## 问题 ##

TextView的粗体和斜体无法同时生效，要么显示斜体，要么显示粗体。  
错误代码：

tv_test3.setTypeface(Typeface.SANS_SERIF, Typeface.BOLD);
    tv_test3.setTypeface(Typeface.SANS_SERIF, Typeface.ITALIC);

正确示例：

tv_test3.setTypeface(Typeface.SANS_SERIF, Typeface.BOLD_ITALIC);

## 参考完整代码 ##

Activity

    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.widget.TextView;
    
    public class MainActivity extends AppCompatActivity {
        private TextView tv_test1;
        private TextView tv_test2;
        private TextView tv_test3;
        private TextView tv_test4;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            tv_test1 = findViewById(R.id.tv_test1);
            tv_test2 = findViewById(R.id.tv_test2);
            tv_test3 = findViewById(R.id.tv_test3);
            tv_test4 = findViewById(R.id.tv_test4);
    
            tv_test1.setTypeface(Typeface.SANS_SERIF, Typeface.BOLD);
            tv_test2.setTypeface(Typeface.SANS_SERIF, Typeface.ITALIC);
    
            tv_test3.setTypeface(Typeface.SANS_SERIF, Typeface.BOLD);
            tv_test3.setTypeface(Typeface.SANS_SERIF, Typeface.ITALIC);
