Question

所以我有一个自定义吐司，它的工作正常，除了曾经出现在屏幕上并点击它，应用程序崩溃的事实。的 toast.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toast_layout_root"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:background="#70716f" >

<ImageView android:id="@+id/image"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_marginRight="10dp" />

<TextView android:id="@+id/text"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:textColor="#FFF" />

爪哇：

    public Toast doToast(String chooseToast) {
    LayoutInflater inflater = getLayoutInflater();
    View layout = inflater.inflate(R.layout.toast,
            (ViewGroup) findViewById(R.id.toast_layout_root));

    ImageView image = (ImageView) layout.findViewById(R.id.image);
    image.setImageResource(R.drawable.icon_attention);
    TextView text = (TextView) layout.findViewById(R.id.text);
    text.setText(chooseToast);

    Toast toast = new Toast(getApplicationContext());
    toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(layout);
    return toast;
}

所以，如果我想创建一个带有“Hey”消息的Toast，那就像是：

Toast messageToast = doToast("Hey");
messageToast.show();

崩溃日志：

Answer 1

public void showToast(String message){
 Context context = getApplicationContext();
    // Create layout inflator object to inflate toast.xml file
    LayoutInflater inflater = getLayoutInflater();

    // Call toast.xml file for toast layout 
    View toastRoot = inflater.inflate(R.layout.toast, null);

 ImageView image = (ImageView) toastRoot.findViewById(R.id.image);
image.setImageResource(R.drawable.icon_attention);
TextView text = (TextView) toastRoot.findViewById(R.id.text);
text.setText(chooseToast);

    Toast toast = new Toast(context);

    // Set layout to toast 
    toast.setView(toastRoot);
    toast.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL,
            0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.show();

}
