Question

我的EditText中有数百行文本，我的编辑文本的高度设置为match_parent，但是，只有几行代码可见，使屏幕的其余部分为空。如何使文本填充我的编辑文本？

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="@drawable/vector"
android:orientation="vertical" >

<EditText
    android:id="@+id/ed"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/button2"
    android:layout_alignParentTop="true"
    android:layout_margin="5dp"
    android:background="#50dddddd"
    android:gravity="top|left"
    android:inputType="textMultiLine"
    android:lines="5"
    android:maxWidth="5.0dip"
    android:minWidth="10.0dip"
    android:scrollHorizontally="false"
    android:textColor="#424242"
    android:textStyle="bold" />

<Button
    android:id="@+id/button3"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Write File to Application SandBox"
    android:visibility="gone" />

<Button
    android:id="@+id/button4"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Read File from Application SandBox"
    android:visibility="gone" />

<Button
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="40dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_margin="5dp"
    android:background="@drawable/antivirus_btn2"
    android:text="  READ  "
    android:textColor="@drawable/antivirus_btn_text2" />

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="40dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:layout_margin="5dp"
    android:background="@drawable/antivirus_btn3"
    android:text="  SAVE  "
    android:textColor="@drawable/antivirus_btn_text3" />

使用LinearLayout而不是RelativeLayout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/vector"
android:orientation="vertical" >

<EditText
    android:id="@+id/ed"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="8"
    android:layout_margin="5dp"
    android:background="#50dddddd"
    android:gravity="top|left"
    android:inputType="textMultiLine"
    android:textColor="#424242"
    android:textStyle="bold" />

<Button
    android:id="@+id/button3"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1";
    android:text="Write File to Application SandBox"
    android:visibility="gone" />

<Button
    android:id="@+id/button4"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1";
    android:text="Read File from Application SandBox"
    android:visibility="gone" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:orientation="horizontal"
    android:layout_weight="1">

<Button
    android:id="@+id/button2"
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight="1";
    android:layout_margin="5dp"
    android:background="@drawable/antivirus_btn2"
    android:text="  READ  "
    android:textColor="@drawable/antivirus_btn_text2" />

<Button
    android:id="@+id/button1"
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight="1";
    android:layout_margin="5dp"
    android:background="@drawable/antivirus_btn3"
    android:text="  SAVE  "
    android:textColor="@drawable/antivirus_btn_text3" />
    </LinearLayout>
    </LinearLayout>

Answer 2

如果仔细观察，您的EditText的高度为wrap_content，而不是match_parent

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/vector"
android:orientation="vertical" >

<EditText
    android:id="@+id/ed"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

您需要将其修改为match_parent或fill_parent。
