java-將一個button放左邊另一個放右邊

將一個button放左邊另一個放右邊

創建了動態linearlayout。創建了兩個button：

LinearLayout layout = new LinearLayout(this);
        layout.setOrientation(LinearLayout.HORIZONTAL);
        layout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                LayoutParams.FILL_PARENT));

        TextView titleView = new TextView(this);
        titleView.setWidth(LayoutParams.WRAP_CONTENT);
        titleView.setHeight(LayoutParams.WRAP_CONTENT);
        titleView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        titleView.setText("Hallo Welt!");
        layout.addView(titleView);

        Button btnConnect = new Button(this);
        btnConnect.setText("Connect");
        layout.addView(btnConnect);

    Button btnDisconnect = new Button(this);
    btnDisconnect.setText("Disconnect");
    layout.addView(btnDisconnect);

我想將鏈接的button放到左角，沒鏈接的button放到右角，不知道能不能實現？
謝謝：D

最佳回答：

試試設置button布局

LayoutParams params;

Button btnConnect = new Button(this);
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.Left;
btnConnect.setLayoutParams(params);
...
Button btnDisconnect = new Button(this);
params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.Right;
btnConnect.setLayoutParams(params);
