text);");
mydb.close();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Error in creating table", Toast.LENGTH_LONG).show();
}
try {
mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE, null);
mydb.execSQL("INSERT INTO " + TABLE + "(ReferenceNo, Mobile) VALUES('" + ref.getText().toString() + "','" + mob.getText().toString() + "')");
mydb.close();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Error in inserting into table", Toast.LENGTH_LONG).show();
}
} else if (values[which] == "Delete Benificiary") {
Intent registerUser = new Intent(FinalUtilityBillPayment.this, ListViewDeleteBeneficiaryBillPayment.class);
//startActivityForResult(registerUser, 1);
FinalUtilityBillPayment.this.startActivity(registerUser);
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
我的建议是；
final AlertDialog.Builder builder = new AlertDialog.Builder(arg0.getContext());
builder.setTitle("Favourities Management");
// TODO Auto-generated method stub
int selected = 0;
builder.setSingleChoiceItems(values,
selected,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if(values[which]=="Select Benificiary"){
selectBenificiary();
//see more about "dialog.dismiss()" in http://developer.android.com/reference/android/app/Dialog.html#dismiss()
dialog.dismiss();
} else if (values[which]=="Add Benificiary"){
addBenificiary();
//see more about "dialog.dismiss()" in http://developer.android.com/reference/android/app/Dialog.html#dismiss()
dialog.dismiss();
} else if (values[which]=="Delete Benificiary"){
deleteBenificiary();
//see more about "dialog.dismiss()" in http://developer.android.com/reference/android/app/Dialog.html#dismiss()
dialog.dismiss();
}
}
});
AlertDialog alert = builder.create();
alert.show();
//Add parameter case necessary
public void selectBenificiary(){
Intent registerUser = new Intent(FinalUtilityBillPayment.this,ListViewBeneficiaryBillPayment.class);
// FinalUtilityBillPayment.this.startActivity(registerUser);
startActivityForResult(registerUser, 1);
}
//Add parameter case necessary
public void addBenificiary(){
try{
mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE,null);
mydb.execSQL("CREATE TABLE IF NOT EXISTS "+ TABLE +" (ID INTEGER PRIMARY KEY, ReferenceNo TEXT, Mobile Text);");
mydb.close();
}catch(Exception e){
Toast.makeText(getApplicationContext(), "Error in creating table", Toast.LENGTH_LONG).show();
}
try{
mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE,null);
mydb.execSQL("INSERT INTO " + TABLE + "(ReferenceNo, Mobile) VALUES('"+ref.getText().toString() +"','"+ mob.getText().toString() +"')");
mydb.close();
}catch(Exception e){
Toast.makeText(getApplicationContext(), "Error in inserting into table", Toast.LENGTH_LONG).show();
}
}
//Add parameter case necessary
public void deleteBenificiary(){
Intent registerUser = new Intent(FinalUtilityBillPayment.this, ListViewDeleteBeneficiaryBillPayment.class);
//startActivityForResult(registerUser, 1);
FinalUtilityBillPayment.this.startActivity(registerUser);
}
