Android防止点击事件穿透
Android Fragment点击事件穿透问题

---

在遮罩层配置如下属性，进行事件的拦截。

android:clickable="true"
android:focusable="true"

节选自：android开发播放声音文件

---

MediaPlayer mediaPlayer01;
mediaPlayer01 = MediaPlayer.create(YouActivity.this, R.raw.xxxx);
mediaPlayer01.start();

节选自：Android软键盘-显示隐藏软键盘

---

/**
 * 隐藏软键盘
 *
 * @param view
 */
protected void hideKeyboard(View view) {
    InputMethodManager imm = (InputMethodManager) view.getContext()
            .getSystemService(Context.INPUT_METHOD_SERVICE);
    if (imm != null) {
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
}

// 设置准备完成监听
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        // 准备完成后开始播放
        mp.start();
        // 设置静音
        mp.setVolume(0, 0);
    }
});

结果拦截器

Interceptor responseInterceptor = new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Response response = chain.proceed(chain.request());
        if (response.body() != null) {
            String json = response.body().string().replace("\"data\":null", "\"data\":{}");
            ResponseBody body = ResponseBody.create(response.body().contentType(), json);
            return response.newBuilder().body(body).build();
        }
        return response;
    }
};

判断异常类型

@Override
public void accept(Throwable throwable) throws Exception {
    if (throwable instanceof HttpException) {
        String json = ((HttpException) throwable).response().errorBody().string();
    }
}

1.定义AlertDialog透明样式

<style name="TransparentDialog" parent="Theme.AppCompat.Dialog">
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

2.创建AlertDialog

View view = LayoutInflater.from(context).inflate(R.layout.dialog_sure, null, false);
AlertDialog sureDialog = new AlertDialog.Builder(context, R.style.TransparentDialog).setView(view).create();
