Create rounded_corner.xml in the drawable folder and add the following content, <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" > <stroke android:width="1dp" android:color="@color/common_border_color" /> <solid android:color="#ffffff" /> <padding android:left="1dp" android:right="1dp" android:bottom="1dp" android:top="1dp" /> <corners android:radius="5dp" /> </shape> Set this drawable in the TextView background property like so: android:background="@drawable/rounded_corner"

我希望这对你有用。

把你的TextView内MaterialCardView:

    <com.google.android.material.card.MaterialCardView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:cardCornerRadius="25dp"
        >
        <com.google.android.material.textview.MaterialTextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/emergency_sms_template"
            android:padding="6dp"
            android:textSize="11sp"
            />
    </com.google.android.material.card.MaterialCardView>

右键单击可绘制文件夹并创建新文件 根据您的要求命名文件，并将扩展名添加为.xml。 在文件中添加以下代码

  <?xml version="1.0" encoding="utf-8"?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android"
      android:shape="rectangle">
      <corners android:radius="5dp" />
      <stroke android:width="1dp"  />
      <solid android:color="#1e90ff" />
  </shape>

添加你想要的圆角边android:background="@drawable/corner"

你可以使用SVG圆角和加载到一个ImageView和使用ConstraintLayout带来ImageView的TextView

我用它圆润ImageView和圆润TextView

有两个步骤

1)在你的可绘制文件夹中创建这个文件:- rounded_corner.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
         <corners android:radius="10dp" />  // set radius of corner
         <stroke android:width="2dp" android:color="#ff3478" /> // set color and width of border
         <solid android:color="#FFFFFF" /> // inner bgcolor
</shape>

2)设置这个文件到你的TextView作为背景属性。

android:background="@drawable/rounded_corner"

你也可以在Button或Edittext中使用这个drawable

Create rounded_corner.xml in the drawable folder and add the following content, <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" > <stroke android:width="1dp" android:color="@color/common_border_color" /> <solid android:color="#ffffff" /> <padding android:left="1dp" android:right="1dp" android:bottom="1dp" android:top="1dp" /> <corners android:radius="5dp" /> </shape> Set this drawable in the TextView background property like so: android:background="@drawable/rounded_corner"
