EditText焦点问题

1、在一个Activity中加入一个EditText后，每次进入这个Activity时输入法都会自己主动弹出来。非常烦，找了些资料，在此记下解决的方法：

<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:focusableInTouchMode="true"
android:orientation="vertical" >

<EditText
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:background="@null"
android:inputType="text"
android:padding="3dp"
android:singleLine="true"
android:textColor="#666666"
android:textColorHint="#777777" />
</LinearLayout>

mTitleEdit = (EditText)findViewById(R.id.share_title_edit);
mTitleEdit.setOnFocusChangeListener(onFocusChangeListener);
mContentEdit = (EditText)findViewById(R.id.share_content_edit);
mContentEdit.setOnFocusChangeListener(onFocusChangeListener);

private OnFocusChangeListener onFocusChangeListener = new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus) {
SystemUtils.showSoftInput(SharePubActivity.this, v);
} else {
SystemUtils.hideSoftInput(SharePubActivity.this, v);
}
}
};

public static void showSoftInput(Context context, View v) {
InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(v, 0);
}

public static void hideSoftInput(Context context, View v) {
InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
