Android自定义Toast-白红宇

这是一个可以自定义Toast的UI的工具类。废话少说，直接上代码。

package com.newtonapple.zhangyiyan.zhangyiyan.utils;

import android.app.Activity;

import android.content.Context;

import android.os.Handler;

import android.view.Display;

import android.view.Gravity;

import android.view.LayoutInflater;

import android.view.View;

import android.view.WindowManager;

import android.widget.LinearLayout;

import android.widget.TextView;

import android.widget.Toast;

import com.newtonapple.zhangyiyan.R;

public class ToastUtils {

//直接显示Toastpublic static void show(Context context, String info) {    View view = getTextView(context, info);    Toast toast = new Toast(context);    toast.setView(view);    toast.show();}private static View getTextView(Context context,String info){    LayoutInflater inflater = LayoutInflater.from(context);    View view = inflater.inflate(R.layout.tv_toast, null);    TextView tv = (TextView) view.findViewById(R.id.tv_toast);    tv.setText(info);    return view;}//设置Toast可以显示多长时间public static void show(Context context, String info, final long duration) {    if (context == null)    {        return;    }    final Toast toast = Toast.makeText(context, info, Toast.LENGTH_SHORT);    toast.show();    Handler handler = new Handler();    handler.postDelayed(new Runnable() {        @Override        public void run() {            toast.cancel();        }    }, duration);}复制代码

//自定义样式的Toast

public static void showZhengZaiKaiTong(Context context) {

if (context == null)

{

return;

}

final Toast toast = Toast.makeText(context, "", Toast.LENGTH_SHORT);

//自定义Toast的布局

View view = LayoutInflater.from(context).inflate(R.layout.layout_toast,null,false);

LinearLayout ll_toash = (LinearLayout) view.findViewById(R.id.toast);

//布局文件中设置的宽高不顶用，需要重新设置;注意:不能设置最外层控件的宽高，会报空指针，可以设置第二层控件的宽高    Activity activity = (Activity) context;    WindowManager windowManager = activity.getWindowManager();    Display display = windowManager.getDefaultDisplay();    int screenWidth = display.getWidth();    int screenHeight = display.getHeight();    ll_toash.getLayoutParams().width = (int) (screenWidth*0.411);    ll_toash.getLayoutParams().height = (int) (screenHeight*0.18);    //设置吐司居中显示    toast.setGravity(Gravity.CENTER, 0, 0);    toast.setView(view);    toast.show();}//自定义样式的Toastpublic static void yiShanChu(Context context) {    if (context == null)    {        return;    }    final Toast toast = Toast.makeText(context, "", Toast.LENGTH_SHORT);    View view = LayoutInflater.from(context).inflate(R.layout.layout_toast_delete,null,false);    LinearLayout ll_toash = (LinearLayout) view.findViewById(R.id.toast);    //布局文件中设置的宽高不顶用，需要重新设置;注意:不能设置最外层控件的宽高，会报空指针，可以设置第二层控件的宽高    Activity activity = (Activity) context;    WindowManager windowManager = activity.getWindowManager();    Display display = windowManager.getDefaultDisplay();    int screenWidth = display.getWidth();    int screenHeight = display.getHeight();    ll_toash.getLayoutParams().width = (int) (screenWidth*0.411);    ll_toash.getLayoutParams().height = (int) (screenHeight*0.18);    //设置吐司居中显示    toast.setGravity(Gravity.CENTER, 0, 0);    toast.setView(view);    toast.show();}复制代码
