AlertDialog full customize
===
此範例可以完全客製化自己想要的 `alert` 畫面，建立好自己的 `layout` 檔，再利用 `AlertDialog.Builder` 將畫面呈現出來：


public void create_dialog() {

    AlertDialog.Builder mBuilder = new AlertDialog.Builder(this);

    // 建立的 layout 檔
    View mView = getLayoutInflater().inflate(R.layout.dialog_layout_add_couser, null);

    final EditText et_input = (EditText) mView.findViewById(R.id.et_addCoUser);
    Button btn_yes = (Button) mView.findViewById(R.id.btn_addCoUser_yes);
    Button btn_no = (Button) mView.findViewById(R.id.btn_addCoUser_no);

    mBuilder.setView(mView);
    final AlertDialog alertDialog = mBuilder.create();

    btn_yes.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick (View view) {
            String msg = et_input.getText().toString();
            Toast.makeText(CoManageActivity.this, "YES, " + msg, Toast.LENGTH_LONG).show();
            alertDialog.dismiss();
        }
    });

    btn_no.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick (View view) {
            Toast.makeText(CoManageActivity.this, "NO", Toast.LENGTH_LONG).show();
            alertDialog.dismiss();
            alertDialog.dismiss();
        }
    });

    alertDialog.show();

}
