Question

我已在可绘制文件夹中将环形状定义为XML文件，如下所示

circle_normal.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="ring"
android:thicknessRatio="1.9"
android:useLevel="false" >

<solid android:color="#FF0000" />

<size
    android:height="10dp"
    android:width="10dp" />

<stroke
    android:width="1dp"
    android:color="#FFFFFF" />

<padding
    android:bottom="5dp"
    android:left="5dp"
    android:right="5dp"
    android:top="5dp" /></shape>

使用相应形状的布局为 faculty_details

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/background"
tools:context=".FacultyDetails" >

<TextView
    android:id="@+id/nameoffaculty"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="94dp"
    android:layout_marginTop="92dp"
    android:text="Large Text"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:textColor="#FFFFFF" />

<View
    android:id="@+id/viewundertextnarrow"
    android:layout_width="fill_parent"
    android:layout_height="1dp"
    android:layout_alignLeft="@+id/nameoffaculty"
    android:layout_below="@+id/nameoffaculty"
    android:background="#FFFFFF"
    android:paddingBottom="1dp"
    android:paddingTop="1dp" />


<View
    android:id="@+id/viewundertextbold"
    android:layout_width="fill_parent"
    android:layout_height="4dp"
    android:layout_alignLeft="@+id/nameoffaculty"
    android:layout_below="@+id/viewundertextnarrow"
    android:layout_marginTop="2dp"
    android:background="#FFFFFF"
    android:paddingBottom="1dp"
    android:paddingTop="1dp" />

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_marginRight="23dp"
    android:layout_toLeftOf="@+id/viewundertextbold"
    android:src="@drawable/phone_icon" />

<TextView
    android:id="@+id/phone_number"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/imageView1"
    android:layout_alignLeft="@+id/viewundertextbold"
    android:text="Large Text"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:textColor="#FFFFFF" />

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_marginLeft="36dp"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"
    android:paddingBottom="5dp"
    android:paddingTop="5dp"
    android:layout_toRightOf="@+id/phone_number" >

    <view
        android:id="@+id/viewv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/circle_normal" />
</RelativeLayout></RelativeLayout>

问题是圆圈的两边被切断，如图所示

即使将视图设置为wrap_content，也会选择从上到下的整个视图

java代码只不过是一个没有函数的活动 FacultyDetails

import android.app.Activity;    
import android.os.Bundle;    

public class FacultyDetails extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.faculty_details);
    int value = getIntent().getExtras().getInt("id_fromtable");

}

我不知道该怎么做我花了几天时间寻找解决方案，但注意到这些问题所以这是我的三个问题

1 - 视线被切断 2 - 视图填充整个布局 3 - 运行时出错，我不知道id

请帮助谢谢

Answer 1

如果您没有任何特定要求将形状用作响铃，则可以将形状更改为椭圆

或者如果您没有任何具体要求将厚度比保持在 1.9 ，您可以将其设置为 2

上述两种情况都应解决斩波问题。

视线被切断了
