androidstudio通过监听EDITTEXT密码动态输入并且通过progressbar实现密码强度的显示条

androidstudio通过监听EDITTEXT密码动态输入并且通过progressbar实现密码强度的显示条

一、xml文件

xml文件：(我目前使用的是LinearLayout)

二、java文件

java文件：

@Override
protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_enroll);
    EditText enrollpassword1 = (EditText) findViewById(R.id.enrollpassword1);
    ProgressBar pwdstrlevel = findViewById(R.id.progressbar);
    enrollpassword1.addTextChangedListener(new TextWatcher() {
    
	@Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
			Log.d("TAG","beforeTextChanged--------------->");
		}

	@Override
        public void afterTextChanged(Editable s) {
			Log.d("TAG","afterTextChanged--------------->");
        }

	@Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
			Log.d("TAG","onTextChanged--------------->");
            String str =enrollpassword1.getText().toString();
            if(str.matches(("^[a-zA-Z]\\d{5,10}$")) ){
				pwdstrlevel.setProgress(20);
                Toast.makeText(enroll.this,"密码强度：很弱",Toast.LENGTH_SHORT).show();
            }

                Toast.makeText(enroll.this,"密码强度：中上",Toast.LENGTH_SHORT).show();
            }
