选中“为textView和editText添加边框形状”时,

您应该使用可绘制选择器来实现您的UI。

background_edit_text_default.xml 当用户没有选择EditText时,它是EditText的背景。

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <stroke
        android:width="1dp"
        android:color="#333D46" />

    <padding
        android:bottom="10dp"
        android:left="10dp"
        android:right="10dp"
        android:top="10dp" />
</shape>

然后创建一个 background_edit_text_selected.xml 当用户选择EditText时,它是EditText的背景。

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <stroke
        android:width="1dp"
        android:color="#EDB90E" />

    <padding
        android:bottom="10dp"
        android:left="10dp"
        android:right="10dp"
        android:top="10dp" />
</shape>

下一步创建 background_edit_text.xml 将用作EditText的背景。

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/background_edit_text_default" android:state_focused="false" />
    <item android:drawable="@drawable/background_edit_text_selected" android:state_focused="true" />

</selector>

最终设定 作为布局文件中EditText的背景,例如 activity_main .

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/conteiner"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="20dp"
    android:orientation="vertical">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/background_edit_text" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="10dp" />

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/background_edit_text" />

</LinearLayout>

您已经完成了,不需要在代码中添加任何内容。

主要活动

public class MainActivity extends AppCompatActivity {

    EditText edtEmail, edtPassword;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        edtEmail = findViewById(R.id.edtEmail);
        edtPassword = findViewById(R.id.edtPassword);

        edtEmail.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus)
                    edtEmail.setBackground(ContextCompat.getDrawable(MainActivity.this, R.drawable.edt_focus_bg));
                else
                    edtEmail.setBackground(ContextCompat.getDrawable(MainActivity.this, R.drawable.edt_unfocus_bg));
            }
        });

        edtPassword.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus)
                    edtPassword.setBackground(ContextCompat.getDrawable(MainActivity.this, R.drawable.edt_focus_bg));
                else
                    edtPassword.setBackground(ContextCompat.getDrawable(MainActivity.this, R.drawable.edt_unfocus_bg));
            }
        });


    }

}

编辑

TextView 然后执行以下步骤

• 创建 tv_text_color.xml res/color 目录式

• 创建 tv_bg.xml res/drawable 目录式

的示例代码

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Focused and not pressed -->
    <item android:state_focused="true"
        android:state_pressed="false"
        android:color="#000000" />
    <!-- Focused and pressed -->
    <item android:state_focused="true"
        android:state_pressed="true"
        android:color="#fae81e" />

    <!-- Unfocused and pressed -->
    <item android:state_focused="false"
        android:state_pressed="true"
        android:color="#fae81e" />

    <!-- Default color -->
    <item android:color="#000000" />
</selector>

的示例代码 电视_bg.xml文件

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/edt_focus_bg" 
        android:state_selected="true"/>
    <item android:drawable="@drawable/edt_focus_bg"
        android:state_pressed="true"/>
    <item android:drawable="@drawable/edt_unfocus_bg"/>

</selector>

现在在你的文本视图中这样使用

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginStart="10dp"
    android:layout_marginTop="30dp"
    android:layout_marginEnd="10dp"
    android:textColor="@color/tv_text_color"
    android:background="@drawable/tv_bg"
    android:clickable="true"
    android:gravity="center"
    android:text="Login"
    />

输出 具有 textview

你也可以做同样的效果 EditText 使用选择器

创建 edt_selector.xml 分辨率/可绘制 目录如下

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/edt_focus_bg"
        android:state_focused="true"/>
    <item android:drawable="@drawable/edt_unfocus_bg"/>

</selector> 

现在用在你的 editext 这样地

<EditText
    android:id="@+id/edtPassword"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginStart="10dp"
    android:layout_marginTop="5dp"
    android:layout_marginEnd="10dp"
    android:background="@drawable/edt_selector"
    android:imeOptions="actionNext"
    android:inputType="textPassword" />

       <shape xmlns:android="http://schemas.android.com/apk/res/android">
       <solid android:color="@android:color/transparent" />
       <corners android:radius="5dp" />
       <stroke
              android:width="3dp"
              android:color="@color/yellow" />
       </shape>

将其设置为EditText的背景 之后再创建一个 android:width="0dp" 当用户单击时,您可以简单地更改它们。

.....

editText1.setOnClickListener{
  editText1.setBackground(shape1);
  editText2.setBackground(shape0);
}
editText2.setOnClickListener{
  editText1.setBackground(shape0);
  editText2.setBackground(shape1);

}

将此添加到您的颜色文件夹:

选择器:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:color="your_border_color"/>
<item android:color="@android:color/transparent"/>
</selector>

背景:

<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="back_ground_color" />
<corners android:radius="5dp" />
<stroke
    android:width="3dp"
    android:color="@color/selector" />
</shape>

<EditText>
   android:background="@drawable/background"
</EditText>
