내 메인 윈도우에서 팝업 창을 표시하는 방법은 무엇입니까?

Question

안녕하세요 친구 한 팝업 창이 샘플 소스 코드를 다운로드 ... 그 작동 좋아요 ...이 응용 프로그램 에뮬레이터 화면을 실행하면 하나의 버튼을, 그 버튼을 클릭하면 팝업 창이 bottom.if에 표시된 동일한 버튼을 다시 클릭하십시오 팝업 창을 닫습니다 ...하지만,

내 응용 프로그램을 열 때 정적 팝업 창이 필요하면이 버튼이 필요하지 않습니다.

package popupTest.popupTest; 

import android.R.layout; 
import android.app.Activity; 
import android.content.Context; 
import android.os.Bundle; 
import android.view.Gravity;

import android.view.View.OnClickListener; 
import android.view.ViewGroup.LayoutParams; 
import android.widget.Button; 
import android.widget.LinearLayout; 
import android.widget.PopupWindow; 
import android.widget.TextView; 

public class popupTest extends Activity { 

PopupWindow popUp; 
LinearLayout layout; 
TextView tv; 
LayoutParams params; 
LinearLayout mainLayout; 
Button but; 
boolean click = true; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    popUp = new PopupWindow(this); 
    layout = new LinearLayout(this); 
    mainLayout = new LinearLayout(this); 
    tv = new TextView(this); 
    but = new Button(this); 
    but.setText("Click Me"); 
    but.setOnClickListener(new OnClickListener() { 

    public void onClick(View v) { 
    if (click) { 
    popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10); 
    popUp.update(50, 50, 300, 80); 
    click = false; 
    } else { 
    popUp.dismiss(); 
    click = true; 
    } 
    } 

    }); 
    params = new LayoutParams(LayoutParams.WRAP_CONTENT, 
    LayoutParams.WRAP_CONTENT); 
    layout.setOrientation(LinearLayout.VERTICAL); 
    tv.setText("Hi this is a sample text for popup window"); 
    layout.addView(tv, params); 
    popUp.setContentView(layout); 
    // popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10); 
    mainLayout.addView(but, params); 
    setContentView(mainLayout); 
} 
}

I 전자가 .. onCreate에 onClick 외부 코드를 넣어 .... 통해 UR 팝업을 제거하는 setOnclickListener를 사용 코드를 dited 그리고 활동의 시작에 팝업을 표시됩니다 :

package popupTest.popupTest; 

import android.R.layout; 
import android.app.Activity; 
import android.content.Context; 
import android.os.Bundle; 
import android.view.Gravity; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.ViewGroup.LayoutParams; 
import android.widget.Button; 
import android.widget.LinearLayout; 
import android.widget.PopupWindow; 
import android.widget.TextView; 

public class popupTest extends Activity { 

PopupWindow popUp; 
LinearLayout layout; 
TextView tv; 
LayoutParams params; 
LinearLayout mainLayout; 
Button but; 
boolean click = true; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    popUp = new PopupWindow(this); 
    layout = new LinearLayout(this); 
    mainLayout = new LinearLayout(this); 
    tv = new TextView(this); 
    but = new Button(this); 
    but.setText("Click Me"); 



    params = new LayoutParams(LayoutParams.WRAP_CONTENT, 
    LayoutParams.WRAP_CONTENT); 
    layout.setOrientation(LinearLayout.VERTICAL); 
    tv.setText("Hi this is a sample text for popup window"); 
    layout.addView(tv, params); 
    popUp.setContentView(layout); 
    // popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10); 
    mainLayout.addView(but, params); 
    setContentView(mainLayout); 

    Handler handler = new Handler(); 
     handler.postDelayed(new Runnable(){ 

     public void run() { 
      // TODO Auto-generated method stub 
      popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10); 
      popUp.update(50, 50, 300, 80); 
     } 

     }, 1000); 
    //Use this to dismiss as per your need... 
    // popUp.dismiss(); 

} 
@Override 
    public boolean onKeyDown(int keyCode, KeyEvent event) { 
     popUp.dismiss(); 
     return false; 

    } 
}
