android自定义toast示例 android自定义toast|Android

你可以在android中创建自定义Toast。因此，你可以显示一些图像，例如祝贺或烤面包的损失。这意味着你现在可以自定义Toast了。
activity_main.xml拖动要显示在主活动上的组件。

< ?xml version="1.0" encoding="utf-8"?> < android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="example.srcmini.com.customtoast.MainActivity">< TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hello World!" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toRightOf="parent" app:layout_constraintTop_toTopOf="parent" />< /android.support.constraint.ConstraintLayout>

customtoast.xml【android自定义toast示例】在布局目录内创建另一个xml文件。在这里，我们在这个xml文件中有ImageView和TextView。

< ?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:id="@+id/custom_toast_layout" android:orientation="vertical" android:background="#F14E23" >< ImageView android:id="@+id/custom_toast_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:contentDescription="Hello world" android:src="http://www.srcmini.com/@drawable/jtp_logo"/>< TextView android:id="@+id/custom_toast_message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:contentDescription="To" android:text="srcmini custom Toast" /> < /LinearLayout>

活动类现在编写代码以显示自定义Toast。

package example.srcmini.com.customtoast; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.Gravity; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Toast; public class MainActivity extends AppCompatActivity {@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //Creating the LayoutInflater instance LayoutInflater li = getLayoutInflater(); //Getting the View object as defined in the customtoast.xml file View layout = li.inflate(R.layout.customtoast, (ViewGroup) findViewById(R.id.custom_toast_layout)); //Creating the Toast object Toast toast = new Toast(getApplicationContext()); toast.setDuration(Toast.LENGTH_SHORT); toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0); toast.setView(layout); //setting the view of custom toast layout toast.show(); } }

输出：
