AlertDialog自訂關閉

標籤：style   os   cti   re   c   line   

    如果AlertDialog裡有輸入框，那麼如何根據自己的需要關閉AlertDialog，網上有很多是通過反射方式。這裡有另外一種方法。

Builder builder = new Builder(MainActivity.this);

builder.setTitle("伺服器設定");

LayoutInflater inflater = LayoutInflater.from(this);

final View view = inflater.inflate(R.layout.edit, null);

builder.setView(view);

builder.setPositiveButton(R.string.ok, new AlertDialog.OnClickListener(){

@Override

public void onClick(DialogInterface dialog, int which) {

}

});

builder.setNegativeButton(R.string.cancel, new AlertDialog.OnClickListener(){

@Override

public void onClick(DialogInterface dialog, int which) {

dialog.dismiss();

}

});

final AlertDialog dialog = builder.create();

//builder.show();

dialog.show();

dialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener()

        {            

            @Override

            public void onClick(View v)

            {          

                  Boolean wantToCloseDialog = false;

                //需要時修改wantToCloseDialog的值

                 if(wantToCloseDialog){

                     dialog.dismiss();

                 }else{

                     Toast.makeText(MainActivity.this, "伺服器位址不符合規範", Toast.LENGTH_SHORT).show();

                 }

            }

        });
