如何選擇單選按鈕將圖像加載到imageView

Question

嗨我正在做一個學校項目，我正在做一個性別分類。如果我選擇男性，男性圖標應加載到我的android應用程序中的imageView和Vice Versa。

public static TextView lable5,lable7; 
public static SeekBar SB1,SB2; 
public static RadioButton RB1,RB2; 
public static ImageView IV1; 

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

    lable5 = (TextView) findViewById(R.id.textView5); //this is for seekbar1 
    lable7 = (TextView) findViewById(R.id.textView7); //This is for seekbar2 
    RB1 = (RadioButton) findViewById(R.id.radioButton1); // This is for male option 
    RB2 = (RadioButton) findViewById(R.id.radioButton2); // This is for Female Option 
    IV1 = (ImageView) findViewById(R.id.imageView); // This is the only imageView available 


    SB1=(SeekBar) findViewById(R.id.seekBar1);// This is for seekBar1 
    SB2=(SeekBar) findViewById(R.id.seekBar2);//This is for seekBar2 
    lable5.setText(String.valueOf(SB1.getProgress())); 
}

假設你添加的單選按鈕在RadioGroup你可以做到以下幾點：

group = (RadioGroup) findViewById(R.id.radioGroup); 
group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(RadioGroup group, int checkedId) { 
    switch(checkedId) { 
     case R.id.radioButton1: 
     IV1.setImageResource(R.drawable.male_icon); 
     break; 
     case R.id.radioButton2: 
     IV1.setImageResource(R.drawable.female_icon); 
     break; 
     default: 
     break; 
    } 
    } 
}); 

如果你的單選按鈕在RadioGroup你可以用這樣的代碼添加他們：

<RadioGroup 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:id="@+id/radioGroup" > 
    <RadioButton ... /> 
    <RadioButton ... /> 
</RadioGroup> 

如果您在使用我的代碼時遇到問題，請發表評論，我會幫您。
