我在 android activity 中的对话崩溃了，我错过了什么？

Question

这是我的 OnClickListener，我在其中重载了名为

的方法

DialogueSuccessful();

应该启动 Dialouge。

if (Inserted == true) {
    DialogueSuccessful();
    txt_FromDate.setText("");
    txt_ToDate.setText("");
    txt_total_payment.setText("");
} else {
    Toast.makeText(getApplicationContext(), "Did not Insert Data", Toast.LENGTH_LONG).show();
}

这是我的方法实现，应用程序在方法实现期间崩溃

public void DialogueSuccessful() {
    AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
    builder.setMessage("Successfull")
        .setTitle("Hotels Reservation")
        .setPositiveButton("Nice", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // FIRE ZE MISSILES!
            }
        });
    // Create the AlertDialog object and return it
    AlertDialog Dialogue = builder.create();
    Dialogue.show();
}

这是我在 logcat 的异常：

这就是我用来启动我想要的对话的所有代码，我应该添加任何东西吗？

请帮我一个忙，我们将不胜感激谢谢

Answer 1

添加

android:theme="@style/Theme.AppCompat.Light"

在您的 AndroidManifest.xml 文件 activity 标签中。

Answer 2

我认为您在 xml-layout 文件中使用了 onClick 属性。此外，您还没有为您的项目使用合适的主题。显示您的 xml 或应用主题 activity。

Answer 3

修改你对话成功的方法

替换此行

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());

和

AlertDialog.Builder builder =new AlertDialog.Builder(
  new ContextThemeWrapper(getApplicationContext(), android.R.style.Theme_Dialog));

Answer 4

从

切换

getApplicationContext()

至Activity上下文成功

public void DialogueSuccessful(){
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Successfull")
            .setTitle("Hotels Reservation")
            .setPositiveButton("Nice", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    // FIRE ZE MISSILES!
                }
            });
    // Create the AlertDialog object and return it
    AlertDialog Dialogue=builder.create();
    Dialogue.show();
}

我在 android activity 中的对话崩溃了，我错过了什么？

android

android-dialog
