问题描述
如何设置layout_gravity编程的按钮？
我发现这个例子在互联网上，但它只是抛出了我一个空指针异常：
按钮用作MyButton =新的按钮（这一点）;
LinearLayout.LayoutParams LLLP =（LinearLayout.LayoutParams）MyButton.getLayoutParams（）;
lllp.gravity = Gravity.RIGHT;
MyButton.setLayoutParams（LLLP）;
MyLinearLayout.addView（用作MyButton）;
解决方案
LinearLayout.LayoutParams PARAMS =新LinearLayout.LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.FILL_PARENT）;
params.weight = 1.0F;
params.gravity = Gravity.TOP;
button.setLayoutParams（PARAMS）;

How to set layout_gravity programatically for buttons?
I found this example on internet, but its simply throws me a NullPointer exception:
Button MyButton = new Button(this);
LinearLayout.LayoutParams lllp=(LinearLayout.LayoutParams)MyButton.getLayoutParams();
lllp.gravity=Gravity.RIGHT;
MyButton.setLayoutParams(lllp);
MyLinearLayout.addView(MyButton);
解决方案
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT);
params.weight = 1.0f;
params.gravity = Gravity.TOP;
button.setLayoutParams(params);
