public class MainActivity extends Activity {

    Button button3;

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    public void addListenerOnButton() {
        final Context context = this;

        button3 = (Button) findViewById(R.id.fishguide);

        button3.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {

                Intent intent = new Intent(context, PageThree.class);

                startActivity(intent);

            }

        });

    }

}

PageThree.java

package com.d.di;

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

public class PageThree extends Activity {

    Button button3;

    @Override

我做了第三页，它运行但是它错了

MainActivity2.java

package com.d.di;


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

public class MainActivity2 extends Activity {

    Button fishlink;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fishguide);
        addListenerOnButton();
    }

    public void addListenerOnButton() {
        final Context context = this;
        fishlink = (Button) findViewById(R.id.fish);

        fishlink.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                Intent intent = new Intent(context, PageFish.class);
                startActivity(intent);

            }

        });

    }

}

PageFish.java

package com.d.di;

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

public class PageFish extends Activity {

    Button fishlink;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fish);
    }
}

帮助：）

当我点击“Fish”时，编辑/它将“Fish guide”改为“Fish”，它再次将我带到“Fish”等等，它不会转到第三页！

PageThree.java

package com.d.di;

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

public class PageThree extends Activity {

    Button button3;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fishguide);
        addListenerOnButton();
    }
    public void addListenerOnButton() {
        final Context context = this;

        button3 = (Button) findViewById(R.id.fish);

        button3.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {

                Intent intent = new Intent(context, PageThree.class);

                startActivity(intent);

            }

        });
}
}

Answer 1

您已使用

setContentView(R.layout.fishguide);

PageThree.java中的

将其更改为要在图像中显示第三张图像的xml。比如，third.xml

setContentView(R.layout.third);

你已经完成了。

Answer 2

注意：您一次又一次地获得相同的布局，因为在PageThree.java中您正在使用意图PageThree.java开始活动。相反，只需将其更改为PageFish.java。

因此，当您处于第二个布局（PageThree.java）时，只需在按钮点击时启动第三个布局（PageFish.java）的活动，如下所示 -

<强> PageThree.java

package com.d.di;

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

public class PageThree extends Activity {

    Button button3;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fishguide);

    button3 = (Button) findViewById(R.id.fish);

        button3.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {

                Intent intent = new Intent(PageThree.this, PageFish.class);

                startActivity(intent);

            }

        });

    }
}
