您可以创建自定义的烤面包，您可以在其中定义自己的布局。结账下面的代码。

命名为“custom_toast.xml”

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/toast_layout_root" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:layout_marginLeft="10dp" 
android:layout_marginRight="10dp" 
android:orientation="horizontal" 
android:paddingLeft="10dp" 
android:paddingRight="10dp" > 

<LinearLayout 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:background="#00AAE9" 
android:orientation="horizontal" 
android:paddingBottom="5dp" 
android:paddingTop="5dp" > 

<ImageView 
android:id="@+id/toastImage" 
android:layout_width="wrap_content" 
android:layout_height="fill_parent" 
android:layout_marginRight="10dp" 
android:src="@drawable/ic_warning" /> 

<TextView 
android:id="@+id/toastText" 
android:layout_width="wrap_content" 
android:layout_height="fill_parent" 
android:gravity="center_vertical" 
android:textColor="#FFFFFF" 
android:textSize="7pt" 
android:textStyle="italic" /> 
</LinearLayout> 

</LinearLayout> 

你的活动类

import android.os.Bundle; 
import android.app.Activity; 
import android.view.LayoutInflater; 
import android.view.Menu; 
import android.view.View; 
import android.view.ViewGroup; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.TextView; 
import android.widget.Toast; 

public class MainActivity extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 

Button toastButton = (Button) this.findViewById(R.id.toastButton); 
toastButton.setOnClickListener(new OnClickListener() { 
public void onClick(View v) { 
//create the toast object, set display duration, 
Toast.makeText(getApplicationContext(), "This is a plain toast.", 
Toast.LENGTH_SHORT).show(); 
} 
}); 

Button customToastButton = (Button) this.findViewById(R.id.customToastButton); 
customToastButton.setOnClickListener(new OnClickListener() { 
public void onClick(View v) { 

//get the LayoutInflater and inflate the custom_toast layout 
LayoutInflater inflater = getLayoutInflater(); 
View layout = inflater.inflate(R.layout.custom_toast, (ViewGroup) 
findViewById(R.id.toast_layout_root)); 

//get the TextView from the custom_toast layout 
TextView text = (TextView) layout.findViewById(R.id.toastText); 
text.setText("This is my custom toast"); 

//create the toast object, set display duration, 
//set the view as layout that's inflated above and then call show() 
Toast t = new Toast(getApplicationContext()); 
t.setDuration(Toast.LENGTH_LONG); 
t.setView(layout); 
t.show(); 
} 
}); 

} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
// Inflate the menu; this adds items to the action bar if it is present. 
getMenuInflater().inflate(R.menu.main, menu); 
return true; 
} 

}

您可以设置查看任何类型的对话框的XML布局或烤面包，以定制外观。吐司样本在山姆下面提到e适用于警报或进度对话框。

LayoutInflater inflater = getLayoutInflater(); 
View layout = inflater.inflate 
(R.layout.custom_toast,(ViewGroup) findViewById(R.id.toast_layout_root)); 
TextView text = (TextView) layout.findViewById(R.id.text); text.setText("This is a custom toast"); 
Toast toast = new Toast(getApplicationContext()); 
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0); 
toast.setDuration(Toast.LENGTH_LONG); 
toast.setView(layout); toast.show();
