Вставить значение переключателя в базу данных

Question

Я хочу создать приложение, которое может собирать информацию людей и добавлять в базу данных. Но у меня есть некоторая проблема с введением выбранного значения радиообъекта в базу данных.

public class MainActivity extends Activity { 
    SQLiteDatabase pf; 

    TableRow tablerow; 
    TextView t,t1,t2,t3,t4,t5;  
    String first_name,last_name; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    pf=openOrCreateDatabase("Profile",MODE_PRIVATE,null); 
    pf.execSQL("CREATE TABLE IF NOT EXISTS Persone(first_name VARCHAR,last_name VARCHAR,Usergender VARCHAR);"); 
} 

public void RadioButtonClicked(View view) { 

    //This variable will store whether the user was male or female 
    String userGender=""; 
    // Check that the button is now checked? 
    boolean checked = ((RadioButton) view).isChecked(); 

    // Check which radio button was clicked 
    switch(view.getId()) { 
     case R.id.radio_female: 
      if (checked) 
       userGender = "female"; 
      break; 
     case R.id.radio_male: 
      if (checked) 
       userGender = "male"; 
      break; 
    } 
    pf.execSQL("INSER INTO Persone VALUES('"+userGender+"');"); 
} 

public void add(View view){ 
    EditText fn = (EditText)findViewById(R.id.first_name); 
    EditText ln = (EditText)findViewById(R.id.last_name); 

    first_name=fn.getText().toString(); 
    last_name =ln.getText().toString(); 

    pf.execSQL("INSERT INTO Persone VALUES('"+first_name+"','"+last_name+"');"); 
} 



public void show(View view){ 
    Cursor c = pf.rawQuery("SELECT * FROM Persone", null); 
    int count = c.getCount(); 
    c.moveToFirst(); 
    TableLayout tablelayout = new TableLayout(getApplicationContext()); 
    tablelayout.setVerticalScrollBarEnabled(true); 
    TableRow tablerow; 
    TextView t,t1,t2,t3,t4,t5; 
    tablerow = new TableRow(getApplicationContext()); 

    t = new TextView(getApplicationContext()); 
    t.setText("First Name"); 
    t.setTextColor(Color.RED); 
    t.setTypeface(null,Typeface.BOLD); 
    t.setPadding(20,20,20,20); 
    tablerow.addView(t); 

    t3 = new TextView(getApplicationContext()); 
    t3.setText("Last Name"); 
    t3.setTextColor(Color.RED); 
    t3.setTypeface(null,Typeface.BOLD); 
    t3.setPadding(20,20,20,20); 
    tablerow.addView(t3); 

    t4 = new TextView(getApplicationContext()); 
    t4.setText("Gender"); 
    t4.setTextColor(Color.RED); 
    t4.setTypeface(null,Typeface.BOLD); 
    t4.setPadding(20,20,20,20); 
    tablerow.addView(t4); 

    tablelayout.addView(tablerow); 
    for(Integer j = 0;j<count;j++) 
    { 
     tablerow = new TableRow(getApplicationContext()); 

     t1 = new TextView(getApplicationContext()); 
     t1.setText(c.getString(c.getColumnIndex("first_name"))); 
     t1.setPadding(20, 20, 20, 20); 


     t2 = new TextView(getApplicationContext()); 
     t2.setText(c.getString(c.getColumnIndex("last_name"))); 
     t2.setPadding(20, 20, 20, 20); 

     t5 = new TextView(getApplicationContext()); 
     t5.setText(c.getString(c.getColumnIndex("userGender"))); 
     t5.setPadding(20, 20, 20, 20); 



     tablerow.addView(t1); 
     tablerow.addView(t2); 
     tablerow.addView(t5); 


     tablelayout.addView(tablerow); 

     c.moveToNext(); 
    } 
    setContentView(tablelayout); 
    pf.close(); 
}

Я хочу, чтобы получить значение выбранной радиокнопки и добавить его в базу данных. Но когда я бегу Android симулятор и программу, она говорит:

, к сожалению, MyThirdApp остановил

Может кто-нибудь мне помочь?

Answer 1

Привет там не проблема:

Во-первых добавить:

android:onClick="RadioButtonClicked" > 

под оба ваших мужских и женских RadioGroup дочерних элементов Как так:

android:id="@+id/radio_female" 
android:text="@string/radio_female" 
android:onClick="RadioButtonClicked" 

Теперь, когда это будет сделано, в вашем MainActivity добавить этот код:

//Note the name of the method must match the xml onClick value in this case 'RadioButtonClicked' 

public void RadioButtonClicked(View view) { 

//This variable will store whether the user was male or female 
String userGender=""; 
// Check that the button is now checked? 
boolean checked = ((RadioButton) view).isChecked(); 

// Check which radio button was clicked 
switch(view.getId()) { 
    case R.id.radio_female: 
     if (checked) 
      userGender = "female"; 
     break; 
    case R.id.radio_male: 
     if (checked) 
      userGender = "male"; 
     break; 
} 

//Now insert it into your database using userGender instead of gender 

pf.execSQL....+userGender 

}
