Toast 我想咱們應該使用的都不少,通常咱們使用默認設置較多,可是默認設置每每不能知足咱們的需求,那咱們如今來自定義下:html
默認Toast:java
Toast.makeText(MainActivity.this,"點擊按鈕",Toast.LENGTH_SHORT).show();
設置Toast位置:android
經過setGravity設置Toast位置,能夠是 佈局
Gravity.CENTER:中間this
Gravity.BOTTOM:下方spa
Gravity.TOP:上方code
Gravity.RIGHT:右邊htm
Gravity.LEFT:左邊圖片
Toast toast = Toast.makeText(getApplicationContext(), "點擊按鈕", Toast.LENGTH_SHORT); toast.setGravity(Gravity.CENTER, 0, 0); toast.show();
Toast 也能夠是個佈局:這個佈局裏能夠是任何控件 圖片 文字 等ip
Toast toast2 = new Toast(MainActivity.this); View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.toast_custom, null); toast2.setView(view); toast2.setGravity(Gravity.CENTER, 0, 0); toast2.show();
下面附上一個 ToastUtil類:
public class ToastUitl { private static Toast toast; private static Toast toast2; /** * 初始化Toast(消息,時間) */ private static Toast initToast(CharSequence message, int duration) { if (toast == null) { toast = Toast.makeText(BaseApplication.getAppContext(), message, duration); } else { //設置文字 toast.setText(message); //設置存續期間 toast.setDuration(duration); } return toast; } /** * 短期顯示Toast(消息 String等) */ public static void showShort(CharSequence message) { initToast(message, Toast.LENGTH_SHORT).show(); } /** * 短期顯示Toast(資源id) */ public static void showShort(int strResId) { initToast(BaseApplication.getAppContext().getResources().getText(strResId), Toast.LENGTH_SHORT).show(); } /** * 長時間顯示Toast(消息 String等) */ public static void showLong(CharSequence message) { initToast(message, Toast.LENGTH_LONG).show(); } /** * 長時間顯示Toast(資源id) */ public static void showLong(int strResId) { initToast(BaseApplication.getAppContext().getResources().getText(strResId), Toast.LENGTH_LONG).show(); } /** * 自定義顯示Toast時間(消息 String等,時間) */ public static void show(CharSequence message, int duration) { initToast(message, duration).show(); } /** * 自定義顯示Toast時間(消息 資源id,時間) */ public static void show(int strResId, int duration) { initToast(BaseApplication.getAppContext().getResources().getText(strResId), duration).show(); } /** * 顯示有image的toast 這是個view */ public static Toast showToastWithImg(final String tvStr, final int imageResource) { if (toast2 == null) { toast2 = new Toast(BaseApplication.getAppContext()); } View view = LayoutInflater.from(BaseApplication.getAppContext()).inflate(R.layout.toast_custom, null); TextView tv = (TextView) view.findViewById(R.id.toast_custom_tv); tv.setText(TextUtils.isEmpty(tvStr) ? "" : tvStr); ImageView iv = (ImageView) view.findViewById(R.id.toast_custom_iv); if (imageResource > 0) { iv.setVisibility(View.VISIBLE); iv.setImageResource(imageResource); } else { iv.setVisibility(View.GONE); } toast2.setView(view); toast2.setGravity(Gravity.CENTER, 0, 0); toast2.show(); return toast2; } }
對應的佈局文件:此佈局文件根據本身需求自定義
<LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="10dp" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:orientation="vertical"> <ImageView android:layout_marginTop="10dp" android:id="@+id/toast_custom_iv" android:layout_width="60dp" android:layout_height="60dp" android:src="@mipmap/ic_launcher" android:layout_gravity="center"/> <TextView android:id="@+id/toast_custom_tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="5dp" android:textSize="16sp" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:layout_marginBottom="10dp" android:textColor="#000" tools:text="點擊toast" /> </LinearLayout>
補加:
自定義Toast 填充滿整個屏幕:
Toast toast2 = new Toast(MainActivity.this); View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.toast_custom, null); ImageView iv_toast = (ImageView) view.findViewById(R.id.iv_toast); TextView tv_toast = (TextView) view.findViewById(R.id.tv_toast); toast2.setView(view); toast2.setGravity(Gravity.FILL_HORIZONTAL | Gravity.VERTICAL_GRAVITY_MASK, 0, 0); toast2.show();注意:佈局文件要
android:layout_width="match_parent" android:layout_height="match_parent"
