Question

我有一个主要活动（mottoscreen），之后会打开一个名为circle的活动，然后从该活动中打开其他两个活动之一（sc_activity和or_activity）。我已经为它编写了代码，但是当点击圈子活动中的按钮时，下一个活动没有显示出来。

圈子Java文件 -

package com.apsdevelopers.mr.meteout;

import android.content.Intent;
import android.os.Bundle;
import android.view.MenuItem;
import android.view.View;
public class circles extends mottoscreen {

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

public void onButtonClick(View v)
{

    if (v.getId() == R.id.GOsc)
    {
        Intent I = new Intent(circles.this, sc_activity.class);
        startActivity(I);
    }

   else if (v.getId() == R.id.GOor)
    {
        Intent j = new Intent(circles.this, or_activity.class);
        startActivity(j);
    }


}

}

Sc_activity Java文件 -

package com.apsdevelopers.mr.meteout;

import android.app.PendingIntent;

import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.Menu;

import android.widget.EditText;
import android.widget.Toast;
public class sc_activity extends mottoscreen
{
    EditText name, ph, address, mass, thing;
    Button msg;

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

    name = (EditText)findViewById(R.id.name);
    EditText p = (EditText)findViewById(R.id.pin);
    String pinc = p.getText().toString();
    final int apsnumber= Integer.parseInt("8763597264");

    if (pinc.equals("753001") || pinc.equals("753002") || pinc.equals("753003") || pinc.equals("753004") || pinc.equals("753005") || pinc.equals("753006") || pinc.equals("753007") || pinc.equals("753008") || pinc.equals("753009")) {
        ph = (EditText)findViewById(R.id.ph);
        address = (EditText)findViewById(R.id.address);
        mass = (EditText)findViewById(R.id.mass);
        thing = (EditText)findViewById(R.id.thing);
        msg = (Button)findViewById(R.id.msg);
        msg.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {
                String number = ph.getText().toString();
                String message1 = name.getText().toString();
                String message2 = address.getText().toString();
                String message3 = mass.getText().toString();
                String message4 = thing.getText().toString();
                Intent i = new Intent(getApplicationContext(), sc_activity.class);
                PendingIntent pIntent = PendingIntent.getActivity(getApplicationContext(), 0, i, 0);
                SmsManager sms = SmsManager.getDefault();
                sms.sendTextMessage(String.valueOf(apsnumber), null, number+message1 + message2 + message3 + message4, pIntent, null);
                Toast.makeText(getApplicationContext(), "Form sent successfully ! , now click on DONE",
                        Toast.LENGTH_LONG).show();
            }
        });
    }
    else
    {
        Toast.makeText(getApplicationContext(), "ERROR: WE DONOT COVER THE PINCODE ENTERED BY YOU, PLZ ENTER A VALID PINCODE OF (CTC, ODISHA)",
                Toast.LENGTH_LONG).show();

    }

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    return true;

}
public void onButtonClick(View v)
{

    if (v.getId() == R.id.msg)
    {
        Intent I = new Intent(sc_activity.this, th_activity.class);
        startActivity(I);
    }


}

请指导我在代码中出错的地方。

Answer 1

请您在代码中查看以下内容：

您的circles.xml有两个ID为GOsc和GOor的按钮？
在您的circles.xml中，您为两个按钮设置了android:onClick="onButtonClick"？
如果以上两个结果都是肯定的，那么您也可以在这里粘贴您的circles.xml文件吗？

从其他活动中打开活动
