Slider的使用
- 添加依賴:
implementation 'com.google.android.material:material:1.2.1'
- 若要使控件正常顯示,則對(duì)應(yīng)AppTheme應(yīng)該修改為:
<resources>
<!-- Base application theme.修改為如下主題 -->
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
</resources>
- 布局中引入Slider以及屬性說明
<com.google.android.material.slider.Slider
android:layout_marginTop="100dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:valueFrom="0f"
android:valueTo="100f"
android:value="20f"
app:haloColor="@color/color1"
app:haloRadius="20dp"
app:labelBehavior="withinBounds"
app:thumbColor="@color/color2"
app:thumbRadius="10dp"
app:thumbElevation="10dp"
app:trackColorActive="@color/color3"
app:trackColorInactive="@color/color4"
android:stepSize="1"
/>
android:valueFrom:滑動(dòng)起始點(diǎn)
android:valueTo:滑動(dòng)終點(diǎn)
android:value:滑動(dòng)起始值設(shè)定
app:haloColor:拖動(dòng)時(shí)出現(xiàn)的圓形顏色
app:haloRadius:拖動(dòng)時(shí)大圓的半徑
app:labelBehavior:滑動(dòng)時(shí)數(shù)值提示顯示()
app:thumbColor:滑塊的顏色設(shè)置
app:thumbRadius:滑塊的半徑
app:thumbElevation:滑塊陰影
app:trackColorActive:已經(jīng)拖動(dòng)的區(qū)域顏色
app:trackColorInactive:未覆蓋的區(qū)域
android:stepSize:步進(jìn)設(shè)置
常用方法調(diào)用和數(shù)值監(jiān)聽
private void initSlider(){
custom_slider = findViewById(R.id.slider_custom);
custom_slider.addOnChangeListener(new Slider.OnChangeListener() {
@Override
public void onValueChange(@NonNull Slider slider, float value, boolean fromUser) {
//此處可獲取相關(guān)滑動(dòng)數(shù)值
}
});
}
-
效果圖如下:

SnackBar的使用
- 確定好顯示的父布局,直接加載代碼即可
private void showSnackBar(){
LinearLayout activity_content = findViewById(R.id.activity_content);
Snackbar.make(activity_content,"標(biāo)題", Snackbar.LENGTH_LONG)
.setAction("點(diǎn)擊事件", new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,"Toast",Toast.LENGTH_SHORT).show();
}
}).setDuration(Snackbar.LENGTH_LONG).show();
}
-
顯示效果如下:

FloatingActionButton的使用
- 布局屬性解析
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_margin="20dp"
android:layout_alignParentEnd="true"
android:src="@drawable/ic_mic_black_24dp"
android:clickable="true"
app:backgroundTint="@color/color_normal"
android:elevation="3dp"
app:pressedTranslationZ="6dp"
app:fabSize="normal"
android:focusable="true"
app:rippleColor="@color/color_pressed"
/>
app:backgroundTint:按鈕背景顏色
android:elevation:陰影高度,該屬性使得控件有陰影,像浮起來一樣
app:pressedTranslationZ:按下的陰影顯示
app:fabSize:按鈕大小,兩種取值:normal、mini
app:rippleColor:按下波紋顯示
-
事件監(jiān)聽與Button一致,所以不再贅述,效果圖如下
