package com.example.ation02.baseapp;   import android.content.Intent; import android.net.Uri; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.ImageView; import android.widget.RadioButton; import android.widget.RadioGroup; import android.widget.Toast;   public class MainActivity extends AppCompatActivity {     EditText et;     Button btn1,btn2;     RadioGroup RG;     RadioButton Rbtn1, Rbtn2;     ImageView iv;       @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         et = (EditText)findViewById(R.id.et);         btn1 = (Button)findViewById(R.id.btn1);         btn2 = (Button)findViewById(R.id.btn2);         RG = (RadioGroup)findViewById(R.id.RG);         Rbtn1 = (RadioButton)findViewById(R.id.Rbtn1);         Rbtn2 = (RadioButton)findViewById(R.id.Rbtn2);         iv = (ImageView)findViewById(R.id.iv);           btn1.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 String inPutText = et.getText().toString();                 Toast.makeText(MainActivity.this,inPutText,Toast.LENGTH_SHORT).show();             }});           btn2.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 String inPutText = et.getText().toString();                 Toast.makeText(MainActivity.this,inPutText,Toast.LENGTH_SHORT).show();                 Intent mIntent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://"+inPutText));                 startActivity(mIntent);             }});         RG.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {             @Override             public void onCheckedChanged(RadioGroup group, int checkedId) {                 switch (checkedId){                     case R.id.btn1:                     iv.setImageResource(R.drawable.oreo1);                     break;                     case R.id.btn2:                     iv.setImageResource(R.drawable.oreo2);                     break;                 }             }         });         };     } 위와같이 한번 코딩을 짜봤습니다만 라디오버튼을 누르면 이미지가 보여야하는데 라디오 버튼만 눌리고 이미지는 나오지않아 질문합니다. 구동화면도 첨부하겠습니다.

activity_main.xml 구성 문제일 듯 하니, activity_main.xml 정보를 올려 주세요.

추가적으로 로그캣에서  Couldn't load memtrack module, failed to get memory consumption info: -1 와 같은 에러가 반복되는데 구글이랑 네이버에서 검색하는데도 안나오네요...
