java – Transluscent屏幕android

这是一个例子：

new AlertDialog.Builder(context)
.setView(inflater.inflate(R.layout.dialog_delete_contact,null))
.setPositiveButton(context.getResources().getString(android.R.string.ok).toUpperCase(),new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog,int which) {
        // YOUR TREATMENT
    }
})
.setNegativeButton(context.getResources().getString(android.R.string.cancel).toUpperCase(),null)
.show();

布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/GrayLight"
android:orientation="vertical" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:background="@color/Black"
    android:gravity="center"
    android:orientation="horizontal"
    tools:ignore="DisableBaselineAlignment" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:layout_weight="2"
        android:gravity="center"
        android:orientation="horizontal" >

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:contentDescription="@string/app_name"
            android:fitsSystemWindows="true"
            android:padding="10dip"
            android:src="@drawable/ic_launcher" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:layout_marginRight="20dp"
        android:layout_weight="0.5"
        android:gravity="center"
        android:orientation="horizontal" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/remove_contact"
            android:textColor="@color/White"
            android:textSize="20sp"
            android:textStyle="bold"
            tools:ignore="HardcodedText" />

    </LinearLayout>
</LinearLayout>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:gravity="center"
    android:orientation="vertical"
    tools:ignore="DisableBaselineAlignment" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingBottom="10dp"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:paddingTop="20dp"
        android:text="@string/ask_remove_contact"
        android:textSize="15sp"
        tools:ignore="HardcodedText" />

</LinearLayout>

为避免每次重写代码,这里是一个实用程序类：

public class MyDialog {

public static Builder create(final Context context,final LayoutInflater layoutInflater,final String title,final String content) {
    View view = layoutInflater.inflate(R.layout.generic_dialog,null);
    ((TextView)view.findViewById(R.id.textViewTitleDialog)).setText(title);
    ((TextView)view.findViewById(R.id.textViewContentDialog)).setText(content);
    return new AlertDialog.Builder(context).setView(view);
}

}

以及使用的一个例子：

AlertDialog.Builder myDialog = MyDialog.create(this,getLayoutInflater(),"Quitter ECOLEMS","Voulez-vous vraiment quitter l'application?");
myDialog.setPositiveButton("Oui",int id) {
        // YOUR TREATMENT
    }
})
.setNegativeButton("Non",null)
.show();
