我以编程方式进行了以下布局:
LinearLayout progressLayout = new LinearLayout(this);
progressLayout.setOrientation(LinearLayout.VERTICAL);
TextView t = new TextView(this);
t.setText("Test..");
t.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 20);
LayoutParams l = new LayoutParams(android.view.ViewGroup.LayoutParams.WRAP_CONTENT, android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
l.setMargins(10, 10, 10, 25); ===> does not work?
t.setLayoutParams(l);
ProgressBar circle = new ProgressBar(this, null,
android.R.attr.progressBarStyleLarge);
circle.setLayoutParams(new LayoutParams(android.view.ViewGroup.LayoutParams.WRAP_CONTENT, android.view.ViewGroup.LayoutParams.WRAP_CONTENT));
progressLayout.setLayoutParams(new LayoutParams(
android.view.ViewGroup.LayoutParams.FILL_PARENT,
android.view.ViewGroup.LayoutParams.FILL_PARENT));
progressLayout.setGravity(Gravity.CENTER);
progressLayout.addView(t);
progressLayout.addView(circle);
this.setContentView(progressLayout);
但是我在setMargins中作为值没有给出什么,它根本没有任何效果。
是什么原因?
布局具有fill_parent的高度和宽度,因此不会出现问题..

progressLayout.setGravity(Gravity.CENTER);
将textview和progressbar对齐在中心。

试用此解决方案
LinearLayout progressLayout = new LinearLayout(this);
progressLayout.setOrientation(LinearLayout.VERTICAL);
TextView t = new TextView(this);
t.setText("Test..");
t.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 20);
LayoutParams l = new LayoutParams(
android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
// ===> does not work?
// l.setMargins(50, 50, 50, 25);
// t.setLayoutParams(l);
l.leftMargin = 10;
l.topMargin = 0;
l.rightMargin = 0;
l.bottomMargin = 150;
ProgressBar circle = new ProgressBar(this, null,
android.R.attr.progressBarStyleLarge);
LayoutParams p = new LayoutParams(
android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
// circle.setLayoutParams(p);
p.leftMargin = 0;
p.topMargin = 0;
p.rightMargin = 0;
p.bottomMargin = 20;
progressLayout.setLayoutParams(new LayoutParams(
android.view.ViewGroup.LayoutParams.FILL_PARENT,
android.view.ViewGroup.LayoutParams.FILL_PARENT));
progressLayout.setGravity(Gravity.CENTER);
progressLayout.addView(t, l);
progressLayout.addView(circle, p);
this.setContentView(progressLayout);
