我在我的android应用程序中使用Text to speech.它与Google TTs和espeak工作正常,但是当我使用Samsung TTS时,它会给出以下异常.

java.lang.IllegalArgumentException: Invalid int: "OS"

我在我的Android应用程序中实现了tts.它支持Android设备中默认TTS支持的所有语言.但是有可能获得在默认TTS中选择的语言名称,即在设置中在Google TTS中选择的语言名称吗？

我想在我的Android应用程序中实现两个手指轻扫手势.我使用了以下代码:

void handleTouch(MotionEvent m){
//Number of touches
int pointerCount = m.getPointerCount();
if(pointerCount == 2){
    int action = m.getActionMasked();
    int actionIndex = m.getActionIndex();
    String actionString;
    TextView tv = (TextView) findViewById(R.id.testDiffText);
    switch (action)
    {
        case MotionEvent.ACTION_DOWN:                   
            GLOBAL_TOUCH_POSITION_X = (int) m.getX(1);
            actionString = "DOWN"+" current "+GLOBAL_TOUCH_CURRENT_POSITION_X+" prev "+GLOBAL_TOUCH_POSITION_X;
            tv.setText(actionString);
            break;
        case MotionEvent.ACTION_UP:                 
            GLOBAL_TOUCH_CURRENT_POSITION_X = 0;
            actionString = "UP"+" current "+GLOBAL_TOUCH_CURRENT_POSITION_X+" prev "+GLOBAL_TOUCH_POSITION_X;
            tv.setText(actionString);  
            break;  
        case MotionEvent.ACTION_MOVE:
            GLOBAL_TOUCH_CURRENT_POSITION_X = (int) m.getX(1);
            int diff = GLOBAL_TOUCH_POSITION_X-GLOBAL_TOUCH_CURRENT_POSITION_X;
            actionString = "Diff "+diff+" current "+GLOBAL_TOUCH_CURRENT_POSITION_X+" prev "+GLOBAL_TOUCH_POSITION_X;
            tv.setText(actionString); …
