android 自定义Toast显示风格

1.创建一个自己想要显示Toast风格的XML如下代码（toast_xml.xml）：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:padding="8dp"
    android:background="#DAAA"
    android:id="@+id/toast_layout_root">

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginRight="8dp"
    android:id="@+id/iv"
    />
<TextView android:id="@+id/text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="#FFF"
    />
</LinearLayout>

2.封装一个Toast共同类，当然也可以直接在activity运用，那么我是用共通类，当然只是简单的封装：

import com.sbr.activity.R;

import android.annotation.SuppressLint;
import android.content.Context;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

@SuppressLint("ResourceAsColor")
public class ToastCommom {

    private static ToastCommom toastCommom;

    private Toast toast;

    private ToastCommom(){
    }

    public static ToastCommom createToastConfig(){
        if (toastCommom==null) {
            toastCommom = new ToastCommom();
        }
        return toastCommom;
    }

    /**
     * 显示Toast
     * @param context
     * @param root
     * @param tvString
     */

    public void ToastShow(Context context,ViewGroup root,String tvString){
        View layout = LayoutInflater.from(context).inflate(R.layout.toast_xml,root);
        TextView text = (TextView) layout.findViewById(R.id.text);
        ImageView mImageView = (ImageView) layout.findViewById(R.id.iv);
        mImageView.setBackgroundResource(R.drawable.ic_launcher);
        text.setText(tvString);
        text.setTextColor(R.color.aqua);
        toast = new Toast(context);
        toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
        toast.setDuration(Toast.LENGTH_LONG);
        toast.setView(layout);
        toast.show();
    }

}

3.创建一个Activity去引用该共通类：

import com.sbr.commonView.ToastCommom;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;

public class ToastActivity extends Activity {

    private Button mbutton;

    private ToastCommom toastCommom;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.toast_buton);
        toastCommom = ToastCommom.createToastConfig();
        mbutton = (Button) findViewById(R.id.btn);
        mbutton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                toastCommom.ToastShow(ToastActivity.this, (ViewGroup)findViewById(R.id.toast_layout_root), "你好");
            }
        });

    }

}

好了，一个简单的自定义toast显示就完成了；当然万变不离其宗，都是类似的做法。
