如何在Android中為特定的textview設置字體？

Question

我跟着從台階上這個運行時崩潰我的應用程序。 下面是我的整個代碼。

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        TextView tx = (TextView)findViewById(R.id.textView5);
        Typeface tf = Typeface.createFromAsset(getAssets(),"fonts/myriad_pro_regular.ttf");
        tx.setTypeface(tf);
        setContentView(R.layout.activity_main);
    }
}

當我添加以下代碼時

TextView tx = (TextView)findViewById(R.id.textView5);
Typeface tf = Typeface.createFromAsset(getAssets(),"fonts/myriad_pro_regular.ttf");
tx.setTypeface(tf);

該應用程序崩潰了，我不知道我在這里做錯了什么。

Answer 1

您在初始化 textView 后設置了內容視圖。 這應該是正確的方法：

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
TextView tx = (TextView)findViewById(R.id.textView5);
Typeface tf = 
Typeface.createFromAsset(getAssets(),"fonts/myriad_pro_regular.ttf");
tx.setTypeface(tf);

}

Answer 2

首先將您的文本視圖初始化放在setContentView下。

這是工作代碼

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main);
        TextView tx = (TextView)findViewById(R.id.text);
        Typeface tf = Typeface.createFromAsset(getResources().getAssets(),"myriad_pro_regular.ttf");
        tx.setTypeface(tf);

    }
