如何以编程方式添加片段的RelativeLayout [英] How to add fragments programmatically in relativelayout
本文介绍了如何以编程方式添加片段的RelativeLayout的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经设计了一个RelativeLayout的。我试图片段添加到它。它重叠。什么我需要做的，这样它涉及以下任一其他。
FragmentTransaction T = getSupportFragmentManager（）调用BeginTransaction（）; FragmentTest myFragment =新FragmentTest（）;
t.add（layout.getId（），myFragmentmyFirstFragment）; FragmentTest myFragment2 =新FragmentTest（）;
t.add（layout.getId（），myFragment2mySecondFragment）; t.commit（）;
myFragment和myFragment2的意见//重叠，即使我已经设置了方向垂直。
＆LT; RelativeLayout的
机器人：ID =@ + ID / idll1
机器人：layout_width =FILL_PARENT
机器人：layout_height =50dp
机器人：layout_marginLeft =10SP
机器人：layout_marginRight =0SP
机器人：layout_marginTop =10SP
机器人：layout_weight =1
机器人：paddingBottom会=5DP
机器人：paddingLeft =10dp
机器人：paddingRight =5DP
机器人：paddingTop =5DP
机器人：方向=垂直/＆GT;
解决方案
我们可以按如下方式做到这一点：
Activity类中相对布局为present。让这种相对布局（mParentLayout）是活动的视图层次的根元素。
和该片段被添加到相对布局将在按钮（mGridBtn）下方的位置被mGridFragment 的

}
} 私人无效loadFragment（）{
mGridFragment =新DroidOpsFragments（）;
mFragmentTransc = mFragmentMgr.beginTransaction（）;
mFragmentTransc.add（mParentLayout.getId（），mGridFragment）;
mFragmentTransc.addToBackStack（NULL）;
mFragmentTransc.commit（）;
} 公共RelativeLayout.LayoutParams fetchLayoutParams（）{
RelativeLayout.LayoutParams PARAMS =新RelativeLayout.LayoutParams（
LayoutParams.MATCH_PARENT，LayoutParams.MATCH_PARENT）; //我们可以添加任何可用的规则的RelativeLayout，因此可以相应地定位
params.addRule（RelativeLayout.BELOW，mGridBtn.getId（））;
返回PARAMS;
}
}
相应片段类，这是在活动的布局定位与的

返回视图。
}}
I have designed a RelativeLayout. I am trying to add fragment to it. It overlaps. What do I need to do so that it comes one below other.
FragmentTransaction t = getSupportFragmentManager().beginTransaction();
FragmentTest myFragment = new FragmentTest();
t.add(layout.getId(), myFragment, "myFirstFragment");
FragmentTest myFragment2 = new FragmentTest();
t.add(layout.getId(), myFragment2, "mySecondFragment");
t.commit();
//Views of myFragment and myFragment2 overlaps even though I have set the orientation to vertical.
<RelativeLayout
android:id="@+id/idll1"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_marginLeft="10sp"
android:layout_marginRight="0sp"
android:layout_marginTop="10sp"
android:layout_weight="1"
android:paddingBottom="5dp"
android:paddingLeft="10dp"
android:paddingRight="5dp"
android:paddingTop="5dp"
android:orientation="vertical"/>
解决方案
We can do it as follows :
Activity class in which relative layout is present. Let that relative layout (mParentLayout) be root element of activity's view hierarchy. And the fragment to be added to the relative layout will be mGridFragment at a position below the Button (mGridBtn).
public class DroidOpsActivity extends FragmentActivity implements
OnClickListener {
private RelativeLayout mParentLayout = null;
private Button mGridBtn = null;
private FragmentManager mFragmentMgr = null;
private FragmentTransaction mFragmentTransc = null;
private Fragment mGridFragment = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initialize();
}
private void initialize() {
setContentView(R.layout.activity_droid_ops);
mParentLayout = (RelativeLayout) findViewById(R.id.parent_layout);
mGridBtn = (Button) findViewById(R.id.grid_button);
mFragmentMgr = getSupportFragmentManager();
registerListener();
}
private void registerListener() {
mGridBtn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.grid_button:
loadFragment();
mGridBtn.setEnabled(false);
break;
}
}
private void loadFragment() {
mGridFragment = new DroidOpsFragments();
mFragmentTransc = mFragmentMgr.beginTransaction();
mFragmentTransc.add(mParentLayout.getId(), mGridFragment);
mFragmentTransc.addToBackStack(null);
mFragmentTransc.commit();
}
public RelativeLayout.LayoutParams fetchLayoutParams() {
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
// We can add any rule available for RelativeLayout and hence can position accordingly
params.addRule(RelativeLayout.BELOW, mGridBtn.getId());
return params;
}
}
Corresponding Fragment class which is to be positioned with in the activity's layout.
public class DroidOpsFragments extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.view_word_grid, null);
// Here we are fetching the layoutParams from parent activity and setting it to the fragment's view.
view.setLayoutParams(((DroidOpsActivity) activity).fetchLayoutParams());
return view;
}
}
