为了验证编写了个例子
首先是输入法
public class RemoteKeyboard extends InputMethodService {
@Override public boolean onKeyDown(int keyCode, KeyEvent event) {
if (processKey(event, 0 != event.getRepeatCount()))
return true;
return super.onKeyDown(keyCode, event);
}
@Override public boolean onKeyUp(int keyCode, KeyEvent event) {
if (processKey(event, true))
return true;
return super.onKeyUp(keyCode, event);
}
private boolean processKey(KeyEvent event, boolean doIt) {
Log.e("======= " ," ============ processKey");
return false;
}
} final TextView et1 = (TextView)findViewById(R.id.editText1);
et1.setOnKeyListener(new OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event)
{
Log.e("====================","====OnKeyListener ");
}============================ : ============ processKey
==================== :====OnKeyListener
============================ : ============ processKey
==================== :====OnKeyListener
第一遍应该是KeyDown, 第二遍应该是 KeyUp, 说明Android 输入法截取key优先于view
又试验了一下改写system/usr/keychars/Generic.kcm
把 B 改为
key B {
base: ‘b‘ fallback DPAD_CENTER
}
在一个不可编辑框, log 如下
12-23 05:18:09.093 118 118 E ============================ : ============ processKey
12-23 05:18:09.094 118 118 E ============================ : ============ processKey
12-23 05:18:09.163 118 118 E ============================ : ============ processKey
12-23 05:18:09.163 118 118 E ============================ : ============ processKey
说明b没有被 accept,而后又调用了 DPAD_CENTER
在一个可编辑框,b被accept, log 如下
============================ : ============ processKey
============================ : ============ processKey
说明没有调用 fallback
如果改法如下
key B {
base: fallback DPAD_CENTER
}
在一个可编辑框也要打4行log, 说明 fallback被调用了
