如何在android中根据设备的宽度设置edittext的宽度？

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int screenWidth = metrics.widthPixels;

int editTextWidth = (int) (screenWidth * 0.8); // 设置为屏幕宽度的80%

EditText editText = findViewById(R.id.editText);
ViewGroup.LayoutParams params = editText.getLayoutParams();
params.width = editTextWidth;
editText.setLayoutParams(params);
