Question

我正在尝试更改应用的主题，因此当用户按下按钮时，我会调用以下方法：

activity.setTheme(R.style.BlueTheme);
activity.recreate();

然而，每当发生这种情况时，应用程序进入无限循环，控制台输出为：

02-01 11:36:15.077 9245-9276/org.example.androidscouting E/Surface: getSlotFromBufferLocked: unknown buffer: 0xab7d5680
02-01 11:36:15.131 9245-9276/org.example.androidscouting W/EGL_emulation: eglSurfaceAttrib not implemented
02-01 11:36:15.131 9245-9276/org.example.androidscouting W/OpenGLRenderer: Failed to set EGL_SWAP_BEHAVIOR on surface 0xa3170780, error=EGL_SUCCESS

以上只是永远循环，直到我手动关闭应用程序。

有人能告诉我问题是什么以及如何解决，或者至少指出我正确的方向？

编辑：附加代码

创建：

   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Utils.onActivityCreateSetTheme(this);
    setContentView(R.layout.activity_scouting);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });
    LinearLayout l = (LinearLayout) findViewById(R.id.mainLinear);
    l.requestFocus();

    //createTheApp();

    Switch colorSwitch = (Switch) findViewById(R.id.team_color);
    colorSwitch.setOnCheckedChangeListener(this);


}

onCheckedChange（）：

    @Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if (isChecked){
        Utils.changeToTheme(this,Utils.THEME_RED);

    } else {
        Utils.changeToTheme(this, Utils.THEME_BLUE);
    }
}

Utils.java - 改编自另一个队列

import android.app.Activity;
import android.content.Intent;

public class Utils
{
    private static int sTheme = 2;
    public final static int THEME_RED = 1;
    public final static int THEME_BLUE = 2;

    public static void changeToTheme(Activity activity, int theme)
    {
        sTheme = theme;
        activity.recreate();
    }
    /** Set the theme of the activity, according to the configuration. */
    public static void onActivityCreateSetTheme(Activity activity)
    {
        switch (sTheme)
        {
            default:
            case THEME_BLUE:
                activity.setTheme(R.style.BlueTheme);
                break;
            case THEME_RED:
                activity.setTheme(R.style.RedTheme);
                break;
        }
    }
}

Styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->

    <item name="colorPrimaryDark">@color/colorBluePrimaryDark</item>

<style name="RedTheme" parent="AppTheme.NoActionBar" >
    <item name="colorPrimary">@color/colorRedPrimary</item>
    <item name="colorPrimaryDark">@color/colorRedPrimaryDark</item>
    <item name="colorAccent">@color/colorRedAccent</item>

Answer 1

我认为问题在于这个方法

     @Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if (isChecked){
        Utils.changeToTheme(this,Utils.THEME_RED);
        //Assign isChecked = false;

    } else {
        Utils.changeToTheme(this, Utils.THEME_BLUE);
        // Assign isChecked = true;
    }
}

重新创建活动会导致无限循环
