Android UI에서 둥근 사각형을 그리는 방법은 무엇입니까?

Android UI에서 둥근 사각형을 그려야합니다. 에 대해 동일한 모서리가 둥근 직사각형을 갖는 TextView하고하는 EditText것도 도움이 될 것입니다.

레이아웃 xml에서 다음을 수행하십시오.

   <shape xmlns:android="http://schemas.android.com/apk/res/android">
         <gradient
            android:endColor="@color/something"
            android:centerColor="@color/something_else"
            android:startColor="@color/something_else_still"
            android:angle="270" />
        <corners
            android:radius="3dp" />
        <padding
            android:left="10dp"
            android:top="10dp"
            android:right="10dp"
            android:bottom="10dp" />
    </shape>

android : radius를 변경하면 모서리의 "반올림"양을 변경할 수 있습니다.

나는 이것이 당신이 정확히 필요하다고 생각합니다.

둥근 사각형을 만드는 drawable (xml) 파일입니다. round_rect_shape.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <solid android:color="#ffffff" />

    <corners
        android:bottomLeftRadius="8dp"
        android:bottomRightRadius="8dp"
        android:topLeftRadius="8dp"
        android:topRightRadius="8dp" />

</shape>

여기 레이아웃 파일 : my_layout.xml

<LinearLayout
    android:id="@+id/linearLayout1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/round_rect_shape"
    android:orientation="vertical"
    android:padding="5dp" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Something text"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="#ff0000" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <requestFocus />
    </EditText>
</LinearLayout>

-> 위 코드에서 배경이있는 LinearLayout (둥근 사각형을 만드는 것이 핵심 역할입니다). 따라서 LinearLayout에 TextView, EditText ...와 같은 모든 뷰를 배치하여 배경을 모두의 둥근 사각형으로 볼 수 있습니다.

In monodroid, you can do like this for rounded rectangle, and then keeping this as a parent class, editbox and other layout features can be added.

 class CustomeView : TextView
    {
       public CustomeView (Context context, IAttributeSet ) : base (context, attrs)  
        {  
        }
       public CustomeView(Context context, IAttributeSet attrs, int defStyle) : base(context, attrs, defStyle)  
        {  
        }
       protected override void OnDraw(Android.Graphics.Canvas canvas)
       {
           base.OnDraw(canvas);
           Paint p = new Paint();
           p.Color = Color.White;
           canvas.DrawColor(Color.DarkOrange);

           Rect rect = new Rect(0,0,3,3);

           RectF rectF = new RectF(rect);


           canvas.DrawRoundRect( rectF, 1,1, p);



       }  
    }
}

<shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:padding="10dp"
  android:shape="rectangle">
    <solid android:color="@color/colorAccent" /> 
    <corners
      android:bottomLeftRadius="500dp"
      android:bottomRightRadius="500dp"
      android:topLeftRadius="500dp"
      android:topRightRadius="500dp" />
</shape>

Now, in which element you want to use this shape just add: android:background="@drawable/custom_round_ui_shape"

Create a new XML in drawable named "custom_round_ui_shape"

---

Right_click on the drawable and create new layout xml file in the name of for example button_background.xml. then copy and paste the following code. You can change it according your need.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="14dp" />
<solid android:color="@color/colorButton" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
<size
android:width="120dp"
android:height="40dp" />
</shape>

Now you can use it.

<Button
android:background="@drawable/button_background"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

Use CardView for Round Rectangle. CardView give more functionality like cardCornerRadius, cardBackgroundColor, cardElevation & many more. CardView make UI more suitable then Custom Round Rectangle drawable.
