LinearLayout dualmodeLayout = (LinearLayout) inflater.inflate(R.layout.dual_mode,null).findViewById(R.id.dualmodelayout);

〈三〉

setLayoutParams：子布局在设置在父布局中

private FrameLayout.LayoutParams params = null;

params = new FrameLayout.LayoutParams(88, 300, Gravity.RIGHT
                    | Gravity.BOTTOM);
            params.bottomMargin = playControlLayout.getHeight()
                    - bt_dualMode.getHeight();
            params.rightMargin = (screenWidth - playControlLayout.getWidth())
                    / 2 + bt_dualMode.getHeight() - 26;
            Log.i(TAG, "**showDualModeLayout**" + " "
                    + params.bottomMargin + " " + params.rightMargin + " "
                    + bt_dualMode.getBottom());
            dualmodeLayout.setLayoutParams(params);

dualmodeLaypout 是子布局，params是父布局

插入到主界面中

activityLayout.addView(dualmodeLayout, params);

希望显示出来

dualmodeLayout.setVisibility(View.VISIBLE);

希望不显示

dualmodeLayout.setVisibility(View.INVISIBLE);
