Question

 layout=(RelativeLayout)findViewById(R.id.relate);
                TextView tv = new TextView(DetailActivity.this);
                layout.addView(tv);
                tv.setTextAppearance(DetailActivity.this, android.R.style.TextAppearance_Medium);
                tv.setGravity(Gravity.CENTER_HORIZONTAL);
                tv.setText("Hello Man");

以下是我的代码如何使用setTextAppearance for API＆gt; 23

帮助感谢

Answer 1

使用支持库中的TextViewCompat： TextViewCompat.setTextAppearance（tv，android.R.style.TextAppearance_Medium）;

Answer 2

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                titleTextView.setTextAppearance(R.style.TextAppearance_MaterialComponents_Headline6);
            } else {
                titleTextView.setTextAppearance(context, R.style.TextAppearance_MaterialComponents_Headline6);
            }

Answer 3

这意味着您不需要将上下文arg放在那里，您可以简单地设置样式ID。它现在自动获取上下文

Answer 4

对于API＆gt; 23，做：

tv.setTextAppearance(android.R.style.TextAppearance_Medium);

setTextAppearance不推荐使用android如何使用？
