這是TQC的203題，

程式碼為自行撰寫，

僅供參考。

 

主要是要練習轉型，

由NT轉US。

 

package COM.TQC.GDD02;

import java.text.DecimalFormat;
import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class GDD02 extends Activity {
	public static final String PREF_ExchangeRate = "Exchange_Rate" ;
    private Button calcbutton ;
	private EditText fieldExchangeRate ;
	private EditText fieldNTD ;
	private TextView infoView;
	
	/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
    	
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        findview();
        setlistener();   
    }
    
    public void findview()
    {
    	 calcbutton=(Button)findViewById(R.id.button1); 
         fieldExchangeRate=(EditText) findViewById(R.id.editText1);
         fieldNTD=(EditText) findViewById(R.id.editText2);
         infoView= (TextView)findViewById(R.id.textView3);
    }
    
    public void setlistener()
    {
    	calcbutton.setOnClickListener(new Button.OnClickListener(){
			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				Convert1();
			}});
    }
    
    private void Convert1()
    {
    	double _Con1=Double.parseDouble(fieldExchangeRate.getText().toString())*Double.parseDouble(fieldNTD.getText().toString());
    	infoView.setText(String.valueOf(_Con1));
    }
    
    public void onStop() {
    	super.onStop() ;
    	SharedPreferences settings = getSharedPreferences(PREF_ExchangeRate, 0);
    	settings.edit().putString(PREF_ExchangeRate, fieldExchangeRate.getText().toString()).commit() ;
    	
    }

}
