当我运行我的代码时,由于TypeFace,它会产生一些例外 我有一个微调器,我希望它在我点击其中任何一个时更改字体系列 但它不起作用。
这是我的.java代码
public class Graduation extends ActionBarActivity {
ImageView imageView ;
Spinner spinner;
int fontSizeInt;
String[]items = { "12", "16", "18", "20", "24", "28" , "30" };

EditText et;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.graduation);
spinner = (Spinner)findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, items);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(
new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
int position = spinner.getSelectedItemPosition();
try
{
fontSizeInt = Integer.parseInt(items[position]);
}
catch (NumberFormatException e)
{
fontSizeInt = 12; // Default size.
}
et.setTextSize(TypedValue.COMPLEX_UNIT_SP, (float) fontSizeInt);
// TODO Auto-generated method stub
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
);
spinner1 = (Spinner)findViewById(R.id.spinner1);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, f_items);
spinner1.setAdapter(adapter1);
spinner1.setOnItemSelectedListener(
new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
int position = spinner1.getSelectedItemPosition();
try
{
if (position == 0 )
{
Typeface f = Typeface.createFromAsset(getBaseContext().getAssets(),"font/TimesNewRoman.ttf");
et.setTypeface(f);
}
if (position == 1 )
{
Typeface f = Typeface.createFromAsset(getBaseContext().getAssets(),"font/arial.ttf");
et.setTypeface(f);
}
}
catch (NumberFormatException e)
{
//

// TODO Auto-generated method stub
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
);
addListenerOnImageg1() ;

}
public void addListenerOnImageg1() {
final Context context = this;

imageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, g1.class);
startActivity(intent);
Intent intent1 = new Intent(context , g1.class);
intent1.putExtra("fn" , et.getText().toString());
intent1.putExtra("font_size", fontSizeInt);
startActivity(intent1);
}
}
@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;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

我不知道我的问题在哪里 我也有xml文件,没有错误..有spinner和et以及.java文件中定义的所有内容......
我也改变了我的陈述:
Typeface f = Typeface.createFromAsset(Graduation.this.getAssets(),"font/TimesNewRoman.ttf");
并且它给出了同样的错误..我该怎么办?
我的.ttf文件存在于bin / assets / font文件夹中。
我的文件扩展名是正确的。

您可以使用View的getContext()
方法获取当前的Context,然后使用它来获取资源:
Typeface font = Typeface.createFromAsset(getContext().getAssets(), "font/arial.ttf");
答案 1 :(得分:0)
试试这个 -
Typeface f = Typeface.createFromAsset(getApplicationContext().getAssets(),"font/Blue Highway.ttf");
使用getApplicationContext()。这是在我的地方工作。如果它不在您的项目中,那么您的ttf文件中存在问题
答案 2 :(得分:0)
您的代码是正确的。我建议检查你的字体文件,它可能不支持android或损坏。 您可以尝试使用任何其他字体文件或只是在Android文件系统中打开.ttf文件来检查它的兼容性。
答案 3 :(得分:0)
创建给定的两个字体对象下面的setContentView方法并在spinner
中使用它字体tf1 = Typeface.createFromAsset(getAssets(),“font / TimesNewRoman.ttf”);
字体tf2 = Typeface.createFromAsset(getAssets(),“font / arial.ttf”);
答案 4 :(得分:0)
我猜这个字体本身有问题。当操作系统中的本机代码尝试加载字体时会触发该错误,因为丢失的文件存在不同的消息,因此我认为它是找到文件但不喜欢它的原因。
尝试使用其他一些ttf文件可能会从其他目的地下载它,如果可能的话尝试使用otf扩展字体。
