java - 如何更改TextInputEditText的底线颜色和提示颜色？

Question

我正在使用 TextInputLayout 和 TetInputEditText 来获得 float 提示。现在我想更改提示的颜色和编辑文本的底线。我希望它在用户点击编辑文本时得到改变。

因此，我尝试更改编辑文本的 onClickListener 颜色。但是我没有发现颜色有任何变化。

xml 布局:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/white"
    android:orientation="vertical">


    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.design.widget.TextInputLayout
            android:id="@+id/input_layout_item_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:layout_marginTop="20dp"
            android:paddingTop="05dp">
        <android.support.design.widget.TextInputEditText
            android:layout_width="240dp"
            android:layout_height="45dp"
            android:id="@+id/editTextItemName"
            android:layout_gravity="center_horizontal"
            android:hint="@string/item_name"
            android:textSize="12sp" />
        </android.support.design.widget.TextInputLayout>
    </LinearLayout>

java代码:

      public void setUpUI(){

        edt_Item_Name = (TextInputEditText) findViewById(R.id.editTextItemName);
        edt_Item_quantity = (TextInputEditText)findViewById(R.id.editTextItemQuantity);
        edt_Item_Unit = (TextInputEditText)findViewById(R.id.editTextItemUnit);

        textInput_Item_name = (TextInputLayout)findViewById(R.id.input_layout_item_name);
        textInput_Item_quantity = (TextInputLayout)findViewById(R.id.input_layout_item_quantity);
        textInput_Item_Unit = (TextInputLayout)findViewById(R.id.input_layout_item_unit);

        edt_Item_Name.getBackground().mutate().setColorFilter(ContextCompat.getColor(this, R.color.edtColor), PorterDuff.Mode.SRC_ATOP);

        edt_Item_Name.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                edt_Item_Name.setHintTextColor(ContextCompat.getColor(SearchActivity.this, R.color.edtColor));
                edt_Item_Name.getBackground().mutate().setColorFilter(ContextCompat.getColor(SearchActivity.this, R.color.edtColor), PorterDuff.Mode.SRC_ATOP);
            }
        });
    }

}

我怎样才能做到这一点？

Answer 1

在 colors.xml 文件中定义颜色

<color name="colorControlNormal">#c5c5c5</color>
<color name="colorControlActivated">@color/accent</color>
<color name="colorControlHighlight">@color/accent</color>

并在 styles.xml 中创建样式

<style name="TextAppearence.App.TextInputLayout"  parent="@android:style/TextAppearance">
     <item name="android:textColor">@color/main_color</item>
</style>

并应用于您的 TextInputLayout

 app:hintTextAppearance="@style/TextAppearence.App.TextInputLayout"
 android:textColorHint="#0072BA"

将您的代码更改为:

 <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.design.widget.TextInputLayout
            android:id="@+id/input_layout_item_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:layout_marginTop="20dp"
            android:paddingTop="05dp"
            app:hintTextAppearance="@style/TextAppearence.App.TextInputLayout"
            android:textColorHint="#0072BA">
        <android.support.design.widget.TextInputEditText
            android:layout_width="240dp"
            android:layout_height="45dp"
            android:id="@+id/editTextItemName"
            android:layout_gravity="center_horizontal"
            android:hint="@string/item_name"
            android:textSize="12sp" />
        </android.support.design.widget.TextInputLayout>
    </LinearLayout>
