错误:启动对话框关闭失败: java.lang.IllegalArgumentException

Question

我之前已经问过这个问题了，here，但是没有人能够回答这个问题。问题是，在“创建”的活动中，我创建了一个警报对话框，这个方法在Android5.0上运行得很好，但是在android中，我得到了一个错误：

逻辑猫：

E/HwLauncher: Launcher dialog dismiss failed : java.lang.IllegalArgumentException: no dialog with id 1 was ever shown via Activity#showDialog

下面是我的活动代码

  private static int SPLASH_TIME_OUT = 3000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

        // Alert Box

        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Internet  not connected");
        builder.setMessage("You need to connect WiFi/Mobile-Data run this app.");
        builder.setCancelable(false);

        builder.setPositiveButton(
                "Go to Settings",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {

                        startActivity(new Intent(Settings.ACTION_SETTINGS));
                        finish();
                    }
                });

        builder.setNegativeButton(
                "Cancel",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        finish();
                    }
                });
        final AlertDialog alert = builder.create();
        alert.show();

        ConnectivityManager cm = (ConnectivityManager)
                getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = cm.getActiveNetworkInfo();

        if (networkInfo != null){

            alert.dismiss();
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    // This method will be executed once the timer is over
                    // Start your app main activity
                    Intent i = new Intent(splash.this, LoginActivity.class);
                    startActivity(i);
                    // close this activity
                    finish();
                }
            }, SPLASH_TIME_OUT);

        }
    }

我尝试过stackoverflow like this one的其他答案，但这些答案都没有帮助我。

编辑：

我已经注释掉了代码的AlertDialog部分，但是错误仍然存在。下面是我现在使用的没有警报对话框的代码

public class splash extends AppCompatActivity {

    private static int SPLASH_TIME_OUT = 3000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);


        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                // This method will be executed once the timer is over
                // Start your app main activity
                Intent i = new Intent(splash.this, LoginActivity.class);
                startActivity(i);
                // close this activity
                finish();
            }
        }, SPLASH_TIME_OUT);
        // Alert Box

        /*
        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Internet  not connected");
        builder.setMessage("You need to connect WiFi/Mobile-Data run this app.");
        builder.setCancelable(false);

        builder.setPositiveButton(
                "Go to Settings",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {

                        startActivity(new Intent(Settings.ACTION_SETTINGS));
                        finish();
                    }
                });

        builder.setNegativeButton(
                "Cancel",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        finish();
                    }
                });

        final Dialog alert = builder.create();
        alert.show();

        //WifiManager wifi =(WifiManager)getApplicationContext().getSystemService(Context.WIFI_SERVICE);

        ConnectivityManager cm = (ConnectivityManager)
                getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = cm.getActiveNetworkInfo();


        if (networkInfo != null){

            alert.dismiss();
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    // This method will be executed once the timer is over
                    // Start your app main activity
                    Intent i = new Intent(splash.this, LoginActivity.class);
                    startActivity(i);
                    // close this activity
                    finish();
                }
            }, SPLASH_TIME_OUT);

        }*/
    }

即使AlertDialog注释掉了，Logcat也会显示相同的错误：

Launcher dialog dismiss failed : java.lang.IllegalArgumentException: no dialog with id 1 was ever shown via Activity#showDialog

        builder.setTitle("Internet  not connected");
        builder.setMessage("You need to connect WiFi/Mobile-Data run this app.");

            }
        } else {
            alert.show();
        }
    }
}

我试过这样做，而且效果很好。下面是我的分级文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.manoj.demoapplication"
        minSdkVersion 19
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'

Answer 2

HwLauncher: Launcher dialog dismiss failed : java.lang.IllegalArgumentException: no dialog with id 1 was ever shown via Activity#showDialog

我在HuaWei MT7-L09(mate7)、EMUI3.0、Android为4.4.2中获得了相同的日志。

日志不是你的应用程序，我发现当我打开手机的任务菜单时，这个日志会显示在日志中。
