通过SpannableStringBuilder来实现,它就像html里边的<span>元素改变指定文字的文字颜色或背景色
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String str="这是设置TextView部分文字背景颜色和前景颜色的demo!";
int bstart=str.indexOf("背景");
int bend=bstart+"背景".length();
int fstart=str.indexOf("前景");
int fend=fstart+"前景".length();
SpannableStringBuilder style=new SpannableStringBuilder(str);
style.setSpan(new BackgroundColorSpan(Color.RED),bstart,bend,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
style.setSpan(new ForegroundColorSpan(Color.RED),fstart,fend,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
TextView tvColor=(TextView) findViewById(R.id.tv_color);
tvColor.setText(style);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}android TextView 设置部分文字背景色和文字颜色
