我在Alert对话框中有一个单选按钮,然后iam验证单选按钮,如果没有选中的单选按钮,它将显示Toast消息,并且必须保持显示警告对话框。但是在我的代码下面,当显示吐司时,警报对话框将关闭。
private void showPopupSubscribe() {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
final View dialogView = getLayoutInflater().inflate(R.layout.paket_subscribe, null);
builder.setView(dialogView);
builder.setCancelable(false);
builder.setIcon(R.drawable.logo_1);
builder.setTitle(R.string.subscription_package);
final RadioGroup radioGroup = dialogView.findViewById(R.id.rgSubscribe);
builder.setPositiveButton("Next", new DialogInterface.OnClickListener() {
@SuppressLint("ResourceType")
@Override
public void onClick(DialogInterface dialog, int which) {
int selected = radioGroup.getCheckedRadioButtonId();
if (selected == R.id.rbA) {
smsCode = vv0;
} else if (selected == R.id.rbB) {
smsCode = vv1;
} else if (selected == R.id.rbC) {
smsCode = vv2;
} else if (selected == R.id.rbD) {
smsCode = vv3;
}
if (selected == -1 ){
Toast.makeText(CatalogHomeActivity.this, "Pilih paket untuk berlangganan", Toast.LENGTH_SHORT).show();
}else {
pdSubs.show();
doCharging();
dialog.dismiss();
}
}
});
dialog = builder.create();
dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
@Override
public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
dialog.dismiss();
finish();
}
return true;
}
});
dialog.show();
}

首先删除setPositiveButton(); 然后设置正面按钮 如果你想在setOnShowListener
中那个关闭对话框之后 ...
builder.setPositiveButton(android.R.string.ok, null);
...
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
Button button = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_POSITIVE);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (selected == -1 ){
Toast.makeText(CatalogHomeActivity.this, "Pilih paket untuk berlangganan", Toast.LENGTH_SHORT).show();
}else {
pdSubs.show();
doCharging();
dialog.dismiss();
}
}
});
}
});
dialog.show();

尝试以下代码。
private void showPopupSubscribe() {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
final View dialogView = getLayoutInflater().inflate(R.layout.paket_subscribe, null);
builder.setView(dialogView);
builder.setCancelable(false);
builder.setIcon(R.drawable.logo_1);
builder.setTitle(R.string.subscription_package);
builder.setPositiveButton("Next", null);
final RadioGroup radioGroup = dialogView.findViewById(R.id.rgSubscribe);
dialog = builder.create();
dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
@Override
public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
dialog.dismiss();
finish();
}
return true;
}
});
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
Button button = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_POSITIVE);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int selected = radioGroup.getCheckedRadioButtonId();
if (selected == R.id.rbA) {
smsCode = vv0;
} else if (selected == R.id.rbB) {
smsCode = vv1;
} else if (selected == R.id.rbC) {
smsCode = vv2;
} else if (selected == R.id.rbD) {
smsCode = vv3;
}
if (selected == -1 ){
Toast.makeText(CatalogHomeActivity.this, "Pilih paket untuk berlangganan", Toast.LENGTH_SHORT).show();
}else {
pdSubs.show();
doCharging();
dialog.dismiss();
}
}
});
}
});
dialog.show();
}
