我使用相对布局在XML中制作了我的图像按钮。当我制作它们时它们看起来不错,但是当我在手机上运行时它会变小!我希望它扩展到我的设备的宽度(或任何设备的宽度)

这是我的XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<ImageButton
    android:id="@+id/prewedbutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/weddingbutton"
    android:layout_alignParentTop="true"
    android:layout_marginTop="90dp"
    android:contentDescription="@drawable/prewedbutton"
    android:src="@drawable/prewedbutton" />

<ImageButton
    android:id="@+id/weddingbutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="103dp"
    android:contentDescription="@drawable/weddingbutton"
    android:src="@drawable/weddingbutton" />

</RelativeLayout>

这是我的Java:

package com.example.ijazphotography;

import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
import android.content.Intent;

public class PhotographyActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_photography);
    // Show the Up button in the action bar.

        ImageButton prewed = (ImageButton) findViewById(R.id.prewedbutton);
        prewed.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
                Intent intent = new Intent(v.getContext(), PreWedActivity.class);
                startActivityForResult(intent, 0);

            }
        });

        ImageButton wed = (ImageButton) findViewById(R.id.weddingbutton);
        wed.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
                Intent intent = new Intent(v.getContext(), Wedding.class);
                startActivityForResult(intent, 0);
            }
        });
    }
}

更改android:layout_width =&#34; wrap_content&#34;到android:layout_width =&#34; match_parent&#34;它应该扩展到设备宽度。

如果您希望按钮占据父宽度,则可以将按钮的宽度更改为fill_parent

 android:layout_width="fill_parent"

    android:layout_height="match_parent"
    android:layout_alignLeft="@+id/weddingbutton"
    android:layout_alignParentTop="true"
    android:layout_marginTop="90dp"
    android:contentDescription="@drawable/prewedbutton"
    android:src="@drawable/prewedbutton" />

<ImageButton
    android:id="@id/weddingbutton"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="103dp"
