構建自定義AlertDialog，如何實現按鈕點擊？

Question

final AlertDialog builder = new AlertDialog.Builder(activity).create(); 
LayoutInflater factory = LayoutInflater.from(activity); 
View view = factory.inflate(R.layout.inventory_item_pop_up, null); 
builder.setView(view); 

ImageButton discardButton = (ImageButton) view.findViewById(R.id.popup_discard); 

discardButton.setClickable(true); 
discardButton.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     listener.remove(f); 
     builder.dismiss(); 
    } 
}); 

此按鈕點擊根本沒有響應。我怎樣才能使這段代碼工作？順便說一句，我在適配器中使用這段代碼。

Answer 1

好了，這是尷尬的...該代碼是正確的，我只是不調用正確的createDialog（）方法。

Answer 2

the onCLickListener您已註冊，是DialogInterface.OnClickListener？如果您使用View類中的onCLickListener，那麼這不起作用。請重新檢查。

你需要做的

discardButton.setOnClickListener(new DialogInterface.OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     listener.remove(f); 
     builder.dismiss(); 
    } 
});

我希望這對你有幫助。我實現這種方式的自定義對話框

public void showUpdateDialog() { 
    updateDialog = new Dialog(this, 
      android.R.style.Theme_Translucent_NoTitleBar_Fullscreen) { 
     @Override 
     public void onBackPressed() { 
      this.dismiss(); 
      loadDataAsync.execute(); 

     } 
    }; 

    updateDialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    updateDialog.getWindow().setFlags(
      WindowManager.LayoutParams.FLAG_FULLSCREEN, 
      WindowManager.LayoutParams.FLAG_FULLSCREEN); 

    updateDialog.setContentView(R.layout.updatepopup); 
    logger.info("Network error popup on"); 
    updateDialog.setCancelable(true); 

    ImageView dialogImage = (ImageView) updateDialog 
      .findViewById(R.id.dialogheaderimageupdateupdate); 

    dialogImage.setBackgroundResource(R.drawable.infoimage); 

    TextView dialogMesage = (TextView) updateDialog 
      .findViewById(R.id.dialogmessgetextupdate); 
    TextView currVersion = (TextView) updateDialog 
      .findViewById(R.id.currentversionupdate); 
    TextView newVersion = (TextView) updateDialog 
      .findViewById(R.id.newversionupdate); 
    TextView dialogHeader = (TextView) updateDialog 
      .findViewById(R.id.dialogheadertextupdate); 

    newVersion.setText("Latest version: " + versionCode); 
    currVersion.setText("Current version : " + currentVersionName); 
    dialogMesage.setText("Would you like to update now?"); 
    dialogHeader.setText("A program update is available! "); 

    Button dialogOk = (Button) updateDialog 
      .findViewById(R.id.dialogokbuttonupdate); 
    dialogOk.setText("Update"); 
    dialogOk.setFocusable(true); 
    dialogOk.requestFocus(); 
    dialogOk.setFocusableInTouchMode(true); 
    dialogOk.requestFocus(); 

    Button dialogCancel = (Button) updateDialog 
      .findViewById(R.id.dialogcancelbuttonupdate); 
    dialogOk.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      updateDialog.dismiss(); 
      downLoad = new DownLoad(); 
      downLoad.execute(apkUrl.trim()); 
     } 
    }); 
    dialogCancel.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      updateDialog.dismiss(); 
      loadDataAsync.execute(); 

     } 
    }); 
    try { 
     updateDialog.show(); 
    } catch (Exception e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
} 

而我updatepopup.xml下方顯示
