嗨，我在将按钮放置在屏幕底部时遇到问题，我已经将其布局，并且在 Eclipse 的图形布局中，它看起来正是我想要的，但是当我在设备上运行它时，按钮都转到了非常底端筛分位置相同。所以只有一个按钮可见。有谁知道这是为什么，或者你知道如何将东西 s 放在底部并加一点填充？
这是我尝试过的
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/ic_background_credits"
android:orientation="vertical" >
<Button
android:id="@+id/fm"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="38dp"
android:background="@drawable/fmbtn" />
<Button
android:id="@+id/ph"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/fm"
android:layout_alignLeft="@+id/fm"
android:background="@drawable/visitphbtn" />
</RelativeLayout>
这是我的代码，我在其中夸大了这个视图
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
//Check Preferences which sets UI
setContentView(R.layout.singlenews);
findViewById(R.id.progress).setVisibility(View.GONE);
loadData();
Button backbtn = (Button) findViewById(R.id.backbtn);
//Listening to button event
backbtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
//Starting a new Intent
Intent previousScreen = new Intent(getApplicationContext(), InfoActivity.class);
startActivity(previousScreen);
}
});
}
public void loadData(){
name = getIntent().getStringExtra("name");
Log.v("lc", "infoname=" + name);
if (name.equals(name1")) {
NewsView = LayoutInflater.from(getBaseContext()).inflate(R.layout.infodetail,
null);

headerText.setText("About name1");
