我有一个主活动,它有一个可点击的链接来启动一个活动。现在显示的是文本视图中的“单击此处”。我想将其更改为:“查看疏散路线 - 单击此处”,其中“单击此处”是带下划线的文本。以下是我目前拥有的代码。
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView android:id="@+id/txtView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/txtView_5"
android:text=""
android:textSize="20sp"
android:textStyle="bold"/>
</RelativeLayout>
MainActivity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
boolean isGPS = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
AsyncRouteNames asyncRouteNames = new AsyncRouteNames();
asyncRouteNames.execute();
String mapStr = "Click Here";
SpannableString mapContent = new SpannableString(mapStr);
mapContent.setSpan(new UnderlineSpan(), 0, mapStr.length(), 0);
final TextView mapTxtView = (TextView) findViewById(R.id.txtView1);
mapTxtView.setText(mapContent);
mapTxtView.setTextColor(Color.BLUE);
Linkify.addLinks(mapTxtView, Linkify.ALL);
ConnectivityManager cm = (ConnectivityManager)this.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
boolean isMobile = false;
if (activeNetwork != null && activeNetwork.isConnected()){
isMobile = true;
}
if (isMobile){
mapTxtView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
MainActivity.this.startActivity(new Intent(MainActivity.this, EvacRouteTableActivity.class));
}
});
} else {
mapTxtView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
MainActivity.this.startActivity(new Intent(MainActivity.this, NoConnectionActivity.class));
}
});
}
}
