自定义的五种Toast

自定义的五种Toast，希望能够帮助到大家，上代码!

首先是activity_main.xml里面的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<Button
android:id="@+id/button_1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/toast_btn_1" >
</Button>

<Button
android:id="@+id/button_2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/toast_btn_2" >
</Button>

<Button
android:id="@+id/button_3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/toast_btn_3" >
</Button>

<Button
android:id="@+id/button_4"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/toast_btn_4" >
</Button>

<Button
android:id="@+id/button_5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/toast_btn_5" >
</Button>

</LinearLayout>

编写好布局之后，我们就来看看自定义Toast到底是怎么写的

package com.mytoast;

import java.util.Timer;
import java.util.TimerTask;

import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;

public class MyToast extends Activity implements OnClickListener {
//初始化显示的信息
//初始化Button
private Button toastBtn_1, toastBtn_2, toastBtn_3, toastBtn_4, toastBtn_5;
private Toast toast = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toastBtn_1 = (Button) findViewById(R.id.button_1);
toastBtn_2 = (Button) findViewById(R.id.button_2);
toastBtn_3 = (Button) findViewById(R.id.button_3);
toastBtn_4 = (Button) findViewById(R.id.button_4);
toastBtn_5 = (Button) findViewById(R.id.button_5);
toastBtn_1.setOnClickListener(this);
toastBtn_2.setOnClickListener(this);
toastBtn_3.setOnClickListener(this);
toastBtn_4.setOnClickListener(this);
toastBtn_5.setOnClickListener(this);
}

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
// AlertDialog.Builder builder;
// AlertDialog dialog;
switch (v.getId()) {
case R.id.button_1:
toast.makeText(this, "这是默认的Toast显示", Toast.LENGTH_LONG).show();
break;

case R.id.button_2:
toast = Toast.makeText(getApplicationContext(), "这是自定义位置的Toast显示",
Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
break;

case R.id.button_3:
toast = Toast.makeText(getApplicationContext(), "这是带图片的Toast显示",
Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 50, -100);
LinearLayout layout = (LinearLayout) toast.getView();
ImageView image = new ImageView(getApplicationContext());
image.setImageResource(R.drawable.wallpaper_tree_small);
layout.addView(image, 0);
toast.show();
break;

case R.id.button_4:
View view = LayoutInflater.from(getApplicationContext()).inflate(
R.layout.userdefinedtoast, null);
toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER, 0, 0);
toast.setView(view);
// toast.show();
// 设置延迟五秒显示
myToast();
break;

case R.id.button_5:
View view1 = LayoutInflater.from(getApplicationContext()).inflate(
R.layout.dialog_custom, null);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(view1);
AlertDialog alertDialog = builder.create();
alertDialog.show();
break;
}
}

// 设置延迟生效
private void myToast() {
Timer timer = new Timer();
timer.schedule(new TimerTask() {
@Override
public void run() {
initToast();
}
}, 5000);
}

private void initToast() {
toast.show();
}

}

这样一来就能够显示了，dialog_custom.xml的话我是这样写的，当然这都是随意的

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toast_layout"
android:layout_width="200dip"
android:layout_height="fill_parent"
android:background="#111111"
android:orientation="vertical" >

<TextView
android:id="@+id/txt_Title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|top"
android:text="@string/toast_text_1"
android:textColor="#ffffff"
android:textSize="20sp" >
</TextView>

<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#999999"
android:orientation="horizontal" >

<ImageView
android:id="@+id/image_toast"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dip"
android:src="@drawable/wallpaper_field_small" >
</ImageView>

<TextView
android:id="@+id/txt_context"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|right"
android:text="@string/toast_text_2"
android:textColor="#ffffff"
android:textSize="15dip" >
</TextView>
</LinearLayout>

</LinearLayout>

这样一来，完美的自定义Toast就能够实现了，都快试试吧。
