android 动态布局

[java] view
plaincopy

/**

* 根据手机的分辨率从 px(像素) 的单位 转成为 dp

*/

ublic static int dip(Context context,int pxValue) {

return (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,pxValue, context.getResources().getDisplayMetrics());



xml布局与动态代码结合，取得需要的layout

[java] view
plaincopy

LayoutInflater inflater = LayoutInflater.from(this);

LinearLayout linearLayout2 = (LinearLayout)inflater.inflate(R.layout.chinesean_detail, null);

1、android:layout_margin 的动态设置：

[java] view
plaincopy

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);

lp.setMargins(20,20,20,20);

xxxLayout.addView(xxxView,lp);

2、android:layout_weight：

[java] view
plaincopy

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT,1.0f);

这里的第三个参数就是设置android:layout_weight的属性

3、android:layout_gravity="center_vertical"设置

[java] view
plaincopy

LinearLayout.LayoutParams layoutParamsImage = new LinearLayout.LayoutParams(dip(context,50),dip(context,50),2.0f);

layoutParamsImage.gravity = Gravity.CENTER_VERTICAL;

4、设置文字粗体 android:textStyle="bold"

[java] view
plaincopy

textView1.getPaint().setFakeBoldText(true);
