我想添加到我的应用程序 ScreenView,但我只是收到错误。
我的布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:background="@color/bg"
android:id="@+id/mainlayout"
tools:context=".NwActivity" android:baselineAligned="false">
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<TextView

<EditText

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/pAddA"
style="@style/Txt"
android:hint="@string/pHint" />
</RelativeLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="1"
android:id="@+id/rlB" >
<TextView
android:id="@+id/teamB"
android:text="@string/teamB"
android:textSize="24sp"

<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:text="@string/pAdd"
android:onClick="addB" />
</RelativeLayout>

</LinearLayout>
活动:
package some.program;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.EditText;
import android.widget.RelativeLayout;
public class NwActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_nw);
}
public int skid = 0;
public void addA(View view) {
if(skid < 14) {
skid = skid + 1;
//LinearLayout ll = (LinearLayout) findViewById(R.id.mainlayout);
RelativeLayout rl = (RelativeLayout) findViewById(R.id.rlA);
EditText et1 = new EditText(this);
et1.setHint(R.string.pHint);
String strID = "eta" + skid;
int nid = getResources().getIdentifier(strID, "id", this.getPackageName());
et1.setId(nid);
int oskid = skid - 1;
int oid;
String resID = "eta" + oskid;
oid = getResources().getIdentifier(resID, "id", this.getPackageName());
RelativeLayout.LayoutParams params1= new RelativeLayout.LayoutParams
( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params1.addRule(RelativeLayout.BELOW, oid);
params1.addRule(RelativeLayout.CENTER_HORIZONTAL);
et1.setLayoutParams(params1);
et1.setTextAppearance(this, R.style.Txt);
rl.addView(et1);
}
}
public void addB(View view) {
}
}
如何添加 ScrollView,不会弄乱我的布局?单击按钮时,应用程序正在创建 EditText 表单。一切正常,但所有 EditText 字段都不适合布局并且不会出现。
