當(dāng)我單擊“下一步”時(shí)，我想將電話號(hào)碼從 editText 放入自定義警報(bào)對(duì)話框，如下所示：我已將 getStringExtra 放入 textView 自定義對(duì)話框，但我應(yīng)該單擊“是”，然后顯示號(hào)碼成功。但我想要的是當(dāng)我單擊“下一步”時(shí)，顯示數(shù)字。代碼 ：public void sendVerificationCode() { phoneNumber = countryCode.getFullNumberWithPlus(); // The number i want to display to custom alert dialog Intent moveVerification = new Intent(CreateUserActivity.this, VerificationCode.class); moveVerification.putExtra("sendPhoneNumber", phoneNumber); startActivity(moveVerification); finish();}public void dialogVerification() { dialogVerification = new Dialog(CreateUserActivity.this); dialogVerification.requestWindowFeature(Window.FEATURE_NO_TITLE); dialogVerification.setContentView(R.layout.custom_alert_dialog); dialogVerification.setCanceledOnTouchOutside(false); Button buttonYes = dialogVerification.findViewById(R.id.buttonYes); Button buttonEdit = dialogVerification.findViewById(R.id.buttonEdit); TextView displayNumber = dialogVerification.findViewById(R.id.displayNumber); // I want to display the number at here dialogVerification.getWindow().setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); dialogVerification.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); dialogVerification.show();}

如果您的代碼位于同一活動(dòng)中：
將phoneNumber作為參數(shù)傳遞給dialogVerification()或?qū)⑵渎暶鳛槿肿兞恳灾苯釉谌魏魏瘮?shù)中使用它。
要將其作為參數(shù)傳遞：
致電
dialogVerification()來(lái)自sendVerificationCode()：dialogverification(phoneNumber);
并替換這個(gè)->public void dialogVerification() {
和
public void dialogVerification(int phoneNumber) {
只需將電話號(hào)碼放入 textView 中即可
displayNumber.setText(phoneNumber.toString());
將其聲明為全局變量：在
onStart()類聲明的正下方之前將phoneNumber聲明為int phonNumber;
只需將電話號(hào)碼放入 textView 中即可
displayNumber.setText(phoneNumber.toString());
否則如果這
dialogVerification是在另一個(gè)VerificationCode
將其傳遞給其他活動(dòng)：
Intent intent = new Intent(CreateUserActivity.this, VerificationCode.class);
intent.putExtra("Phone_Number", phoneNumber);
startActivity(intent);并通過(guò)以下方式訪問(wèn)該號(hào)碼VerificationCode：
int phoneNumber= getIntent().getIntExtra("Phone_Number");只需將電話號(hào)碼放入 textView 中即可
displayNumber.setText(phoneNumber.toString());
PS：它是一個(gè)字符串，只需將 every 替換int為String, getIntExtraasgetStringExtra并刪除該.toString()。

我在android最新版本中使用View Binding。
我自定義了警報(bào)對(duì)話框并將所需的值傳遞給對(duì)話框。
private ConnectDialogBinding connectDialogBinding;
private String chargerID;
private void connectDialog() {
? ? // Create the object of
? ? // AlertDialog Builder class
? ? AlertDialog.Builder builder = new AlertDialog.Builder(ConnectActivity.this);
? ? connectDialogBinding = ConnectDialogBinding.inflate(getLayoutInflater());
? ? builder.setView(connectDialogBinding.getRoot());
? ? connectDialogBinding.txtID.setText(chargerID);
? ? builder.setCancelable(false);
? ? // Create the Alert dialog
? ? AlertDialog alertDialog = builder.create();
? ? // Show the Alert Dialog box
? ? alertDialog.show();
? ? connectDialogBinding.cancelBtn.setOnClickListener(new View.OnClickListener() {
? ? ? ? @Override
? ? ? ? public void onClick(View v) {
? ? ? ? ? ? alertDialog.cancel();
? ? ? ? }
? ? });
}

您可以創(chuàng)建一個(gè)靜態(tài)類并創(chuàng)建一個(gè)靜態(tài)字段來(lái)保存phoneNumber變量值。然后您可以在任何地方訪問(wèn)您的phoneNumber 變量。不是最佳實(shí)踐，但這種方法總能奏效
