如何在android中加载speak时显示进度对话框？
提问于 2018-06-03 07:06:06
我有一个按钮，可以说出超过4000个字符的文本。它也在正常工作。但当我点击按钮时，它需要时间来说话。因此，我想创建一个进度对话框，这样当我按下“发言”按钮时，它将显示进度对话框，之后，它将关闭，当它将开始发言。
private void loadSpeaking(String textForReading)
{
int dividerLimit = 3900;
if(textForReading.length() >= dividerLimit) {
int textLength = textForReading.length();
ArrayList<String> texts = new ArrayList<String>();
int count = textLength / dividerLimit + ((textLength % dividerLimit == 0) ? 0 : 1);
int start = 0;
int end = textForReading.indexOf(" ", dividerLimit);
for(int i = 1; i<=count; i++) {
texts.add(textForReading.substring(start, end));
start = end;
if((start + dividerLimit) < textLength) {
end = textForReading.indexOf(" ", start + dividerLimit);
}
else {
end = textLength;
}
}
for(int i=0; i<texts.size(); i++) {
textToSpeech.speak(texts.get(i), TextToSpeech.QUEUE_ADD, null);
}
} else {
textToSpeech.speak(textForReading, TextToSpeech.QUEUE_FLUSH, null);
}

为什么不使用简单的ProgressDialog呢？
试试这个：
private ProgressDialog dialog;
private void loadSpeaking(String textForReading)
{
dialog.setMessage("Please wait");
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
dialog.show();
int dividerLimit = 3900;
if(textForReading.length() >= dividerLimit) {
int textLength = textForReading.length();
ArrayList<String> texts = new ArrayList<String>();
int count = textLength / dividerLimit + ((textLength % dividerLimit == 0) ? 0 : 1);
int start = 0;
int end = textForReading.indexOf(" ", dividerLimit);
for(int i = 1; i<=count; i++) {
texts.add(textForReading.substring(start, end));
start = end;
if((start + dividerLimit) < textLength) {
end = textForReading.indexOf(" ", start + dividerLimit);
}
else {
end = textLength;
}
}
for(int i=0; i<texts.size(); i++) {
textToSpeech.speak(texts.get(i), TextToSpeech.QUEUE_ADD, null);
}
} else {
textToSpeech.speak(textForReading, TextToSpeech.QUEUE_FLUSH, null);
}
if (dialog.isShowing())
dialog.dismiss();
