Java 如何把一个钮扣放在右边，另一个钮扣放在左边

我尝试动态创建linerlayout，并创建了两个按钮

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);

我想把连接按钮放在左角，把DISCONET按钮放在右角。我该怎么做呢？

您是否尝试过为按钮设置布局重力

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);
...

布局重力定义在其父视图中放置视图的位置（另请参见）

干杯

您可以使用RelativeLayout而不是线性布局

并将规则添加到 RelativeLayout.Layoutparams参数=

RelativeLayout.Layoutparams参数=（RelativeLayout.Layoutparams）按钮。getLayoutParams（）；
params.addRule（RelativeLayout.ALIGN\u PARENT\u RIGHT）
