我正在實施自定義相機，並且我在onPreviewFrame（）中使用實時fx。主效應（fx1）是可運行的，並且似乎可以，需要時丟幀。
第二個簡單的fx（fx2）在fx1關閉時運行。
當fx2在主線程上運行時沒問題（它運行在2毫秒內），但有時我看到一個ANR，所以我決定將它移動到第二個可運行狀態，但現在導致應用程序凍結。在將代碼移入可運行代碼後，Android應用程序凍結而無ANR
class FX2Runnable implements Runnable {
private byte[] data;
FX2Runnable(byte[] _data) {
data = _data;
}
public void run() {
hview.FX2(data);
hview.post(new Runnable() {
public void run() {
hview.postInvalidate();
//.invalidate(); caused ANR!!
}
});
FLAG_FX2_PROCESSING = false;
}
}
這是我如何稱呼它
private PreviewCallback previewCallback=new PreviewCallback() {
public void onPreviewFrame(byte[] data, Camera cam) {
if(FX==1) {
// FX1
if(FLAG_FX1_PROCESSING) {
//skip
} else {
FLAG_FX1_PROCESSING = true;
FX1Thread = new Thread(new FX1Runnable());
FX1Thread.start();
}
} else {
// FX2
if(FLAG_FX2_PROCESSING) {
//skip
} else {
FLAG_FX2_PROCESSING = true;
FX2Thread = new Thread(new FX2Runnable(data));
FX2Thread.start();
}
/* this was the old code and was working fine
but i needed to solve some spare ANR
//hview.FX2(data);
//hview.invalidate();
*/
}
}
}
我在做什麼錯！？
順便說一下，它似乎我不能凍結模擬器上的應用程序，但只能在我的設備上。
編輯
與runOnUiThread（Runnable接口），而不是hview.post（Runnable接口）嘗試，它似乎工作，但我不得不等待幾分鐘，看看再次冷凍的應用程序！它發生在後面，但它又發生了！
下面是一個logcat的

請幫助！
而不是使用'hview.post ...'，請嘗試使用'runOnUiThread（新的Runnable（）...' –
