This article is about how Android implements the ProgressBar progress bar and the ProgressDialog progress box. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

When doing mobile phone development, we often encounter some time-consuming operations, when the progress bar begins to come in handy.

This demo shows the ProgressBar progress bar and the ProgressDialog progress box.

1. ProgressDialog progress box

The code is as follows:

/ / Progress dialog button monitoring

Class ProssButtonListener implements OnClickListener {

@ Override

Public void onClick (View v) {

MyDialog = ProgressDialog.show (ProgressbarDemo.this, "Progress Bar title"

"Progress bar content", true)

New Thread () {

Public void run () {

Try {

/ * write the program snippet to be run in the background here * /

/ * in order to see the effect, pause for 3 seconds is used as a demonstration * /

Sleep (3000)

} catch (Exception e) {

E.printStackTrace ()

} finally {

/ / Uninstall the created myDialog object.

MyDialog.dismiss ()

}

}

}. Start (); / * start running thread * /

}

}

Second, the progress bar dialog box, here with two cases to dynamically display the progress bar scale

1. Handle method

The code is as follows:

/ / Progress bar handle button listening

Class ProssBarHandleButtonListener implements OnClickListener {

@ Override

Public void onClick (View v) {

ProgressBarHandle.setVisibility (View.VISIBLE)

MyProssBarhandleText.setVisibility (View.VISIBLE)

ProgressBarHandle.setMax (1000)

New Thread () {

Public void run () {
