开机广告页面2017流行样式 dialogTheme的dialog版本

---

一.自定义dialog的使用
1.定义一个类继承dialog
2.修改style
3.加载布局
4.指定dialog在屏幕中的位置

/自定义一个类继承dialog
public class AdDialog extends Dialog implements View.OnClickListener {
    private Context context;
    public AdDialog(Context context) {
        // 更改样式,把背景设置为透明的
        super(context, R.style.LocatonDialogStyle);
        this.context = context;
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        //加载dialog的布局
        setContentView(R.layout.view_location_dialog_dong);
        //拿到布局控件进行处理
        ImageView imageView = (ImageView) findViewById(R.id.mm);
        imageView.setOnClickListener(this);
        //初始化布局的位置
        initLayoutParams();
    }
    // 初始化布局的参数
    private void initLayoutParams() {
        // 布局的参数
        LayoutParams params = getWindow().getAttributes();
        params.gravity = Gravity.CENTER_HORIZONTAL | Gravity.CENTER;
        params.alpha = 1f;
        getWindow().setAttributes(params);
    }
    @Override
    public void onClick(View v) {
        dismiss();
    }
}

2.主页面代码

public class MainActivity extends AppCompatActivity {
    private RocketView mRocketView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        AdDialog dialog = new AdDialog(this);
        dialog.show();
    }
}

3.布局和样式

 <!--弹出对话框-->
    <style name="LocatonDialogStyle" parent="@android:style/Theme.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item><!-- 背景透明 -->
        <item name="android:windowAnimationStyle">@android:style/Theme.InputMethod</item>
    </style>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
     <ImageView
         android:id="@+id/mm"
         android:src="@drawable/donghomesuccess"
         android:layout_width="match_parent"
         android:layout_height="match_parent"/>
</RelativeLayout>

改良版本
修改了下dialog的样式，添加了一个error 并且添加error的点击事件

public class AdDialog extends Dialog implements View.OnClickListener{
    private Context context;
    public AdDialog(@NonNull Context context) {
        // 更改样式,把背景设置为透明的
        super(context, R.style.LocatonDialogStyle);
        this.context = context;
    }

    public AdDialog(@NonNull Context context, int themeResId) {
        // 更改样式,把背景设置为透明的
        super(context, R.style.LocatonDialogStyle);
        this.context = context;
    }

    protected AdDialog(@NonNull Context context, boolean cancelable, @Nullable OnCancelListener cancelListener) {
        // 更改样式,把背景设置为透明的
        super(context, R.style.LocatonDialogStyle);
        this.context = context;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //加载dialog的布局
        setContentView(R.layout.view_location_dialog_dong);
        //拿到布局控件进行处理
        ImageView imageView = (ImageView) findViewById(R.id.mm);
        ImageView dia_iv = (ImageView) findViewById(R.id.dia_iv);
//        imageView.setOnClickListener(this);
        dia_iv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dismiss();
            }
        });
        //初始化布局的位置
        initLayoutParams();
    }

    private void initLayoutParams() {
        WindowManager.LayoutParams params = getWindow().getAttributes();
        params.gravity = Gravity.CENTER_HORIZONTAL | Gravity.CENTER;
        params.alpha = 1f;
        getWindow().setAttributes(params);
    }

    @Override
    public void onClick(View view) {

    }
}

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:app="http://schemas.android.com/apk/res-auto"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical" >
    <ImageView
        android:id="@+id/mm"
        android:src="@mipmap/xj3"
        android:layout_width="200dp"
        android:layout_centerInParent="true"
        android:layout_height="270dp"/>

    <ImageView
        android:id="@+id/dia_iv"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_alignEnd="@+id/mm"
        android:layout_alignTop="@+id/mm"
        app:srcCompat="@mipmap/error"/>
    <!--dia_iv-->
</RelativeLayout>
