我最近将我的支持库更新到com.
android.support:appcompat-v7:25.1.0,之后如果我通过xml文件向EditText添加文本,TextInputLayout提示不会浮动.
我也看过this question,但它对我不起作用.
这是我的xml代码：
<android.support.design.widget.TextInputLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_marginBottom="16dp"
android:layout_marginEnd="16dp"
app:layout_constraintRight_toRightOf="parent"
android:layout_marginRight="16dp"
app:layout_constraintVertical_bias="0.0"
android:id="@+id/til1"
android:layout_marginStart="16dp"
app:layout_constraintLeft_toLeftOf="parent"
android:layout_marginLeft="16dp"
app:layout_constraintHorizontal_bias="0.33">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="From"
android:inputType="time"
android:text="09:00 AM"
android:id="@+id/from_mon"
android:textSize="14sp" />
</android.support.design.widget.TextInputLayout>
这是我的gradle依赖项：
dependencies {
compile fileTree(include: ['*.jar'],dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',{
exclude group: 'com.android.support',module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support.constraint:constraint-layout:1.0.0-beta4'
compile 'uk.co.chrisjenx:calligraphy:2.2.0'
compile 'com.android.support:design:25.1.0'
compile 'com.android.support:support-v4:25.1.0'
compile 'com.android.support:recyclerview-v7:25.1.0'
compile 'com.android.support:cardview-v7:25.1.0'
compile 'com.android.volley:volley:1.0.0'
compile 'com.github.bhargavms:DotLoader:1.0.1'
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'de.hdodenhof:circleimageview:2.1.0'
compile 'com.labo.kaji:fragmentanimations:0.1.1'
compile 'com.github.esafirm.android-image-picker:imagepicker:1.2.5'
testCompile 'junit:junit:4.12'
}
这就是问题
您可以清楚地看到提示正在浮动.
请指导.
解决方法
您必须提供TextInputLayout的提示并使用TextInputEditText而不是EditText
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="From">
<android.support.v7.widget.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="09:00 AM" />
</android.support.design.widget.TextInputLayout>
