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
xml文件：(我目前使用的是LinearLayout)
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}$")) ){
pwdstrlevel.setProgress(20);
Toast.makeText(enroll.this,"密码强度：很弱",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z]\\D{5,10}$")){
pwdstrlevel.setProgress(20);
Toast.makeText(enroll.this,"密码强度：很弱",Toast.LENGTH_SHORT).show();
}
else if(str.matches("[a-zA-Z]{6,11}$")){
pwdstrlevel.setProgress(20);
Toast.makeText(enroll.this,"密码强度：很弱",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z]\\W{5,10}$")){
pwdstrlevel.setProgress(35);
Toast.makeText(enroll.this,"密码强度：中下",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z][\\d\\W]{5,10}$")){
pwdstrlevel.setProgress(50);
Toast.makeText(enroll.this,"密码强度：中",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z][\\D\\W]{5,10}$")){
pwdstrlevel.setProgress(50);
Toast.makeText(enroll.this,"密码强度：中",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z]\\w{5,10}$")){
pwdstrlevel.setProgress(35);
Toast.makeText(enroll.this,"密码强度：中下",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z][\\w\\W]{5,10}$")){
pwdstrlevel.setProgress(50);
Toast.makeText(enroll.this,"密码强度：中",Toast.LENGTH_SHORT).show();
}
else if(str.matches(("^[a-zA-Z]\\d{11,}$")) ){
pwdstrlevel.setProgress(50);
Toast.makeText(enroll.this,"密码强度：中",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z]\\D{11,}$")){
pwdstrlevel.setProgress(50);
Toast.makeText(enroll.this,"密码强度：中",Toast.LENGTH_SHORT).show();
}
else if(str.matches("[a-zA-Z]{12,}$")){
pwdstrlevel.setProgress(75);
Toast.makeText(enroll.this,"密码强度：中上",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z]\\W{11,}$")){
pwdstrlevel.setProgress(75);
Toast.makeText(enroll.this,"密码强度：中上",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z][\\d\\W]{11,}$")){
pwdstrlevel.setProgress(75);
Toast.makeText(enroll.this,"密码强度：中上",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z][\\D\\W]{11,}$")){
pwdstrlevel.setProgress(75);
Toast.makeText(enroll.this,"密码强度：中上",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z]\\w{11,}$")){
pwdstrlevel.setProgress(75);
Toast.makeText(enroll.this,"密码强度：中上",Toast.LENGTH_SHORT).show();
}
else if(str.matches("^[a-zA-Z][\\w\\W]{11,}$")){
pwdstrlevel.setProgress(100);
Toast.makeText(enroll.this,"密码强度：强",Toast.LENGTH_SHORT).show();
}
else{
pwdstrlevel.setProgress(0);
Toast.makeText(enroll.this,"密码格式错误",Toast.LENGTH_SHORT).show();
}
}
});
}
对于输入两次密码的比较可以自己补写。
