ProgressDialogの色を変えたかったのでカスタムレイアウトをDialogにぶっこむ

ProgressDialogのProgressBarの色を変えようと思ったんだけど色いじるAPI見あたらなかったので、Dailogにカスタムレイアウトを突っ込んでみた。

とりあえずDialogで書いてから、DiaogFragmentでも書いてみた。

Dialogの方

public class MainActivity extends AppCompatActivity {
    private Dialog dialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (dialog == null) {
                    dialog = new Dialog(MainActivity.this);
                    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                    dialog.setContentView(R.layout.dialog);
                    ((TextView) dialog.findViewById(R.id.progressDialogMessage)).setText("Loading.....");
                    dialog.show();
                } else if (!dialog.isShowing()) {
                    dialog.show();
                } else {
                    dialog.dismiss();
                }
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.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();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

DialogFragmentの方
