活动之间的更改不起作用

我试图改变我的Android应用程序(2.1-update1)中的活动,但它不起作用。 有什么建议么?

我调试应用程序时发生的唯一情况是,它停在Instrumentation.java中这部分代码上:

public void waitForIdle() {
            synchronized (this) {
                while (!mIdle) {
                    try {
                        wait();
                    } catch (InterruptedException e) {
                    }
                }
            }
        }

Eclipse说它在线程1中

Instrumentation.checkStartActivityResult(int,Object)行:1537.如果我恢复应用程序,下一站是在ZygoteInit.java尝试运行Throwable cause = ex.getCause(); ... Eclipse说ZygoteInit $ MethodAndArgsCaller.run()行:864。

这里是源代码: HappyHomes.java

package com.example.app;

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class HappyHomes extends Activity {
    /**
     * Called when the activity is first created.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button login = (Button) findViewById(R.id.btnLogin);
        login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                ProgressDialog laddRuta = ProgressDialog.show(HappyHomes.this, "",
                        "Loggar in, vänligen vänta...", true);

                Intent myIntent = new Intent(view.getContext(), Kategorier.class);
                myIntent.
                        startActivity(myIntent);
            }
        });
    }
}

Kategorier.java

package com.example.app;

import android.app.Activity;
import android.os.Bundle;

public class Kategorier extends Activity {
    /**
     * Called when the activity is first created.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.kategorier);
    }
}

感谢您的帮助!


确保Kategorier已在你的AndroidManifest.xml文件中注册。


更改myIntent.startActivity(myIntent);HappyHomes.this.startActivity(myIntent);


Intent类中没有任何startActivity()方法。 你一定是做错了。 只需写入startActivity(myIntent)
