Try this:
if(ed_text.length() == 0 || ed_text.equals(""))
{
mTel1.setVisibility(View.GONE);
} else {
mTel1.setVisibility(View.VISIBLE);
}
Also, remember to always set visibility ="gone" in XML:
<TextView
android:id="@+id/tv_tel1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="3dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="3dp"
android:background="@drawable/border"
android:clickable="true"
android:padding="10dp"
android:textColor="#0066cc"
android:visibility="gone"
android:textSize="18sp" />

Simple , Change your code like this,
if (ed_text == null || ed_text.isEmpty()) {
mTel1.setVisibility(View.GONE);
} else {
mTel1.setVisibility(View.VISIBLE);
}

Did you try with:
if(ed_text.isEmpty())
{
mTel1.setVisibility(View.VISIBLE);
} else {
mTel1.setVisibility(View.GONE);
}
This should do the trick.
You should also check if you TextView is populated with DB data when you call this.

According to your question the answer is
if (tv.length() == 0) {
tv.setVisibility(View.GONE);
}
Or you can use
if (TextUtils.isEmpty(tv.getText()){
tv.setVisibility(View.GONE);
}

try this,
mTel1 = (TextView) findViewById(R.id.tv_tel1);
String ed_text = mTel1.getText().toString().trim();
if(ed_text!=null && ed_text.length()> 0)
{
mTel1.setVisibility(View.VISIBLE);
}
else
{
mTel1.setVisibility(View.GONE);
}
