您可以按空格分割字符串,并将每个单词设置为spannable字符串.然后使spannable字符串可单击.这样您就不需要对String的长度进行硬编码.用户可以单击textview中的任何单词并突出显示.

public class MainActivity extends Activity {

TextView _tv;

String[] each;

SpannableString ss1;

Button b;

EditText et;

String s;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

b= (Button) findViewById(R.id.button1);

et = (EditText) findViewById(R.id.ed);

_tv = (TextView) findViewById( R.id.tv );

b.setOnClickListener(new OnClickListener()

{

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

s=et.getText().toString();

_tv.setText("");

for(int i=0;i

{

each = s.split("\\s+");

}

for(int i=0;i

{

System.out.println("................"+each[i]);

ss1= new SpannableString(each[i]);

ss1.setSpan(new MyClickableSpan(), 0, ss1.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

_tv.append(ss1);

_tv.append(" ");

}

_tv.setMovementMethod(LinkMovementMethod.getInstance());

}

});

}

class MyClickableSpan extends ClickableSpan{ //clickable span

public void onClick(View textView) {

//do something

Toast.makeText(MainActivity.this, "Clicked",

Toast.LENGTH_SHORT).show();

}

@Override

public void updateDrawState(TextPaint ds) {

ds.setColor(Color.BLACK);//set text color

ds.setUnderlineText(false); // set to false to remove underline

}

}

}

结果快照.
