1.这是First Activity xml文件。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

2.这是First Activity java文件。
package com.example.himanshu.checkbox_module;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
intentData = new Intent(FirstActivity.this,SecondActivity.class);
buttonSend = (Button) findViewById(R.id.button1);
buttonSend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(intentData);
}
});
}
public void onCheckedBox(View view){
boolean checked = ((CheckBox)view).isChecked();
switch (view.getId()){
case R.id.mon:if (checked){
intentData.putExtra("MON","Monday");
}else {

3.这是第二个活动xml文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
4.这是第二个活动java文件。
package com.example.himanshu.checkbox_module;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
public class SecondActivity extends AppCompatActivity {
TextView showResult;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_secon);
showResult = (TextView) findViewById(R.id.textview_result);
Intent intentResult = this.getIntent();
String monday = intentResult.getStringExtra("MON");
String tuesday = intentResult.getStringExtra("TUE");
String wednesday = intentResult.getStringExtra("WED");
String thursday = intentResult.getStringExtra("THU");
String friday = intentResult.getStringExtra("FRI");
String saturday = intentResult.getStringExtra("SAT");
String sunday = intentResult.getStringExtra("SUN");
showResult.setText(monday+" , "+tuesday+" , "+wednesday+" , "+thursday+" , "+friday+", "+saturday+" , "+sunday);
}
}
答案 0 :(得分：5)
boolean isChecked = myCheckBox.isChecked();
Intent i = new Intent(this, secondActivity.class);
i.putExtra("checkBoxValue", isChecked);
startActivity(i);
在您的第二个活动onCreate
boolean isChecked = this.getIntent().getBooleanExtra("checkBoxValue", false);
