感觉今天所学的 radio listcheckbox spinner 基础内容都比较简单
目前只写了单选的信息显示。checkBox 和 Spinner 还没实现
源码如下
（注意要写第二个Activity的清单
即添加Activity02的activity标签）
Activity01Activity
package yzy.cxt.com;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.Toast;
import android.widget.CompoundButton.OnCheckedChangeListener;
public class Activity01Activity extends Activity {
// 定义控件变量
private RadioButton radioButton01;
private RadioButton radioButton02;
private CheckBox cb1;
private CheckBox cb2;
private CheckBox cb3;
private CheckBox cb4;
private EditText editText;
private Button button;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.one_layout);
// 绑定变量
radioButton01 = (RadioButton) findViewById(R.id.radiobutton01);
radioButton02 = (RadioButton) findViewById(R.id.radiobutton02);
cb1 = (CheckBox) findViewById(R.id.cb1);
cb2 = (CheckBox) findViewById(R.id.cb2);
cb3 = (CheckBox) findViewById(R.id.cb3);
cb4 = (CheckBox) findViewById(R.id.cb4);
editText = (EditText) findViewById(R.id.edit);
button = (Button) findViewById(R.id.button);
// 为radioButton01设置监听事件
radioButton01.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
radioButton01.setChecked(isChecked);
if (radioButton02.isChecked()) {
radioButton02.setChecked(false);
}
}
});
// 为radioButton02设置监听事件
radioButton02.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
radioButton02.setChecked(isChecked);
if (radioButton01.isChecked()) {
radioButton01.setChecked(false);
}
}
});
// 为Button设置监听事件
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
String quantityType = "";
String descri = "";
String db = "";
// 获取信息
if (radioButton01.isChecked() && !radioButton02.isChecked()) {
quantityType = "twenty";
} else if (radioButton02.isChecked()
&& !radioButton01.isChecked()) {
quantityType = "thirty";
} else {
Toast.makeText(Activity01Activity.this, "请正确选择",
Toast.LENGTH_LONG);
}
descri = editText.getText().toString();
// 将信息放入Bundle
Bundle bundle = new Bundle();
bundle.putString("quantityType", quantityType);
bundle.putString("desc", descri);
Intent intent = new Intent();
intent.setClass(Activity01Activity.this, Activity02.class);
intent.putExtras(bundle);
// 开始。。。。跳转
startActivity(intent);
}
});
}
}
Activity02
package yzy.cxt.com;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class Activity02 extends Activity{
private TextView message;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.two_layout);
Bundle bundle = this.getIntent().getExtras();
String quantity = "";
// 接收信息并显示
message = (TextView)findViewById(R.id.message);
String quantityType = bundle.getString("quantityType");
String desc = bundle.getString("desc");
// 判断
if ("twenty".equals(quantityType)) {
quantity = "20";
} else {
quantity = "30";
}
message.setText("你选择的每页帖数是" + quantity + ", 您对本站的看法为：" + desc);
}
}
