[Android]setContentView切換layout

如果單純要切換layout，利用setContentView就可以做到啦

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class test extends Activity {
	
	Button connect = null;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //設定layout
        setLayout(1);
    }
    
    public void setLayout(int layout_num){
    	//layout1
    	if(layout_num == 1) {
    		setContentView(R.layout.layout1);
    		connect = (Button) findViewById( R.id.connect);
    		//點擊按鈕後更換layout
    		connect.setOnClickListener(new OnClickListener(){
    			public void onClick(View v){
    				setLayout(2);
    			}
    		});
    	}
    	//layout2
    	else{
    		setContentView(R.layout.layout2);
    	}
    }
}
