Codenameone CN1库-runOnUiThread中无代码激发
本机实现中没有在runOnUiThread中触发代码。RunNuithRead启动前的代码。我肯定我做的事情不对。 我像这样创建了CodenameOne库Codenameone CN1库-runOnUiThread中无代码激发,codenameone,Codenameone,本机实现中没有在runOnUiThread中触发代码。RunNuithRead启动前的代码。我肯定我做的事情不对。 我像这样创建了CodenameOne库 package com.uithread.test; import com.codename1.system.NativeInterface; public interface UIThreadNative extends NativeInterface { public void runNativeCode(); } pac
package com.uithread.test;
import com.codename1.system.NativeInterface;
public interface UIThreadNative extends NativeInterface {
public void runNativeCode();
}
package com.uithread.test;
import com.codename1.system.NativeLookup;
import com.codename1.ui.Dialog;
public class UIThreadManager {
private static UIThreadNative uithreadNative;
public UIThreadManager() {
if (uithreadNative == null) {
uithreadNative = (UIThreadNative) NativeLookup.create(UIThreadNative.class);
if (uithreadNative == null) {
Dialog.show("Null implementation", " UIThread is not implemented yet in this platform.", "Ok", null);
throw new RuntimeException("UIThread is not implemented yet in this platform.");
}
}
if (!uithreadNative.isSupported()) {
Dialog.show("Unsupported", " UIThread is not supported in this platform.", "Ok", null);
throw new RuntimeException("UIThread is not supported in this platform.");
}
}
public void runNativeCode() {
uithreadNative.runNativeCode();
}
}
android的本机实现
package com.uithread.test;
import android.content.Context;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import com.codename1.impl.android.*;
import com.codename1.ui.Dialog;
public class UIThreadNativeImpl {
private static Context context() {
return com.codename1.impl.android.AndroidNativeUtil.getActivity().getApplicationContext();
}
private static Activity activity() {
return com.codename1.impl.android.AndroidNativeUtil.getActivity();
}
public void runNativeCode() {
final Activity convenientActivity = activity();//AndroidNativeUtil.getActivity();
final CodenameOneActivity codenameoneActivity = (CodenameOneActivity) AndroidNativeUtil.getActivity();
final android.app.Activity app = (Activity) AndroidNativeUtil.getActivity();
Dialog.show("Activity", convenientActivity + " convenientActivity", "Ok", null);
Dialog.show("Activity", codenameoneActivity + " codenameoneActivity", "Ok", null);
Dialog.show("Activity", app + " App", "Ok", null);
convenientActivity.runOnUiThread(new Runnable() {
public void run() {
Dialog.show("In run", "Run started", "Ok", null);
}
});
}
public boolean isSupported() {
return true;
}
}
在Statemachine中,我通过单击按钮在代码中运行此命令
@Override
protected void onMain_ButtonAction(Component c, ActionEvent event) {
UIThreadManager uIThreadManager = new UIThreadManager();
uIThreadManager.runNativeCode();
}
正如我刚才所说。runOnUiThread之前的代码工作,但runOnUiThread中的代码不工作。本机实现中runNativeCode中的对话框用于检查不同风格的活动,这正确地显示了不同的风格是相同的
谢谢。本机UI线程与我们的EDT完全不同,因此从该线程显示一个代号为One的对话框将是一个巨大的EDT冲突,可能会导致严重的崩溃 由于我们的对话框可以安全地阻止,因此您将有效地阻止整个应用程序并使其崩溃 我们使用的这一行与您在Codename One和库中编写的内容非常相似,例如:
谢谢。救了我一天。所有android本机代码都能完美启动。
AndroidNativeUtil.getActivity().runOnUiThread(new Runnable() { ... });
