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）：

[html] view plaincopyprint?





<?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：

[html] view plaincopyprint?





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：

[html] view plaincopyprint?





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。
