我在android中做了一個簡單的應用程序，其中有兩個活動，第一個活動，它是一個包含一些editexts和radio組以及checkbox的表單。但是我有單選按鈕的問題。另一個activity.i已經試過如下：radiogroup在android中不工作

act1.java

package com.example.myweb; 

import android.os.Bundle; 
import android.app.Activity; 
import android.content.Intent; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.CheckBox; 
import android.widget.CompoundButton; 
import android.widget.CompoundButton.OnCheckedChangeListener; 
import android.widget.EditText; 
import android.widget.RadioButton; 
import android.widget.RadioGroup; 
import android.widget.Toast; 

public class MainActivity extends Activity { 
    public String EXTRA_MESSAGE = "com.example.myweb"; 
    Button b; 
    EditText ed1,ed2,ed3,ed4; 
    RadioGroup rg; 
    RadioButton rb; 
    CheckBox c1; 
    // boolean yes = c1.isChecked(); 


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

    rg=(RadioGroup)findViewById(R.id.radioGroup1); 
     b =(Button)findViewById(R.id.send); 
     ed1=(EditText)findViewById(R.id.edit_msg); 
     ed2=(EditText)findViewById(R.id.edit_msg1); 
     ed3=(EditText)findViewById(R.id.edit_msg3); 
     ed4=(EditText)findViewById(R.id.edit_msg4); 
     // r1=(RadioButton)findViewById(R.id.radioButton1); 
     // r2=(RadioButton)findViewById(R.id.radioButton2); 
     c1=(CheckBox)findViewById(R.id.ck1); 
     int id=rg.getCheckedRadioButtonId(); 
     rb=(RadioButton)findViewById(id); 
       b.setOnClickListener(new OnClickListener() { 

        @Override 
        public void onClick(View v) { 
         // TODO Auto-generated method stub 


         // Intent i = new Intent(MainActivity.this,Act2.class); 
        Bundle b=new Bundle(); 
        final String fname=ed1.getText().toString(); 
        final String lname=ed2.getText().toString(); 
        final String fon=ed3.getText().toString(); 
        final String city= ed4.getText().toString(); 
        final String gen = rb.getText().toString(); 
        if(c1.isChecked()){ 



           Intent i = new Intent(MainActivity.this,Act2.class); 

           i.putExtra("Extra__fname", fname); 
           i.putExtra("Extra__lname", lname); 
           i.putExtra("Extra__fon", fon); 
           i.putExtra("Extra__city", city); 
           i.putExtra("gen", gen); 
           startActivity(i); 
        } 
        else{ 

         Toast.makeText(getApplicationContext(), "Please accept it", 1).show(); 
          } 
        }  
        }); 
        } 
}

act2.java

package com.example.myweb; 

import org.w3c.dom.Text; 

import android.os.Bundle; 
import android.app.Activity; 
import android.content.Intent; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.TextView; 

public class Act2 extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.act2); 
     TextView t = (TextView)findViewById(R.id.tv1); 
     TextView t1 = (TextView)findViewById(R.id.tv2); 
     TextView t2 = (TextView)findViewById(R.id.tv3); 
     TextView t3 = (TextView)findViewById(R.id.tv4); 
     TextView t4 = (TextView)findViewById(R.id.tv5); 
     Bundle bundle = getIntent().getExtras(); 

      String fname= bundle.getString("Extra__fname"); 
       String lname= bundle.getString("Extra__lname"); 
       String fon= bundle.getString("Extra__fon"); 
       String city= bundle.getString("Extra__city"); 
       String gen= bundle.getString("gen"); 
       t.setText(fname); 
       t1.setText(lname); 
       t2.setText(fon); 
       t3.setText(city); 
       t4.setText(gen); 

       } 
     }

檢索它的關鍵應該是相同的

 i.putExtra("gen", gen);

其

String gen= bundle.getString("Extra_gen");

應該

String gen= bundle.getString("gen");

編輯：

您正在使用getApplicationContext（）。而是使用一個活動場景

Toast.makeText(getApplicationContext(), "Please accept it", 1).show();

要知道什麼時候使用應用程序上下文以及何時使用活動情境，通過commonsware在下面的鏈接

When to call activity context OR application context?

Toast.makeText(act1.this, "Please accept it", 1).show();

使用

String gen= bundle.getString("gen");

你需要像這樣

rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
    void onCheckedChanged(RadioGroup rg, int checkedId) { 
      for(int i=0; i<rg.getChildCount(); i++) { 
       RadioButton btn = (RadioButton) rg.getChildAt(i); 
       if(btn.getId() == checkedId) { 
        String text = btn.getText(); 
        // do something with text 
        return; 
       } 
      } 
    } 
});

（OR）

當你需要獲得所選擇的無線選項。

int id = rg.getCheckedRadioButtonId(); 
if (id == -1){ 
    //no item selected 
} 
else{ 
if (id == R.id.radio_button1){ 
    //Do something with the button 
} 
}

對radioGroup使用setOnCheckedChangeListener。爲RadioGroup其中包含兩個RadioButtons

radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() { 

     public void onCheckedChanged(RadioGroup arg0, int arg1) { 

      radioButton = (RadioButton) findViewById(radioGroup 
        .getCheckedRadioButtonId()); 
      if (radioButton.getText().equals("Name")) { 
       // code for first radioButton 
      } else { 
       // code for second radioButton     
      } 
     } 
    });

示例代碼我希望這會幫助你。的

使用

String gen= bundle.getString("gen");

代替

String gen= bundle.getString("Extra_gen");

檢索選自意圖RadioButton值從先前的活動sended。因爲您發送單選價值與gen關鍵，但嘗試使用Extra_gen

int radioButtonID = rg.getCheckedRadioButtonId(); 
View radioButton = rg.findViewById(radioButtonID);

String gen="male"; 

if(index==0) 
gen="male"; 
else 
gen="female"; 

.... 

i.putExtra("gen", gen); 
startActivity(i);

檢查答案請確保您的activity_main.xml男性的索引號爲0.
