Question

在下面发布的代码中，我无法在单行中看到文本，而且我一次只想显示6个文本，但我能够看到超过20个文本。你有没有看过它为什么......

我需要我的观点是这样的，全视图应该由6个文本仅3个3覆盖

Mainactivity.java

package com.example.sampleoporj;
import android.os.Bundle;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.HorizontalScrollView;
import android.widget.LinearLayout;

public class MainActivity extends Activity {

    Button mbutton;
    MainActivity activity;
    LinearLayout mEventsLayout;
    HorizontalScrollView mHorizontalscroll;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        mbutton = (Button)findViewById(R.id.button1);
        mEventsLayout = (LinearLayout)findViewById(R.id.eventslayout);


        mbutton.setOnClickListener(btnlistener);
        activity = this;


    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }


    OnClickListener btnlistener = new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            for(int i = 0 ;i <10 ; i++)
            {

                LayoutInflater inflater = activity.getLayoutInflater();


                View view = (View)inflater.inflate(R.layout.samplelayout,null);

                mEventsLayout.addView(view);

            }
        }
    };

}

activity_main.xml中

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

            android:orientation="vertical" >

            <ImageView

            <TextView

                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:text="Medium Text"
                android:textAppearance="?android:attr/textAppearanceMedium" />

                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:text="Medium Text"
                android:textAppearance="?android:attr/textAppearanceMedium" />

            <TextView
                android:id="@+id/textView6"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:text="Medium Text"
                android:textAppearance="?android:attr/textAppearanceMedium" />

        </LinearLayout>

    </LinearLayout>

</RelativeLayout>

我要求输出应该是这样的，我需要一个水平滚动＆amp;在一次我只需要3 + 3文本显示（在图像中我只显示2 + 2）。正如我注意到，如果我使用“fill_parent”参数添加linearlayout，水平滚动会缩小。
